and Systems Integration

The Integrated Modeling Method can be applied in many ways to help a company with analysis, redesign and improvement of its enterprise structure. Listed below are some of the ways it can help, and some of the results it can produce.

Quantitative Analysis

Integrated Modeling can help with cost-benefit and risk quantification. Although it does not perform the actual quantification, the integrated model provides an accurate structural basis that facilitates quantification and impact analyses. Integrated Modeling can:
  • Clarify the scope and boundaries of a process-improvement project or other business initiative, based on the inherent structure of the business.
  • For a given initiative, show where and how the business structure will change, and pinpoint cost and benefit locations and magnitude.
  • Reduce risk, surprises and unintended consequences, by bringing to light where and how a change to one part of the business will impact other parts -- before the initiative is undertaken.

Process Reengineering

Integrated Modeling can help with process reengineering projects, which often operate in isolation from each other. Use of the integrated model architectural frameworks becomes increasingly important when there are multiple reengineering projects in different parts of the business, or when an end-to-end enterprise-level core process is involved. Integrated Modeling can:
  • Clarify the scope and boundaries of each project, to avoid overlaps and voids.
  • Align each project with the inherent process structure of the business.
  • Show how a change to a process in one part of the business will impact other processes in other parts of the business.
  • Make it easy to identify process interdependencies and data-sharing requirements.
  • Make it easy to relate process changes to the lifecycles of key business data objects.

Systems Integration

Integrated Modeling can help with systems integration across multiple initiatives, application development teams, or contractors. Use of the integrated model makes it easy to rationalize and align the multiple efforts against the basic architectural structure of the business. Integrated Modeling can:
  • Provide an enterprise roadmap that clearly shows who is responsible for which area of the business.
  • Make it easy to resolve conflicts or uncertainties over project boundaries.
  • Help define interface requirements and interdependencies among the multiple projects.
  • Clarify priorities and development sequence requirements.
