Now that you've met with the stakeholders and received the information you requested, it's time to create the project scope and have them sign off on the project. If you've planned your input carefully, the project scope should be easy to write with clear and identifiable goals, budgets, resources, scheduling, and deliverables.
Your scope statement should only include items that meet the project's needs to avoid scope creep. On the other hand, it shouldn't be void of essentials provided to you by the stakeholders. Consider the scope statement as an agreement between you, the project manager, your resources, and the stakeholders. Explain the necessity of their acknowledgment of the scope statement before work begins. Be sure the stakeholders understand that you will be able to identify changes to the scope statement early on and submit for their approval.
A well written scope statement can guide you and your team to a successful outcome. Having stakeholders help you write the scope statement almost always guarantees their happiness and your high achievement which will bring recognition and future projects. Keep the stakeholders informed during the project. However, let them know upfront that once the scope statement is defined, their input will be minimal until progress meetings.
Nothing can harm a project faster than interference from stakeholders who want an outcome but constantly change the scope of the project. Be forefront in your expertise and deliver them the scope statement they want, which you wrote from their direction.
