When it comes to building a startup, what is the right team size for a software development project? The matter of creating the right team size appears on the agenda each time a new team needs to be organized or an existing team is being assessed. 


On the one hand, quality is always more essential than quantity. But on the other hand, the perfect team needs to have enough resources to be productive and cover all phases of the development life cycle. 


To help you decide on the optimal software development team size, we’ve gathered useful tips from our experts in this article. Enjoy!


The Importance of Software Development Team Size

The recent findings by ResearchGate state that the development platform, programming language, and team size are key factors influencing the productivity of software development. We’ll focus on the last one to show you how human resources are vital to project success.


Any project presupposes teamwork and can’t be completed effectively by one person. Your IT project might need several people working on it. However, if the team has too many members there is a hazard for the productivity level of each member to go down with the team’s growth. This theory has been called “Social Loafing” or the “Ringelmann Effect”.

The Ringlemann effect theory stipulates that a company can achieve much more with a greater number of team members, but the individual members of the larger team are less productive than their counterparts in smaller teams. According to this theory, the individual efforts of each group member decrease due to the larger workforce.

The “Ringelmann Effect” has been proven in the course of research. It illustrates the dynamics of team size. Through a series of experiments involving large groups of people pulling a rope, Maximilien Ringlemann concluded that individual contributions were decreasing for every person who is added beyond 5-6 people who pulled a rope.


Consequently, some employees might want to weaken their work resolve at their workplaces thinking that their lack of effort will be complemented by the overall team’s greater effort. Others won’t simply work hard as they did before because their efforts may be unacknowledged. Even if the company increases in overall output, it’s not where it should be when their individual productivity level decreases.


In the case of software development team size, the “Ringelmann Effect” is avoided by keeping the number of professionals to fill all necessary roles to a minimum. A competent PM selects the exact number of specialists for an IT project, oversees their work, and motivates the team to mitigate the “Ringelmann Effect.”


Now let’s go further with the factors you should consider when determining the right software development team size.


Factors to Consider When Building a Perfect Development Team

Before starting a hiring process, think about the key factors influencing the number of specialists required for the particular project. Below, we’ve gathered the most valuable things to consider when deciding on the software development team size. 


Project complexity

The project scope and complexity define the number of tasks, specialists, and resources. That’s why you need to assess the scope of your project first and then decide on the team size required to cover every stage. 


For example, when you start a project from scratch, you’ll need a bigger team rather than when you need some redesign or rebuilding. Project complexity may also depend on the industry and type of software. 


Balance in skillset

How many people do you need to fill the unique roles and responsibilities on the team? You should make sure that there is no skills gap in your team. On the other hand, too many people with the same skills in your team might lead some people to loaf and be less productive. 


Thus, try to keep a balance between required skills and avoid duplication of competencies. An employee skills matrix is a great way to help teams distribute the skills among specialists the right way. Here is an example of such a matrix:


Project’s timeframe

Work that should be completed quickly calls for a larger team with more hands on deck to do all the necessary work on time. Longer-term projects can be best accomplished by smaller teams as they tend to be more cohesive and less friction-oriented. 


Typically, people are more open to sharing their joys and pains about their work in a small group environment. Additionally, such teams are easier to monitor and are the most active “rope-pullers.



Budget capacity

Your software development team size may greatly depend on your budget. If your project runs on a shoe-string budget, we recommend you to focus on the alternative employment models rather than hiring fewer in-house specialists for your project. 


For example, you can choose between freelance, part-time, contract, or outsourcing options. Based on our deep expertise in gathering dedicated development teams, we can say that outsourcing is one of the best-working and reliable employment models in the software development industry today. You can hire the brightest IT minds from any corner of the world according to your budget, goals, and required skill set.



What is the Ideal Size of Development Teams?

In most cases, software development teams work according to Scrum, Kanban and other Agile methodologies. Scrum is an iterative and incremental agile software development method for managing software projects and product or application development. Moreover, Scrum is the agile project management framework that is widely used in software development. 


Agile has mainly two roles within it: primary or required and optional roles that depend on the project needs. For example, a software development team may include, but not be limited to, the following roles:

 

  • Project manager (PM)
  • Product manager 
  • Business analyst (BA)
  • Backend developers
  • Frontend developers
  • Mobile developers
  • UI/UX designer
  • Tech lead
  • Quality assurance (QA) engineers/QA automation engineers


Optionally, if your project requires, you might also need the help of:

  • Solution architect
  • DevOps engineer
  • VR designer
  • 3D modeler
