Activity Definition Guide: PMBOK 7th Edition

Activity Definition is a critical component of project time management which revolves around the identification and documentation of the specific actions to be performed to deliver project deliverables.

Importance: Without precise activity definition, project scheduling, estimating, controlling, and management could be drastically off track. It creates a clear roadmap for project execution and control, providing the groundwork for the sequence, resources, and durations in the project schedule.

Working: The process involves breaking down work packages into smaller, manageable activities that provide a basis for estimating, scheduling, executing, monitoring, and controlling the project work.

Exam Tips: Expect questions on the exam where you need to differentiate between the 'work package' and 'activity'. Remember, activities are measurable and controllable. In such questions, try to identify the lowest level of work in the scenario - this is typically the 'activity'.

Don't forget: 'Activity definition' is different from 'activity list'. The former is a process whereas the latter is a document resulting from that process. Being aware of this can help answer questions related to these concepts.

PMP - Activity Definition Example Questions

Test your knowledge of Activity Definition

Question 1

During activity definition for a construction project, a project manager identifies some concurrent activities. However, the manager has concerns over resource availability for these activities. What should the manager do?

Remove some resources from other activities without consultation. Plan for resource allocation considering the concurrent activities and adjust the project schedule where needed. Ignore the problem and hope for the best. Assign all resources to these concurrent activities regardless of availability.

Correct Answer: Plan for resource allocation considering the concurrent activities and adjust the project schedule where needed.

The best approach for managing resources in concurrent activities of a construction project is planning for resource allocation considering the concurrent activities and adjusting the project schedule where necessary. It's crucial to anticipate potential resource availability issues and make necessary adjustments to ensure smooth progress in project activities. Ignoring the problem and hoping for the best is not a proactive or efficient approach, as resource management issues can considerably slow down a project or even lead it to failure. By the same token, assigning all resources to concurrent activities irrespective of availability may overextend the resources and result in unnecessary stress, lower output quality and delays in other project parts. Lastly, removing resources from other activities without consultation can disrupt the workflow of those activities and create poor communication and misunderstanding within the team.

Question 2

In the domain of project management, Activity Definition involves identifying and documenting the specific actions to be performed to produce the project deliverables. Accurate activity definition is crucial for developing a reliable project schedule, estimating costs, and assessing risks. A Project Manager is tasked with Activity Definition for a new software development project aimed at creating a novel data analytics platform. After initial brainstorming and stakeholder consultations, the Project Manager organizes a series of workshops with the project team and subject matter experts to further delineate the activities necessary. Given the complex nature of the project, which includes integrating advanced machine learning algorithms and ensuring strict data privacy compliance, it becomes evident that an iterative approach to defining activities will be required. In addition to the iterative approach, the Project Manager decides to utilize a specific technique to ensure that all activities are correctly identified, adequately detailed, and aligned with the project objectives. Which of the following techniques would be MOST appropriate for the Project Manager to apply during the Activity Definition process in this scenario?

Bottom-up Estimating Parametric Estimating Decomposition Expert Judgment

Correct Answer: Decomposition

The most appropriate technique for the Project Manager to apply during the Activity Definition process in this scenario is Decomposition. Decomposition involves breaking down the project scope and project deliverables into smaller, more manageable components. This allows for a more detailed and accurate identification of the specific activities required to complete each component. Given the complex nature of the software development project, which includes advanced features and strict compliance requirements, decomposition will enable the Project Manager and team to progressively elaborate on the activities needed at a granular level. This iterative approach to activity definition aligns well with the progressive decomposition technique. Expert Judgment, while valuable, is more of an input to the process rather than a specific technique. Bottom-up Estimating and Parametric Estimating are techniques used for cost and duration estimation, not activity definition.

Question 3

You are a project manager at a software development company managing a large-scale project. The project is divided into different phases with various work packages. You have finished one phase and are about to start the next one, but you find difficulty in defining all the activities for the upcoming phase due to its complex nature. What should you do?

Delay the start of the next phase indefinitely until you figure it out. Start the phase without defining all activities. Use decomposition to break down the work packages into smaller, manageable activities. Ask a team member to define the activities as per their understanding.

Correct Answer: Use decomposition to break down the work packages into smaller, manageable activities.

Using decomposition to break down complex work packages into smaller, manageable activities is the best approach in this situation. When faced with a complex phase or work package, it's essential to divide it into smaller, well-defined tasks. This allows for better planning, resource allocation, and progress tracking. Starting the phase without fully defining the activities can lead to confusion, delays, and potential rework. Delaying the start of the next phase indefinitely is not a viable solution as it can jeopardize the entire project timeline. Asking a team member to define activities based on their understanding alone may result in incomplete or incorrect planning. As the project manager, it's your responsibility to ensure proper planning and execution of each phase, which is best achieved through decomposition and collaboration with the team.
