Tom is using a Template. As your company completes projects, the documents created along the way are stored in an Organizational Process Asset library. The WBS's from those past projects can be a great way to be sure that you are thinking of all of the work that you will need to do from the very beginning. Your project will never match the old WBS exactly, but there could be work packages listed there that you might not have thought of on your own but really are necessary in your project.

Creating internal projects to provide internships for the students is a change in the project scope that requires approval from the customer and other stakeholders. Therefore, the project manager should create a change request with the scope of the new internal projects and submit it to the Perform Integrated Change Control process1. The change request should include the rationale, benefits, risks, and impacts of the proposed change on the project objectives, deliverables, schedule, cost, quality, and resources. The project manager should also update the project management plan and other relevant documents to reflect the change in scope.
To plan and execute the new internal projects, the project manager should create a work breakdown structure (WBS) of the new scope with the internal projects2. A WBS is a hierarchical decomposition of the project scope into manageable deliverables and work packages. A WBS helps the project manager to define, organize, and monitor the project work, as well as to allocate resources, assign responsibilities, and estimate costs and durations. The project manager should involve the project team and the interns in creating the WBS to ensure their buy-in and commitment.
To ensure that the internal projects meet the customer's expectations and the project's quality standards, the project manager should manage the quality of the delivery3. Quality management involves planning, implementing, and controlling quality activities to ensure that the project deliverables conform to the requirements and specifications. The project manager should use quality tools and techniques, such as quality checklists, audits, inspections, testing, and reviews, to measure and improve the quality of the internal projects.
The project manager should also document and communicate the quality results and feedback to the project team, the interns, the customer, and other stakeholders.
