Your Challenge

  • Application Development Managers have to defend maintenance budgets to executives.
  • Often the estimates are based on a single method – expert estimation – instead of also including parametric estimation in the process.
  • The result is a variance in estimated and actual budgets caused by varying degrees of scope interpretation by experts who are called upon to estimate.

Our Advice

Critical Insight

  • Having a single expert estimation technique is not enough. You need to include an analytical parametric technique to quickly surface assumptions and have that discussion early rather than having to defend a budget shortfall.

Impact and Result

  • Produce a charter that will help you sell an optimized application maintenance estimation process internally for the benefit of the business.

Research & Tools

1. Understand the project rationale

Assess organizational preparedness for AME process optimization.

2. Structure the AME optimization team

Set up a project team for optimizing the AME process and obtain approval to proceed.

3. Analyze the current AME process gaps

Identify the gaps that might prevent a successful implementation.

4. Optimize the AME process

Document the new optimized process and identify implementation costs.

5. Implement the AME process

Develop the rollout and communications plan, and prepare for hurdles.

6. Measure ongoing value

Track metrics and apply lessons learned to other projects.

Guided Implementations

This guided implementation is a four call advisory process.

Call #1 - Evaluate the team structure

You come with your draft project team structure, and we will help you review the structure and discuss governance so that you will have a refined project team structure in place.

Call #2 - Analyze the current AME process gaps

You come with your complete gap analysis, and we will help you identify additional alignment or process gaps for consideration so that you will have a complete gap assessment prior to optimization.

Call #3 - Optimize the AME process and get charter sign-off

You come with your optimized AME process, cost, traceability matrix, and project charter, and we will help you validate the business alignment and provide feedback on your charter so that you will have improved alignment with business needs and an improved charter.

Call #4 - Implement the optimized AME process

You come with your rollout plan and communications brief, and we will help you critically analyze for additional gaps you may wish to consider so that you will be better prepared for the rollout and any possible changes.

Onsite Workshop

Book Your Workshop

Onsite workshops offer an easy way to accelerate your project. If you are unable to do the project yourself, and a Guided Implementation isn't enough, we offer low-cost onsite delivery of our project workshops. We take you through every phase of your project and ensure that you have a roadmap in place to complete your project successfully.
