Following on from the last two episodes that look at the dysfunctional and unexpected results that can from the seemly well intentioned call for "more planning", this week's episode takes a look at a similar paradox - the call for "more developers". We look at why "more developers" does not generally equal "greater output" - the unexpected operational overheads that a larger team generate. We look at some circumstances, when used with caution, increasing the headcount can be the right thing. And we look at suggestion for improving productivity without increase numbers.

Hello and welcome back to the Better ROI from Software Development podcast. Following on from the last two episodes that looked at how the well-intentioned call for more planning could produce dysfunctional and unexpected results, I wanted to look at a related problem, the call for "more developers".
It's a counter-intuitive paradox that has perplexed and unfortunately even hindered many software projects. The paradox of believing "more developers" automatically equates to "faster development".
Within the ever-dynamic realm of software development, one might be inclined to think, if our project is lagging, surely adding more developers will hasten its progress?
This thought process is deeply embedded in our management DNA, often referred to as the muscle memory approach. It finds its roots in traditional management theories dating back to the industrial revolution. More hands, after all, meant more products off the production line.
But, is this muscle memory betraying us in the realm of software development? Are more coding hands truly accelerating our journey towards project completion? Or are we inadvertently creating complexity that leads our projects into delays and spiralling costs?
In this episode, we'll dissect why the call for "more developers" frequently resonates within the project halls, explore the hidden and often un-anticipated costs of expanding development teams, and touch upon scenarios when, yes, adding more developers might actually be the right call.
Together, let's explore the management myths and uncover strategies to truly boost our software development efforts without falling into the "more developers" trap.
Let's start by stepping back into the annals of history. We find ourselves amidst the smoke and clamour of the Industrial Revolution, a time where machines and manpower vigorously danced the tune of burgeoning industries. It was a straightforward equation then. More hands indeed meant more output. When tasks are linear and labour was a pivotal component of the production, the correlation between headcount and the output was direct and largely proportional.
This brings us to a pertinent theory that has lingered, perhaps even overstayed, in the corridors of management thinking - Taylorism. Crafted by Frederick Winslow Taylor in the early 20th century, Taylorism propagated the idea of scientific management, a method that dissected tasks into their simplest form, optimised them for utmost efficiency, and often scaled labour to elevate production levels.
For physical tasks and assembly lines, Taylor's principles worked wonders, revolutionized industries and significantly enhanced production capabilities.
Picture the iconic assembly lines of the early automotive industry, where each individual was a cog in a vast mechanical production machine. Every added worker, assigned to weld, assemble or inspect, directly increased the units rolling off the line. Thus, when faced with increased demand, the logical response was to simply insert more human cogs into this mechanical symphony, to amplify output.
However, the transition from rivets and wrenches to software development introduces a new set of variables into our equation. Software development, unlike assembly lines, isn't a straightforward repetitive sequencer task that benefits linearly from additional hands. It's a complex, often abstract, act of problem-solving, creativity and intricate collaboration. Part science, part art.
And as we pivot from mechanical to digital, from tangible to intangible, the straightforward "more hands, more work" equation from our industrial past has to be questioned.
And one of the best examples of this is the book The Mythical Man-Month by Fred Brooks. Within the book, Brooks illuminates a counter-intuitive principle: Adding manpower to a late software project makes it later.
The Perpex Manager may ponder, how could that possibly be?
In the realm of software development, each new developer added to a project introduces a myriad of new interactions, communication channels, and potential for misunderstanding. Unlike the clear, repetitive tasks on our historical assembly lines, software development demands a deep understanding and synchronization across team members regarding the project's architecture, code base, and forward trajectory.
In the short term of adding a new developer, we have the overhead of recruitment and onboarding.
Recruitment itself is no trivial venture. Sifting through candidates, aligning skill sets, and ensuring a cultural fit demands substantial time and financial investment.
And once recruited, any new developers require an immersion into the current project's depths, understanding its architectures, deciphering the codebase, and synchronizing with the existing team's rhythms and methodologies.
Onboarding new developers is not merely about handing them a wrench and placing them on the assembly line, but involves steeping them in the project's complexities, its intricacies, and its nuanced challenges. It's a time-consuming process, where the existing team often needs to divert their focus to integrate the newcomer, inadvertently slowing down the momentum even further.
It's really not uncommon to have to allow 3-6 months for a new developer to get up to speed.
But it's not just that short-term impact. There is a longer-term impact of a larger team. As the teams grow, the lines of communication, the communication channels, don't just add up, they multiply, exponentially amplifying the complexity of maintaining synchronized, coherent progress.
To illustrate this, let's consider a simple team of two. There is a single channel of communication between those two. It's easy for those two to communicate. It's easy to synchronise the work. It's easy to be able to work together.
If we add another developer, so we have a team of three, we now have three channels of communication, one between each pairing of those three team members. Again, that's probably within the realms of practicality in terms of communication and having to synchronise across the team.
With a team of 4, those channels jump to 6. With a team of 5, those channels jump to 10. In a team of 10, we have 45 different communication channels.
Each of those additional communication channels applies an overhead, a communication tax if you will, in the maintaining that synchronised coherent understanding within the team.
And, for the absence of doubt, while I have approached this topic by talking about "more developers", it is not just the adding of software developers to the team that causes this multiplication in communication channels. It's anyone that is working as part of the team, regardless of their discipline - be it a tester, a designer, a delivery manager, or anyone else, they all add to that complexity in maintaining that synchronised, coherent understanding within the team.
Brooks's insights, albeit decades old, reverberate with poignant relevance even today. In countless projects across the globe, the ill-timed influx of developers has led not to the envisioned acceleration, but instead a deceleration, entwining projects further into the quagmire of delays, miscommunications and huge overheads.
It's back to that muscle memory that tells us that if two developers produce X amount of output, four developers should naturally produce double, right?
However, as Brooks has shown us, every additional developer exponentially increases communication channels, coordination needs, and potentially diverges from the unified vision, diluting the anticipated linear increase in output.
The very cohesion that has once enabled a small team to work with agility, now becomes threatened by the operational tax of additional interactions, meetings and managerial overheads.
And with each layer of communication, the risk of misalignment, misinterpretation and misdirection surges, subtly eroding any anticipated gains from the increased manpower.
This is not mere theory. Numerous studies and project postmortems within software development industry have echoed these truths, painting a picture where the hidden costs of scaling a team frequently overshadowed the envisaged benefits.
Let's move on from the pitfalls and the dangers, and explore some situations where adding developers to a project isn't merely viable, but indeed advantageous. For while the axiom of "more is not always better" holds true, there exists a nuance. Certain conditions and contexts is where escalating a troop count can indeed amplify the rhythm and momentum of a software development project.
Firstly, consider the early stages of a project. In the nascent phases, where the foundations are still being laid and the architectural blueprints are being drawn, introducing new developers can facilitate a division of focus. Crafting multiple components in parallel, enhancing the speed and efficiency of initial project development cycles without entangling too many wires of communication and coordination.
Secondly, in specialised tasks, a proficient niche expert can make a world of difference. If your team is crafting a multifaceted application and encounters a segment requiring specialised knowledge, say, blockchain integration or artificial intelligence modelling, adding a developer with that specific expertise can streamline that proportion of the project, ensuring accuracy and efficiency without the trial and error that comes with unfamiliar terrain.
Next, when projects are clearly modular, with components that could be developed somewhat independently before integration, additional developers can work on separate modules without excessive amplification of the communication and coordination overhead. Think of it like constructing separate parts of a spaceship, each module crafted with excellence in different workshops, ready to be assembled into the final construct.
Additionally, scenarios with scalable teams wherein management structures, communication protocols and development practices are already formulated to accommodate team scaling, adding developers can be seamless. This requires a mature management and an organisation structure capable of assimilating new developers without hampering the ongoing momentum.
It is crucial, however, not to view these scenarios as carte blanche for unchecked team expansion. Even under these circumstances, mindful strategic scaling, ensure each added developer is not merely a number, but a carefully considered chess piece, positioned for optimal impact.
And this brings us back to one of the most powerful principles in modern software development, the Small Agile Team.
In a world where "bigger is better" often echoes as a guiding principle, the prowess of small agile teams illuminates an alternative path, especially in the nuanced landscape of software development.
One can't help but recall Jeff Bezos 2 pizza rule, which posits that the teams should be small enough to be fed by 2 pizzas. The underpinning philosophy here isn't culinary, but rather a profound recognition of the dynamic agility, enhanced communication and potent focus that small teams inherently possess.
A smaller team focuses a streamlined communication channel, reduces the probability of miscommunication, and ensures that coordination efforts are succinct and effective. The proverbial shift can change its course, with a nimbleness that larger teams might struggle to emulate.
Moreover, in the delicate ecosystem of software development, where creativity, problem-solving and innovation are pivotal, the intimate environment of a small team can nurture a safe, collaborative space where ideas are freely exchanged and individual contributions are palpably impactful. They become tight-knit units where each member doesn't just perform a function. They play a pivotal role in shaping the journey and destination of the project. There's an intrinsic ownership and accountability that permeates through the team, enriching not just the work environment, but also enhancing the quality integrity of the final product.
Moreover, small teams, when equipped with a diverse skill set, can operate as self-contained units, capable of independently navigating through the various phases and challenges of the development cycle. This autonomy translates to reduced management overhead and allows for parallel progression in multiple small teams if they are deployed across different components or projects.
However, the potency of small, agile teams is not merely in their size, but in their alignment. A shared vision, clear roles and a harmonious blend of skills and personalities that catalyse rather than conflict.
So, if we still desire to go faster, but adding more developers isn't the answer, what other options do we have? How do we accelerate development without amplifying the developer count? How do we resolve this seemingly counter-intuitive problem?
Firstly, embrace the optimization of existing processes. A meticulous audit of your current development, communication and coordination processes can unveil hidden bottlenecks and inefficiencies. Employ methodologies such as Agile or Lean, and utilize tools that foster smoother collaboration and task management. Streamlining these processes can markedly elevate the output of your existing team without necessarily adding additional hands-on to deck.
Next, delve into skill enhancement. Investing in the continual growth and upskilling of current developers can unveil a potential within the same team. By nurturing an environment of learning and adaptation, developers can embrace new technologies, methodologies and strategies, subsequently elevating their productivity and the overall team output.
Next, look towards automating repetitive tasks. Identify areas within development and testing phases that are repetitive and prone to manual error. By implementing automated testing, continual integration, and continual deployment, the team can focus their intellect and creative energies on problem solving and innovation, while the automated systems handle the routine tasks.
Next, recognise the potency of shared purpose. Employing strategies that align tasks and outcomes clearly, aim to harmonise teams' efforts as much as possible. Ensuring that each developer is working on tasks and they are in sync with the desired outcomes, enhances efficiencies and negates wasted effort on misaligned tasks.
Next, foster a culture of innovative problem solving. By embedding a mindset that values innovative approaches to challenges within the development cycle, developers may devise new strategies, tools or code that optimises the current development process, potentially reducing the time and effort required to reach milestones.
Lastly, invest in maintaining high morale. The psychological and emotional state of your team significantly influences their productivity and creativity. Ensuring a healthy work-life balance, recognizing and rewarding efforts, and cultivating a positive, inclusive work environment can optimize the output of your existing team, often outstripping what could be achieved by merely adding more developers.
As we conclude this episode, let's reflect on the knowledge and strategies we've gone through today.
While we've explored the dichotomy of more developers vis-a-vis effective development, we've ventured through the history of why more hands on deck is so ingrained within management principles, and explored the modern day paradox where adding more developers doesn't always equate to swifter project completion.
The learnings from the "Mythical Man-Month" penned by Fred Brooks reverberate for our discussions, underscoring the nuances that software development isn't merely a task of manual labor, but a complex choreography of collaborative intellect communication and coordinated efforts
We have also explored scenarios where indeed adding new developers can be a beneficial strategy, as long as we are respecting the conditions and boundaries within which such expansions yield fruitful outcomes.
We've honoured the potential force of small Agile teams, acknowledging the vibrant energy, innovation and nimble adaptability that they bring to our projects.
And we've provided some suggestions that can accelerate software development without adding developers. We've unearthed strategies that can empower us to optimise, innovate and enhance our existing teams and processes, ensuring that every ounce of intellect and creative prowess is harnessed effectively.
As we close this episode, consider the following:
- Evaluate continuously. Regularly assess your team's dynamics, project progress and efficacy of deployed strategies, ensuring alignment with project goals and team well-being.
- Optimise strategically. Implement changes and optimisations with foresight, ensuring that they are well-communicated, gradual and are simulated within the team's workflow with minimal disruption.
- Invest intelligently. Whether it's in technology, methodologies or your team, ensure every investment is aimed at amplifying the existing strengths and mitigating the challenges, rather than merely expanding in size.
- Communicate effectively. Foster an environment where communication is transparent, regular and multidimensional, ensuring every team member is aligned, heard and valued.
The journey through software development management is intricate and multifaceted. However, with strategic thinking, continuous learning and mindful implementation of practices, the path to optimal ROI and team satisfaction becomes clear, allowing us to steer our projects towards successful horizons with confidence and expertise.
This would normally be the part where I thank you for listening to the episode, and tell you I look forward to speaking to you again next week. However, I'll be planning to take some time off. I'll be taking time to prepare some great content to take us up to the 200th episode.
I'll start next year off with a review of Estimation in Software Development. Back in January of this year, in episode 160, I made a commitment to revisit my long-held beliefs on Estimation in Software Development, and over the year I've been researching the subject extensively, and would love to share my thoughts with you.
I would like to follow that with a look at the Kanban System. Many of you might be aware of the Kanban boards often used to visualise the progression of tasks, left to right, from backlog to doing to done. But the Kanban System goes much deeper than that, and I feel there is a lot to learn from it.
I'll also be revisiting the state of AI Coding Assistants and the use of AI in general. With such a fast moving subject, I can see me dipping into it often within the podcast as the field matures and I personally learn more about it.
And as always, I'll bring you advice on how to achieve the best ROI from your software development efforts.
Thank you for supporting my podcast and taking the time to listen. While I doubt I'll have anything other than a niche audience, I do appreciate the time spent listening, when there are so many other distractions competing for your time. So again, thank you.
I'll be back with new episodes in early February, so I look forward to speaking to you again then.

The Better ROI from Software Development podcast is a short (10-15 minutes) weekly podcast aimed at non-technical CXO/ Managers - advising them on how to get better results from their software development efforts.
The podcast format is just me as the narrator, with no guests, actors or music.
Occasionally I will have an episode with explores something that may previously been considered good or common practice, but is actually causing dysfunctional, and unexpected, results in modern software development - and thus would be bad for ROI.
Draft an outline for an episode titled "Bad for ROI: More developers". This episode wants to address the muscle memory approach of adding more developers if software development work is not progressing as quickly as needed.
The episode should look to cover - why the call is often made for "more development" and historical background, why "more development" comes at a cost to development progress (both in terms of short term impacts from recruitment/ onboarding and long term impacts of increased team size leading to more overhead in coordination).
The episode should explore situations when adding more developers may be beneficial - as well as how commonly adding more developers has the un-initiative outcome of slowing the team down.
Where possible, include references to notable books, articles or surveys on the subject

"As we leap forward from the industrial era to our present-day digital epoch, we find ourselves encased in a world where 1s and 0s sculpt our realities. The assembly lines are now virtual, the products intangible, and the production dynamics intricately complex. Welcome to the era of software development, where our historical 'more hands, more work' theory is confronted by a perplexing paradox: The Myth of Manpower in Software Development.
This myth was eloquently encapsulated by Fred Brooks in his seminal work, 'The Mythical Man-Month.' Brooks bravely illuminated a counterintuitive principle: Adding manpower to a late software project makes it later. The perplexed manager might ponder, 'How could that possibly be?'

And let's not forget, as the team grows, the communication channels don't just add up; they multiply, exponentially amplifying the complexity of maintaining synchronized, coherent progress. Imagine trying to orchestrate a symphony where every additional musician didn't just communicate with the conductor, but also needed to coordinate with every single other musician in real-time. The cacophony can, without diligent management, drown the symphony's harmony.
Brooks' insights, albeit decades old, reverberate with poignant relevance even today. In countless projects across the globe, the ill-timed influx of developers has led not to the envisioned acceleration, but instead, a deceleration, entwining projects further into the quagmire of delays, miscommunications, and burgeoning overheads.

"Embarking further into our exploration of the complexities within software development, we now uncover the concealed icebergs that lurk beneath the decision to scale development teams. At first glance, the strategy appears as straightforward as deploying extra ships to hasten a treasure hunt. However, unlike our nautical analogy, in the realms of software, the treasure map is continually morphing, and every added ship - or in our case, developer - brings with them a wave of hidden, often unexpected costs.
In the short-term horizon, the first wave crashes in: Recruitment and Onboarding. Recruiting itself is no trivial venture. Sifting through candidates, aligning skill sets, and ensuring a cultural fit demand substantial time and financial investments. And once aboard, new developers require an adept immersion into the current project's depths - understanding its architecture, deciphering the codebase, and synchronizing with the existing team's rhythm and methodologies. This onboarding is rarely swift, invariably siphoning away precious resources and time from existing team members, potentially decelerating progress rather than accelerating it.
As we gaze further into the long-term vista, the seas become increasingly tumultuous. The theory which might be lurking in our managerial subconscious tells us that if two developers produce X amount of output, four developers should naturally produce double, right? Ah, if only the seas of software development were so serene! Every added developer exponentially increases communication channels, coordination needs, and potential divergence from the unified vision, diluting the anticipated linear increase in output.
The very cohesion that once enabled a smaller team to navigate through the project with agility now becomes threatened by the swelling tides of additional interactions, meetings, and managerial overheads. And with every added layer of communication, the risk of misalignment, misinterpretation, and misdirection surges, subtly eroding the anticipated gains from the increased manpower.
It is not mere theory; numerous studies and project post-mortems within the software development industry have echoed these truths, painting a picture where the hidden costs of scaling teams frequently overshadow the envisioned benefits.
Thus, as we steer our managerial ships through the intricate waters of software development, recognizing and navigating these hidden costs becomes paramount to safeguarding our projects against unforeseen delays and burgeoning budgets.

Can you provide an example of how the communication channels expand exponentially - with 2 developers - there is 1 channel, with 3 developers there is 2 channels
ChatGPT:
Actually, the explanation provided in your example doesn't accurately represent how communication channels increase exponentially with each additional team member. The formula to calculate the number of communication channels between team members is C=nx(n-1)/2, where C is the number of communication channels and n is the number of team members.
Let's explore a few examples to illustrate this:
With 2 developers, there's 1 communication channel (as per your example). Applying the formula: C=2x(2-1)/2=1
When a 3rd developer is added, communication becomes more complex: C=3x(3-1)/2=3
Every developer needs to communicate with every other developer to ensure they're synchronized, leading to 3 communication channels: Developer 1 with Developer 2, Developer 2 with Developer 3, and Developer 1 with Developer 3.
Now, with 4 developers, the complexity increases further: C=4x(4-1)/2=6
Thus, each additional developer does not merely add one new communication channel but creates multiple new ones as they need to coordinate with each existing team member.
Jumping to 5 developers showcases the exponential growth even more clearly: C=5x(5-1)/2=10
This pattern illustrates the challenges and complexities introduced to project management and team coordination as more individuals (and thus, communication channels) are added. The significant increase in communication channels with each added developer sheds light on the potential for miscommunication, delays, and administrative overhead, which are crucial aspects to consider when determining team size in software development.
User:
What would the number be with 10 developers?
ChatGPT:
To calculate the number of communication channels (C) with 10 developers (n), we can use the formula: C=nx(n-1)/2
Substituting C=10 and n=10 into the formula:
C=10x(10-1)/2
C=10x9/2
C=90/2
C=45
So, with 10 developers, there would be 45 different communication channels. This illustrates the escalating complexity and potential for miscommunication as team size increases, underscoring why simply adding more developers to a project might not always translate to increased productivity or faster delivery. This kind of exponential growth in communication channels can substantially amplify coordination challenges and project management overhead as the team grows.

For while the axiom 'More is not always better' holds true, there exists a nuance; certain conditions and contexts where escalating the troop count can indeed amplify the rhythm and momentum of a software development project.
Firstly, consider the Early Stages of a project. In the nascent phases, where the foundations are still being laid, and the architectural blueprints are being drawn, introducing more developers can facilitate a division of focus - crafting multiple components in parallel, enhancing the speed and efficiency of the initial development cycle, without entangling too many wires of communication and coordination.
Secondly, in Specialized Tasks, a proficient, niche expert can make a world of difference. If your team is crafting a multifaceted application and encounters a segment requiring specialized knowledge - say, blockchain integration or artificial intelligence modeling - adding a developer with that specific expertise can streamline that portion of the project, ensuring accuracy and efficiency without the trial and error that comes with unfamiliar terrain.
Next, when projects are Clearly Modular, with components that can be developed somewhat independently before integration, additional developers can work on separate modules without excessively amplifying the communication and coordination overhead. Think of it like constructing separate parts of a spaceship - each module crafted with excellence in different workshops, ready to be assembled into the magnificent final construct.
Additionally, scenarios with Scalable Teams wherein management structures, communication protocols, and development practices are already formulated to accommodate team scaling, adding developers can be seamless. This requires a mature managerial and organizational structure, capable of assimilating new developers without hampering the ongoing momentum.
It's crucial, however, to not view these scenarios as a carte blanche for unchecked team expansion. Even under these circumstances, mindful, strategic scaling - ensuring each added developer is not merely a number but a carefully considered chess piece, positioned for optimal impact - is paramount.
In our upcoming segment, we will weave together the threads of insights from our journey today, crafting a tapestry of guidelines and strategies, to navigate through the decision-making labyrinth that envelops the scaling of development teams, ensuring every move is in harmony with our ultimate quest: Enhanced ROI and project success."

Segment 5 Script: The Power of Small, Agile Teams
[Pause for a moment before speaking]
"Underneath the sprawling umbrellas of software development projects, a subtle, yet powerful force perpetually pulses: The small, agile team. In today's segment, we delve into the unassuming might of these compact units, exploring how, under the right conditions, they can be the catalysts propelling projects forward with an unmatched, vibrant energy.
In a world where 'bigger is better' often echoes as a guiding principle, the prowess of small, agile teams illuminates an alternative path, especially in the nuanced landscape of software development.
One can't help but recall Jeff Bezos's 'Two-Pizza Rule' which posits that teams should be small enough to be fed by two pizzas. The underpinning philosophy here isn't culinary but rather, a profound recognition of the dynamic agility, enhanced communication, and potent focus that small teams inherently possess.
A smaller team fosters a streamlined communication channel, as we've mathematically explored in our earlier segments, reducing the probability of miscommunications and ensuring that coordination efforts are succinct and effective. The proverbial ship can change its course with a nimbleness that larger teams might struggle to emulate.
Moreover, in the delicate ecosystems of software development where creativity, problem-solving, and innovation are pivotal, the intimate environment of a small team can nurture a safe, collaborative space where ideas are freely exchanged, and individual contributions are palpably impactful.
They become tight-knit units where each member doesn't just perform a function but plays a pivotal role in shaping the journey and destiny of the project. There's an intrinsic ownership and accountability that permeates through the team, enriching not just the work environment but also enhancing the quality and integrity of the final product.
Furthermore, small teams, when equipped with a diverse skill set, can operate as self-contained units, capable of independently navigating through the various phases and challenges of the development cycle. This autonomy translates to reduced managerial overhead and allows for parallel progression if multiple small teams are deployed across different components or projects.
However, the potency of small, agile teams is not merely in their size but in their alignment - a shared vision, clear roles, and a harmonious blend of skills and personalities that catalyze rather than conflict.
As we sail towards the horizon of evolving project landscapes, recognizing and harnessing the power of small, agile teams can be the wind in our sails, propelling us towards successful, efficient, and innovative software development, ensuring that our journey through the digital seas is both prosperous and fulfilling."
