In the age of the digital economy, when business agility and quick delivery are required to compete effectively, having a rigid and costly application portfolio can become truly detrimental to the business.
Capture a Baseline
Discover and capture a baseline state of capabilities.
The best place to start is to look at application capabilities relative to the company vision. Record the core applications, platforms, products, processes, risk profiles and costs to capture the "as is" or "baseline" state of existing capabilities relative to future focus areas for all of the different lines of business. Also consider geographies, product lines, and other key factors specific to the organization. Keep in mind that there are different levels of granularity that some companies need to drill down to, depending on the markets for their products/services.
