A wiki knowledge base is a tool that allows the project team to store, organize, and share information that is captured throughout the life cycle of a project. A wiki knowledge base is stored in a centralized location that is easily accessible to all stakeholders via a web browser. A wiki knowledge base also provides search functionality that enables the users to find the information they need quickly and easily. A wiki knowledge base can help the project team to document the project requirements, scope, schedule, budget, quality, risks, issues, lessons learned, and best practices.

A wiki knowledge base is different from a secure folder, which is a tool that protects the files and folders from unauthorized access or modification. A secure folder may not be easily accessible to all stakeholders, and may not provide search functionality or collaboration features. A wiki knowledge base is also different from a real-time, multiauthoring editing software, which is a tool that allows the project team to create and edit documents simultaneously and synchronously. A real-time, multiauthoring editing software may not be suitable for storing large amounts of information, and may not provide the same level of organization and structure as a wiki knowledge base. A wiki knowledge base is also different from a digital whiteboard, which is a tool that allows the project team to brainstorm, visualize, and communicate ideas. A digital whiteboard is not designed for storing information, and may not provide the same level of search functionality or security as a wiki knowledge base.
