Solution Abstract

What? Why?

What is Portfolio Rationalization?
It is the act of streamlining an organization's existing portfolio to improve efficiency, reduce complexity, and lower TCO. The portfolio spans people-process-technology, and consists of hardware, software, data, and process.

Key points worth noting. It's about -

streamlining the existing portfolio;
improving efficiency;
reducing complexity;
lowering TCO of the portfolio;
people, process, technology; and
all assets - hardware, software, data, process.

Most often a portfolio rationalization process is composed of :-

rationalization of applications;
rationalization of IT;
rationalization of processes;
rationalization of data;
rationalization of infrastructure.

Why is Portfolio Rationalization needed? What are the benefits?
The key goal is to :-

reduce operations cost;
reduce maintenance cost;
reduce innovation cost; and
increase savings.

An effective rationalization process can help -

finding capital which can be re-invested;
optimize IT budget in operations and maintenance areas; and
enable organization remove its Tech-Debts and become future ready.

The Essential Method

The 10000 Feet View

The Stages

At an abstract level portfolio rationalization consists of multiple stages, i.e., :-

assessment, i.e., assessing organization's as-is portfolio and building the asset repository;
evaluation, i.e., ; evaluating the portfolio's current state, and defining the target state;
planning the rationalization;
executing the rationalization; and
establishing governance and continuity.

The Building Blocks

The below mind-map depicts the essential building-blocks and aspects involved in a portfolio rationalization process.

The Process Model

Portfolio Rationalization is a perpetual journey, and not an one-off project.

A successful rationalization needs a process model, which can achieve the immediate rationalization goals, and establish continuity. A well defined model consists of multiple elements, including :-

the mechanism to detect the business need for a rationalization;
the scope which is well defined and achievable;
the phase to assess the portfolio and build the as-is asset inventory;
the phase to evaluate portfolio's health;
the target-state definition;
the rationalization plan consisting of budget, people, timelines;
the phase to transform the portfolio to target-state; and
a well defined governance process which can track the transformation, and provide continuity.

The sketch depicts the high-level process model.
