Dans le monde dynamique de la gestion de projet, la navigation dans la complexité est la clé du succès. Un outil puissant qui aide les gestionnaires de projet à planifier et à programmer efficacement des projets complexes est la **Technique d'Évaluation et de Révision du Programme (PERT)**.
Développée dans les années 1950 pour le programme de missiles Polaris, la PERT est une technique de planification et de gestion de projets complexes avec des durées d'activité incertaines. Sa valeur principale réside dans la fourniture d'un cadre pour :
Comment fonctionne la PERT :
Avantages de l'utilisation de la PERT :
Limitations de la PERT :
En conclusion :
La PERT est un outil précieux pour la gestion de projets complexes, mais il est essentiel de comprendre ses limites. Lorsqu'elle est utilisée efficacement, la PERT peut aider les gestionnaires de projet à créer des plans robustes, à atténuer les risques et à atteindre les objectifs du projet dans les délais prévus.

Scenario: You are the project manager for a new software development project. The project has been broken down into the following tasks, with their estimated optimistic (O), pessimistic (P), and most likely (M) durations:
| Task | O (days) | M (days) | P (days) | |---|---|---|---| | Task A | 5 | 8 | 12 | | Task B | 3 | 5 | 7 | | Task C | 2 | 4 | 6 | | Task D | 6 | 10 | 14 | | Task E | 4 | 7 | 10 | | Task F | 1 | 2 | 3 | | Task G | 3 | 5 | 7 |
