Application portfolio management is an approach to help return control to application managers. In this series of posts, I'll take a look at best practices for managing the application portfolio.
- Goal: Constant fire-fighting is no way to run a development organization. Especially in today's era of tight budgets and fast change. In this post I'll summarize the goal of APM and set the stage for a discussion of best practices. Read the post.
- Questions and Metrics: APM data should answer questions that address a specific goal. Say, ‘why is this business process inflexible?’, ‘where can I cut costs?’, or ‘where is my software architecture flawed?’. To answer these different questions requires different combinations and weightings of data (user surveys, application code, or external sources). Sometimes more of one source, sometimes another.

- Decision-Makers: APM data needs vary based on where you are in the organization. Higher level managers require higher level abstractions, particularly of technical metrics. Also, different types of users will have different data needs. An architect may want technical complexity data, but it may only be meaningful to him if it is filtered by architectural models.

- Maturity: There are different levels of maturity for decision-making. This maturity directly affects which metrics are accessible in the first place and also indirectly because it determines the kind of business goals that an organization is prepared to address. Read the post.
- What’s next: As a particular initiative moves from “decision” to “action”, different data may be needed. More “bottom-up” data may be necessary to implement the decisions at this stage. Further, different metrics can be monitored to ensure the success of a given development or modernization project as it is executed. Read the post.
