Understanding the impact of technical debt on the capacity and velocity of teams and organizations: Viewing team and organization capacity as a portfolio of real options

Understanding the impact of technical debt is critical to understanding a team´s velocity. For organizations with multiple teams and products, the impact of technical debt combines non-linearly to impact the organization´s velocity. We can think of the capacity of a team as a portfolio. Not all of that capacity can be invested in new features or defect fixing, without incurring negative consequences. A portion of the team´s capacity needs to be invested in the ongoing management and reduction of technical debt. This paper describes a simple technique for visualizing, quantifying and tracking a team´s technical debt as a portion of their overall capacity investment. The knowledge and insights gained through this technique help with better capacity planning, improved forecasting, and helps to justify the business case for investing in managing and reducing technical debt.
