Define clear objectives and keep them POSITIVE ? Driven by key business issues ? Ensure that the process is rolled out effectively – target a subset, test, validate and improve ? Begin with manual methods then, consider automation (DataDrill) ? Train, Train, Train ? Provide time for the processes to mature。 variability tends to be very high initially – expect noise and change ? Assist the project teams in understanding, analyzing and improving the processes through metric reporting ? Communicate, Communicate, Communicate 24 ? Obtain Executive Sponsor ? Define the business and IT objectives for the measurement and improvement program (must be data driven) ? Conduct JAD session to identify possible measures ? Select measures that align with program objectives and improve IT performance ? Identify the information requirement, author, data source and tools ? Identify the core set or phased implementation plan for measures and validate with author, contributor and user that they align with project, department and anizational goals Implementing A Metrics Program 25 ? Develop the metric collection and reporting solution including automation, collection, graphing and reporting processes ? Test, fine tune, verify and pilot all reports and measures ? Package multiple measures into a metrics release ? Identify and train a core team of authors, contributors and users in the interpretation and use of all measures to improve business results ? Production rollout begins ? Monitor, improve, retire and implement new measures as the anization matures in process and measurement capabilities ? Capture, municate and inform all of Program results ? Integrate into a Business performance Program Implementing A Metrics Program 26 ? Alignment with the IT Governance and/or PMO Program ? Alignment with certification objectives (CMM/CMMI/Iso, etc)
