Why do organizations need to tailor project management concepts, such as those found in the PMBOK® Guide, to create their own methodologies?

Explanation:

Although each project is different and unique, according to the Method Statement of PMBoK, customising is required. Not that every procedure, tool, methodology, input, or output listed in the PMBoK Guide is mandated for every project. Scope, timeline, cost, materials, quality, and danger should all be considered while tailoring.
