Dans le domaine de la planification et de l'ordonnancement de projets, « activité planifiée » est un terme fondamental qui revêt une importance considérable. Il désigne **toute tâche ou élément de travail qui a été identifié et décrit dans un plan de projet, mais qui n'a pas encore commencé ou n'a pas été achevé avant une « date de référence » spécifique.** Cette « date de référence » est simplement un point dans le temps choisi comme référence, représentant généralement le présent ou un jalon particulier.

Chapter 1: Techniques for Identifying and Defining Planned Activities
This chapter focuses on the practical techniques used to identify and define planned activities within a project. Effective identification is the cornerstone of successful project planning.
Work Breakdown Structure (WBS): The WBS is a hierarchical decomposition of the project into smaller, manageable components. Starting with the overall project goal, the WBS progressively breaks it down into phases, deliverables, and ultimately, individual planned activities. Techniques like brainstorming, mind mapping, and decomposition methods are employed to create a comprehensive WBS.
Precedence Diagramming Method (PDM): PDM visually represents the dependencies between planned activities. Using nodes to represent activities and arrows to show dependencies, PDM clarifies the sequential relationships, allowing for a clear understanding of the project flow. This method helps identify critical paths and potential bottlenecks.
Critical Path Method (CPM): CPM is a project management technique that analyzes the sequence of activities to determine the shortest possible time to complete the project. By identifying the critical path – the sequence of activities with the longest duration – project managers can focus resources on these crucial tasks to minimize delays.
Program Evaluation and Review Technique (PERT): PERT is similar to CPM but incorporates uncertainty in activity durations by using optimistic, pessimistic, and most likely estimates. This produces a probabilistic estimate of the project completion time, providing a more realistic view of potential delays.
Activity Sequencing: Determining the order in which activities should be performed is crucial. This involves understanding dependencies, resource constraints, and logical sequencing to optimize the project schedule.
Effective Techniques Summary Table:
| Technique | Description | Strengths | Weaknesses | |----------------------|------------------------------------------------------------------------------------|-------------------------------------------------------------------------|---------------------------------------------------------------| | WBS | Hierarchical decomposition of the project | Comprehensive overview, clear scope definition | Can be time-consuming for large projects | | PDM | Visual representation of activity dependencies | Clear visualization of project flow, identification of critical path | Can become complex for large projects | | CPM | Analyzes activity sequence to determine shortest project duration | Focuses resources on critical path activities | Assumes deterministic activity durations | | PERT | Incorporates uncertainty in activity durations | Provides probabilistic project completion time estimate | Requires more data and is more complex than CPM | | Activity Sequencing | Determining the order of activities based on dependencies and resource constraints | Optimizes project schedule | Requires careful consideration of dependencies and resource limitations |
Chapter 2: Models for Representing Planned Activities
This chapter explores various models used to represent and manage planned activities. Selecting the appropriate model depends on the project's complexity and the information required.
Gantt Charts: These bar charts visually represent the schedule of planned activities, showing their durations, start and finish dates, and dependencies. Gantt charts are widely used for their simplicity and visual clarity.
Network Diagrams: These diagrams, such as those used in CPM and PERT, illustrate the relationships between activities, highlighting dependencies and the critical path. Network diagrams provide a more detailed view of the project's logical structure.
Milestone Charts: These charts focus on key milestones, providing a high-level overview of project progress. They are useful for tracking major deliverables and reporting to stakeholders.
Kanban Boards: Visual representation of workflow, useful for managing iterative projects and tracking progress of individual planned activities.
Model Selection Considerations:
The choice of model depends on factors like project size, complexity, team familiarity with the chosen model, and the need for detailed versus high-level information. For smaller, simpler projects, a Gantt chart may suffice. Larger, more complex projects may benefit from a combination of network diagrams and Gantt charts.
Chapter 3: Software for Managing Planned Activities

Microsoft Project: A widely used software for project scheduling and management, offering features like Gantt charts, resource allocation, and critical path analysis.
Asana: A collaborative work management platform that enables task assignment, progress tracking, and communication.

Software Selection Criteria:
When selecting software, consider factors like cost, ease of use, integration with other systems, scalability, features offered, and the specific needs of the project team.
Chapter 4: Best Practices for Managing Planned Activities
This chapter outlines best practices to ensure effective management of planned activities.
Chapter 5: Case Studies of Planned Activity Management
This chapter will present case studies illustrating the application of planned activity management in various project contexts, showcasing both successes and challenges. (Note: Specific case studies would need to be added here, detailing real-world examples of project planning and execution, highlighting the role of planned activities in achieving project goals and addressing setbacks.) Examples could include construction projects, software development projects, event planning, etc. Each case study should highlight the chosen techniques, models, and software used, and analyze the effectiveness of the approach taken.
