Comment évaluez-vous le retour sur investissement de la programmation en binôme ?

Another great way to assess the value of pair programming its to evaluate people's growth over time. The main benefit of pair programming is that it speeds up people's learning process so results should be quickly seen in individual growth. This can easily be done with a simple 1->10 scaling system on different skills like: domain knowledge or specific technology proficiency tracked over time for each individual in the team.

Think beyond numbers – the collaboration in pair programming boosts team morale and sparks innovation. The unquantifiable gains in shared problem-solving and creativity significantly contribute to project success.

Evaluating the ROI (Return on Investment) of pair programming from a Scrum Master's perspective involves both quantitative and qualitative analysis.Start by defining what you expect to achieve through pair programming. Common goals might include improving code quality, reducing defects, accelerating knowledge transfer, or enhancing team collaboration.One way to assess the value of pair programming is to compare its costs and benefits. The main cost of pair programming is the increased labor hours, as two programmers work on the same task instead of working on different tasks. Another way to evaluate the value of pair programming is to calculate its return on investment (ROI). ROI is a continious process.

Pairing promotes improved quality, faster releases, higher competence particularly with domain knowledge. Less turnover as colleagues feel valued, trusted, and empowered. The list goes on. It is not a direct ROI, it supports a stronger longterm ROI.

Nearly every programming project is evaluated based on the timeliness of deliverables and quality. The latter encompasses aspects such as user experience, robustness, and responsiveness. If you have a baseline of past programming projects where pair programming was not implemented, you can compare those with current projects that utilized pair programming — focusing on dimensions of timeliness and quality.

A cost-benefit analysis of pair programming can help evaluate its effectiveness by weighing the potential advantages (benefits) against the associated drawbacks (costs). This approach helps teams and organizations make informed decisions about whether or when to use pair programming based on their specific context and goals.

Return on Investment (ROI) in pair programming refers to the balance between the costs invested in having two developers work together and the value or benefits gained from that collaboration. ROI in pair programming is often assessed not just in financial terms but also in terms of productivity, quality, knowledge sharing, and long-term organizational impact.To effectively measure ROI, a mix of quantitative and qualitative metrics should be considered like productivity metrics, defect metrics, onboarding and training coasts, retention metrics, Quality and Code Maintenance Metrics. The long-term ROI is often favorable when factoring in the reduction in technical debt, faster onboarding, and knowledge sharing.

Look at the bigger picture – consider long-term benefits like reduced technical debt. Although trickier to measure initially, focusing on code maintainability and scalability adds substantial value over time.

Factor in the learning curve – while pair programming may seem less efficient initially, as teams become proficient, productivity increases, positively influencing the break-even point.

This is where pair programming triumphs. Pair programming brings in many possibilities that would have normally not have been possible. It enables junior engineers to take on complicated sets of tasks along with senior engineers. Bringing in better quality and speed of development. Also, this can be one way to RAMP-up new folks on the team. Pair programming is a good way to improve collaboration and communication among junior engineers. Considering all these, a few metrics that showcase the qualitative view are: 1. # of bugs in changes by junior engg with and without a senior engg involvement 2. RAMP-up time of junior engg

Pair programming needs not only a Developpeur change of mindset, but also from a management point of view, where their trust their team to know how to resolve a problem. Management should seek the results, not how the results is made.

Pair programming requires a mindset shift for the developers that adopt it: from individual impact to team impact, from delivering code to providing value, from individidual growth to "growth together".

When adopting pair programming, companies need to afford the team sufficient time to settle into the practice before trying to ascertain its costs and benefits. For developers used to working alone, pair programming could prove to be a steep learning curve and could initially lead to a dip in productivity as developers learn to adapt to the new collaborative way of working.

I don't think that this is practical... The problems associated with this are: 1.Limited Team Size. 2.0% redundancy. 3.Restriction of knowledge absorption. 4.Versioning problems It is better to go Solo. Amelia Earheart did that, didn't she?

If your customers are happier and you’re generating more revenue or improved your margins, I would say that’s a pretty good measure.
