One of your portfolio team members is confused on the reason behind using the three processes: Define Portfolio, Optimize Portfolio, Authorize Portfolio and Manage Portfolio value. For him, we can…

Portfolio management processes are not optional; each serves a distinct governance purpose, and skipping one creates gaps in oversight, decision-making, and strategic alignment.

The processes are not similar - each has unique inputs, tools, techniques, and outputs defined separately in the standard because they address entirely different portfolio management activities.

Each portfolio management process addresses a fundamentally different governance function: Define Portfolio establishes scope and composition, Optimize Portfolio aligns and balances the component mix, Authorize Portfolio approves and resources components, and Manage Portfolio Value monitors benefit realization. These processes are interdependent - outputs from one feed inputs into others - and they run iteratively and continuously throughout the portfolio lifecycle rather than as a one-time linear sequence.

Stating that the processes should not be skipped because they are part of the standard is technically true but misses the key reason - it does not explain that they are interrelated and continuously executed, which is the substantive answer.
