The roadmap is based on the results of the business requirements document, interviews and scenario-based planning completed in Stage One. The roadmap includes a system architecture that lays out a long-term structure and identifies key system components, standards and building blocks while specifying their relationship to one another. Identify evaluation and vendor selection criteria. The evaluation criteria and priorities will reflect the business objectives defined in Stage One. Create an RFI or RFP that provides corporate background and rationale, goals for the project, a description of your current and target computing environment, and evaluation criteria.
Suppliers can be a rich source of information and assistance.
Let them help you define the architecture and technology solutions. Evaluate responses to the RFP based on the criteria and priorities defined in Stage One. Conduct a detailed cost and value analysis based on empirical, not just theoretical, analysis. Use industry standard baselines for analyzing requirements for calculating value and for staffing, service level agreements, architecture and management tradeoffs. Test alternative solutions.
