Why Transformation Projects FailWhy Transformation Projects Fail
Flawed or incomplete transformation strategy Relying on technical expertise alone Inadequately trained people tied to old technologies “We know our application inside-out!” Little time spent gathering or validating requirements Architecture is not the primary consideration No recognition of a distinctive transformation process Inadequate planning and weak resolve to follow plans Lack of long-term commitment from management Management predetermines technical decisions
Adapted from Bergey, Smith, Tilley, Weiderman, and Woods, Why Reengineering Projects Fail (CMU/SEI-99-TR-010). Carnegie-Mellon Software Engineering Institute

Guidelines for Transformation SuccessGuidelines for Transformation Success
Formulate a complete and coherent strategy Technical expertise and disciplined management Invest in training people on new technology Invest in learning what you don’t know Gather and validate requirements with customers Architecture is the foundation Establish an appropriate transformation process Invest in planning and discipline to execute plans Commit to transformation as a long-term investment Technical decisions based on proper analysis

Zachman FrameworkZachman Framework
Application Transformation projects carry a significant level of risk…
…which must be managed and mitigated by gathering complete and accurate information through a methodical process of discovery and
analysis
The Zachman Framework helps to identify and analyze areas that are relevant to a given application transformation scenario
Simply a mental model

Next Steps Next Steps
Start NOW– Business plan– Application roadmap, using the Reference Architecture– Get to the current environment (Progress Version 9)– Training– Plan, Plan, Plan
Get comfortable with the OpenEdge Reference Architecture– Read presentation – Attend Seminars / Classes
Training– Skills Assessment – create education plan– Non-Progress training may be needed– Commit to training your people– Willing to ‘invest in themselves’
Understand it’s not a short process, must stay committed
