A project manager has commissioned a design study from a consulting firm to investigate a number of alternatives. The project manager has a strict policy on the cost of the study and has established a number of cost triggers and trend analyses.
Which tool is the project manager using?
The project manager is using S-curve analysis. S-curve analysis is a tool commonly used in project management to monitor the cumulative cost of a project over time and identify cost triggers and trends. It allows the project manager to plot cumulative costs and track actual expenditure against planned expenditure, thereby providing insights into cost performance and potential deviations. This aligns with the description of the project manager using cost triggers and trend analyses to manage the project costs.
B. S-curve analysis: The tool that best fits this description is the S-curve analysis. Cost Monitoring: S-curve analysis is commonly used in project management to monitor the cumulative cost of a project over time. It helps in tracking actual expenditure against planned expenditure and identifying any deviations early. Trend Analysis: S-curve analysis involves plotting cumulative costs over time, which allows the project manager to perform trend analysis and understand the progression of costs. This can help in forecasting future expenditures and identifying potential cost overruns. Cost Triggers: By establishing cost triggers, the project manager can set specific points on the S-curve where actions need to be taken if costs exceed certain thresholds. This proactive approach helps in maintaining control over the project budget.
Contrat de temps et de matériaux (T&M) : C'est un type de contrat de projet qui permet de payer le fournisseur en fonction du temps travaillé et des matériaux utilisés, plutôt qu'un outil de gestion de projet pour surveiller les coûts et les tendances. Analyse de la courbe en S : Cette analyse est utilisée pour visualiser la progression du projet par rapport au temps et au budget, mais elle ne traite pas spécifiquement des déclencheurs de coûts ou des analyses de tendances en tant que méthodologie complète. Carte de contrôle : Utilisée principalement dans la gestion de la qualité pour surveiller les variations de processus, elle ne traite pas de la gestion des coûts de projet ou des tendances globales du projet.
Le chef de projet utilise l'outil "Valeur acquise (EV)" (option C). La valeur acquise est une méthodologie de gestion de projet qui mesure la performance et l'avancement d'un projet en termes de coûts et de calendrier. Elle permet au chef de projet de comparer le travail effectivement accompli par rapport au plan initial et de déterminer si le projet est en avance, en retard, en dessous ou au-dessus du budget. Les déclencheurs de coûts et les analyses de tendances mentionnés dans la question sont des éléments typiques de cette approche, qui utilise des indicateurs comme le Coût Réel (CR), la Valeur Planifiée (VP), et la Valeur Acquise (VA) pour fournir une vision claire de l'état du projet en temps réel.
S-curve shows if the project is over or under budget
Tracking Cost Performance, Triggers and Trend Analysis. Control Cost is not a core tool it can be used in conjunction with EV.
A control chart is a statistical tool used for monitoring and controlling processes. It helps identify trends, patterns, and variations in a process over time. In this case, the project manager is using cost triggers and trend analyses, which align with the purpose of control charts to monitor and control the cost aspects of the project.
S-Curve is used to track costs.
Time and Material Contract as Control chart is sued to control quality and not budget
With a time and materials contract, instead of quoting a fixed price for the entire project, a contract will describe the rough scope of the job along with a quote for a fixed hourly wage plus the cost of materials. The contractor might also include a maximum price for the project — commonly called a “not-to-exceed” clause — as a guarantee to protect the client against runaway costs.
A control chart is a tool used in project management for monitoring and controlling the performance of a process. It is particularly useful for managing costs and other project variables. Control charts help project managers identify trends, variations, and potential issues in the project, allowing them to take timely corrective actions. The use of cost triggers and trend analyses aligns with the principles of control charts in tracking and managing project costs.
