We are often called upon to analyze applications for suitability of porting to Cloud Foundry. We quickly draw up the following chart and prepare a forrester style 4 quadrant graph of Technical suitability vs Business Criticality. I am embedding the technical criteria for evaluating an app below :
The quadrants on the SWOT analysis graph below are the axis of whatever is important to you to prioritize the apps - typically the axes are - Technical complexity and effort vs Strategic business importance. It is a way of categorizing your apps based on your goals and interests that come out during the inception.
Typically the X axis is (technical complexity - how much do you know about the app) - Y axis is (Business criticality - How important is this to the business) - other factors come into play as well
