Project Management & Scheduling Flashcards

What is the main goal of project scheduling?

Answer: To organize tasks and timelines for timely completion

Project scheduling is the process of listing activities, determining their dependencies, estimating durations, and assigning resources to create a timeline for project execution. Its main goal is to ensure that all project tasks are completed in a logical sequence and within the specified timeframe, leading to successful and timely project delivery.

Which tool is commonly used for visualizing project schedules?

Answer: Gantt charts

Gantt charts are widely used project management tools that visually represent a project schedule, showing tasks, their durations, and dependencies against a timeline. They provide a clear, easy-to-understand overview of the project's progress, helping teams and stakeholders track milestones and deadlines effectively.

What does the critical path method (CPM) identify?

Answer: The sequence of tasks that controls project completion time

The Critical Path Method (CPM) is a project scheduling technique used to identify the longest sequence of dependent activities that must be completed on time for the entire project to finish on schedule. Any delay in a critical path task will directly delay the project's overall completion, making it crucial for project managers to monitor these tasks closely.

Why is resource leveling important in scheduling?

Answer: To prevent resource conflicts and balance workloads

Resource leveling is a scheduling technique used to adjust the project schedule to optimize the allocation of resources, especially when resources are over-allocated or limited. It helps to smooth out peaks and valleys in resource demand, preventing burnout, improving efficiency, and ensuring that tasks can be completed with available resources.

What is a milestone in project scheduling?

Answer: A significant event or checkpoint

A milestone in project scheduling represents a significant point or event in the project lifecycle, often marking the completion of a major deliverable or phase. Milestones have zero duration but are crucial for tracking progress, communicating achievements, and ensuring the project stays on track towards its objectives.

Which scheduling method uses optimistic, pessimistic, and most likely time estimates?

Answer: Program Evaluation and Review Technique (PERT)

Program Evaluation and Review Technique (PERT) is a project management tool used to analyze and represent the tasks involved in completing a project, particularly useful when activity durations are uncertain. It employs a three-point estimation technique (optimistic, pessimistic, and most likely) to calculate a weighted average duration for each task, providing a more realistic and probabilistic view of project completion times.

What does float or slack time represent in scheduling?

Answer: Time a task can be delayed without impacting project deadline

Float, also known as slack time, refers to the amount of time a task can be delayed without affecting the start date of subsequent tasks or the overall project completion date. Identifying float allows project managers flexibility in scheduling and resource allocation, helping to manage unexpected delays without jeopardizing the project timeline.

Why is updating the schedule regularly important?

Answer: To track progress and manage adjustments

Regular schedule updates are essential for monitoring the actual progress against the planned timeline, identifying deviations, and making necessary adjustments. This proactive approach allows project managers to address issues promptly, reallocate resources, and communicate accurate status to stakeholders, ensuring the project remains on track.

What is a key challenge in project scheduling?

Answer: Estimating durations and dependencies accurately

A key challenge in project scheduling is accurately estimating the time required for each task and correctly identifying the logical relationships (dependencies) between them. Inaccurate estimates or overlooked dependencies can lead to unrealistic schedules, resource conflicts, and ultimately, project delays and cost overruns.
