A wiki knowledge base is a collaborative online platform that allows users to create, edit, and share information about a specific topic or domain1. A wiki knowledge base is best to use for storing lessons learned because it enables easy access, retrieval, and update of the lessons learned by project teams and stakeholders2. A wiki knowledge base can also support keyword search, version control, and linking of related documents3. A wiki knowledge base is different from a whiteboard, which is a physical or digital board that can be used for brainstorming, sketching, or presenting ideas; a content management system, which is a software application that allows users to create, manage, and publish digital content; and a workflow platform, which is a software tool that automates and streamlines business processes4.

A quality assurance plan is a plan that defines and documents the standards, criteria, methods, activities, and tools for ensuring and verifying that the quality requirements and expectations of a project are met. A quality assurance plan can help to improve the quality of the project processes and deliverables and prevent or reduce defects or errors.

A statement of work (SOW) is a formal document that defines the entire scope of work involved for a vendor and clarifies deliverables, costs, and timeline1. It serves as a contractual agreement between a vendor and a client, providing a comprehensive description of the work to be performed2. A reason to use a SOW on a project is to ensure the team stays within the scope of the contract, as it outlines what the team will and won't do on a project, saving from painful client negotiations and protecting the timeline and the bottom line3.

Submit a change request to the change control board. The project manager should submit a change request to the change control board (CCB) if they realize that the project will not be completed on time due to resource constraints. A change request is a formal proposal to modify any aspect of the project, such as scope, schedule, cost, quality, or resources. A change request must be submitted to the CCB, which is a group of stakeholders who are authorized to review and approve changes. Submitting a change request can help to document the impact of the resource constraints on the project and seek approval for any corrective actions or preventive actions12
