Final answer:
Securing written authorization for a project signifies the completion of the 'Develop project charter' phase, which outlines the project's scope, objectives, and stakeholders, and grants the project manager the authority to utilize resources.
Step-by-step explanation:
When you have secured written authorization for your project, the process that has been completed is Develop project charter. This initial phase involves defining the scope, objectives, and participants of a project, and it is critical for formally initiating the project within an organization. This step establishes a documented commitment to the project, often in the form of a project charter, which acts as a primary sales document for the project, essentially authorizing it to move forward.
The project charter is a key deliverable from the project initiation phase and it provides the project manager with the authority to apply organizational resources to project activities. Having the project's goals, roles, responsibilities, and high-level planning details articulated in a charter helps to set clear expectations and provides a roadmap for all stakeholders involved.
After a project charter is approved, subsequent phases such as Develop project management plan, Direct and manage project work, and others would follow. The written authorization marks a crucial milestone in the project's life cycle, signifying official approval to proceed with the project as planned.
