You need to charter a project and ask for a budget.

We identify business processes and use a high-level assessment of business impact and implementation effort to prioritize the process for further discovery activities.

Different estimating techniques presented in this section gradually improve in both accuracy and precision, thus reducing the cone of uncertainty as more process information is collected and understood during the project.

Use a budgetary estimate when you need a higher level of confidence (reduced uncertainty) for project planning.

We start managing project implementation with a detailed estimate, we use user stories and story points to size delivery components.

Section provides ranges for the level of effort required given characteristic levels of complexity.
