Dans le domaine de la gestion de projet, une estimation et un contrôle efficaces des coûts sont primordiaux pour assurer le succès du projet. L'un des outils clés utilisés à cette fin est le Coût budgétaire du travail prévu (BCWS), un élément essentiel du cadre du système de contrôle des coûts et des délais (C/SCSC).
Qu'est-ce que le BCWS ?
Le BCWS représente le coût total budgétisé pour tous les lots de travail, les lots de planification et les éléments similaires prévus pour être terminés dans une période donnée. Cela comprend le coût des lots de travail en cours, ainsi que le coût du niveau d'effort et de l'effort réparti alloué pour cette période.
Comprendre les composants :
Calcul du BCWS :
Le BCWS est calculé en additionnant les budgets de tous les lots de travail, les lots de planification, le LOE et l'effort réparti prévu pour une période donnée. Par exemple, si un projet comporte 5 lots de travail avec un budget total de 100 000 $ prévu pour être terminé en un mois, le BCWS pour ce mois serait de 100 000 $.
Importance du BCWS :
Le BCWS sert de base pour mesurer les performances du projet. Il fournit une compréhension claire des dépenses prévues pour une période donnée, permettant aux chefs de projet de :
Intégration avec d'autres indicateurs :
Le BCWS est souvent utilisé conjointement avec d'autres indicateurs clés de performance (KPI) tels que :
Ces indicateurs, ainsi que le BCWS, forment la base de l'analyse de la variance des coûts et de l'analyse des performances de l'échéancier, offrant une image complète des progrès et des performances du projet.
Conclusion :
Le BCWS est un élément essentiel d'une gestion efficace des coûts de projet. En fournissant une référence claire pour les dépenses prévues et en facilitant l'analyse des performances, il permet aux chefs de projet de prendre des décisions basées sur des données, de suivre les progrès et de garantir la réussite du projet dans les limites du budget.

Scenario:
You are managing a software development project with a total budget of $500,000. The project is divided into 4 work packages:
The project schedule is as follows:
Task: Calculate the BCWS for each month of the project.
**Month 1:** BCWS = $100,000 (Work Package 1) **Month 2:** BCWS = $300,000 (Work Package 1 + Work Package 2) **Month 3:** BCWS = $400,000 (Work Package 1 + Work Package 2 + Work Package 3) **Month 4:** BCWS = $500,000 (Work Package 1 + Work Package 2 + Work Package 3 + Work Package 4)
This chapter delves into the different techniques and approaches for calculating Budgeted Cost of Work Scheduled (BCWS).
