3 Process Posture Map-流程态势图

3.1 elements of your current state that need to be supported or revised
3.2 practical map of how everything in your enterprise architecture will work together
3.3 five tags to each process
- Start: We do not do this in a meaningful or established way as an organization, but should define how we want to do this and begin to implement that.
- Continue: This capability may require the normal continuous improvements of the local leaders but is generally is on track.
- Invest: We have a nascent(新兴) activity here that may have strong roots or certain strong practices and potential, and we would realize gains if we focused and grew the capability.
- Assess（评估）: We have an ostensible（表面） capability here, but it should be examined for efficiency improvements in some areas.
- Revise: This is clearly an ailing or weak capability that must be overhauled(彻底检修）.

  8.3 A purposeful APM exercise will help you answer the following questions
• Does your application portfolio properly support the current and stated future aims of the business?
• Are you devoting enough resources to your strategic applications?
• Are you providing too much financial support to noncritical applications?
• Are you wasting money on legacy applications of low business value?
• How can you plan future application consolidation or rationalization?
• Can you reduce overall IT cost by changing the way you support certain applications?
• What risks do you have in the portfolio? Where should you focus thought and design effort?

8.4 use Management map to help you

• Identify and eliminate redundant and unused applications.
• Consolidate similar applications into a single new application.
• Retire older and more expensive-to-maintain applications.
• Determine which data flows through which applications to optimize security controls.

8.5 steps

• 1. List the known business goals.
• 2. List your technological goals
• 3. List your applications altogether, and the owners in business and tech.
• 4. Apply the APM rubric(评分标准) to the application list to cluster them according to business and technology attributes.
  • 1. As you start the work, be sure that you first agree on your business goals and the list of applications
  • 2. make sure that you have the list of the proper owners for each system. You’ll need to consult with these people later when it’s time to negotiate the plans for their applications.
  • 3.establish a set of questions
    • The questions are divided into business and technology
    • They aren’t open-ended, but rather should have a numeric score attached to them, such as 1–5.
      
      
• 5. Evaluate and list strategies for each application-各种维度输出

8.8.2 steps

• First, list the projects.
• Next, determine their net value to the business based on standard metrics such as internal rate of return (IRR) or anticipated return on investment (ROI)
• Then, examine the quality of the project based on metrics such as the technology employed, the capabilities it provides, and whether the costs are in line and the timeline is on track
• Finally, you can plot them in a heat map.
