A working definition from the RGM marketing glossary. Document tracking active issues. Term : Issue Log Field : Product Management Category : Growth & Lifecycle ## The short definition Pick one definition.Issue Log means a lifecycle concept. The value is in a shared, precise definition, not in knowing the word. Document tracking active issues. In product management, this concept guides how products are scoped, prioritized, built, measured, and iterated. It typically affects roadmap decisions, feature trade-offs, and definitions of success. Issue Log sits in Growth & Lifecycle; it is a lifecycle concept. Define it once and the reporting holds together. ## How it operates Read that twice.Issue Log produces value through how it is applied. Change the inputs and the right use of it changes too. Issue Log is not a switch you flip. It names a moving idea, and the way it plays out shifts with the setup. A lean team running one paid channel applies Issue Log differently than a brand running ten. Use Issue Log loosely and teams pull apart; pin it down and the math lines up. The working rule is plain. Agree what Issue Log covers first, then act on it. Skip that order and Issue Log loses its shared meaning, and two teams end up measuring two different things. Read that twice. ## When to reach for it Read that twice.Use Issue Log when it changes a choice. If it is not driving a decision, it is vocabulary, not leverage. Use Issue Log when it changes an outcome. For growth & lifecycle teams, that tends to be three recurring moments. With no choice live, Issue Log is good to know, not to chase. 1. **Setting budget.** Issue Log points to where the next dollar should go. 2. **Choosing a metric.** Issue Log checks that the figure is not just noise. 3. **Comparing options.** Issue Log keeps a head-to-head from fooling the reader. ## A worked example Read that twice.The example below traces Issue Log through a real Duolingo scenario, with real limits and a number to read at the end.
