Overview of CSF Analysis
CSF analysis is:
A method developed at MIT's Sloan school by John Rockart to guide businesses in creating and measuring success Widely used for technology and architectural planning in enterprise I/T A top-down methodology that is especially suitable for designing systems as opposed to applications A reductionist method for going from an abstract vision to concrete requirements What Is a Critical Success Factor?
A key area where satisfactory performance is required for the organization to achieve its goals A means of identifying the tasks and requirements needed for success At the lowest level, CSFs become concrete requirements
A means to prioritize requirements

Start with a vision: mission statement
Develop 5-6 high level goals
Develop hierarchy of goals and their success factors
Leads to concrete requirements at the lowest level of decomposition (a single, implementable idea) Along the way, identify the problems being solved and the assumptions being made Cross-reference usage scenarios and problems with requirements Results of the Analysis
Hierarchy of goals and CSFs
Lists of requirements, problems, and assumptions
Problems vs. Requirements matrix
Usage scenarios vs. Requirements matrix
Solid usage scenarios
Relationship to Usage Scenarios
Usage scenarios or "use cases"; provide a means of determining: Are the requirements aligned and self-consistent?
Are the needs of the user being met as well as those of the enterprise? Are the requirements complete?
Example: From Goal to Requirements
