Practices-Outcomes-Metrics (POM)

Representative POMs are described for Data Reliability at each level of maturity.

1Initial
  • Practice
    Carry out some informal TCO tracking.
    Outcome
    Some familiarity with the application of TCO tools is emerging.
2Basic
  • Practice
    Set up a basic TCO assessment process to evaluate current practices and identify areas for improvement.
    Outcome
    There is confidence in the IT function that TCO projections are somewhat accurate.
    Metric
    % difference of TCO projections vs. actual.
  • Practice
    Conduct TCO assessment as part of the initial cost/benefit analysis for every IT service.
    Outcome
    TCO is established as a key requirement prior to new IT system investment.
    Metric
    % of protects that conduct a TCO assessment in the pre-investment stage.
3Intermediate
  • Practice
    Define the tolerances for TCO projections.
    Outcome
    Projected TCO is accurate within defined tolerances.
    Metric
    % difference of TCO projections vs. actual.
  • Practice
    Conduct TCO as part of initial project cost/benefit analysis and periodically as part of ongoing evaluation.
    Outcome
    Ongoing costs associated with IT are beginning to be assessed.
    Metric
    % of IT assets conducting pre and ongoing TCO assessments.
4Advanced
  • Practice
    Ensure TCO projections are within defined tolerances and are benchmarked against industry standards.
    Outcome
    There is a high degree of confidence that TCO projections are accurate and all IT stakeholders can plan according to these.
    Metric
    % of projects that exceed TCO forecast tolerances.
  • Practice
    Conduct TCO consistently throughout the initial and ongoing use phases.
    Outcome
    Ongoing costs associated with IT are consistently assessed.
    Metrics
    • % of IT assets conducting pre and ongoing TCO assessments.
    • # of ongoing TCO assessments conducted per IT asset.
5Optimized
  • Practice
    Continually review and optimize TCO reliability.
    Outcome
    There is full confidence in the reliability of the whole TCO process.
    Metric
    # of TCO reliability assessments per year.
  • Practice
    Make TCO projections a major category in all individual and group performance reviews.
    Outcome
    The reliability and accuracy of TCO projections is optimized, throughout the whole IT function.
    Metric
    # of TCO reliability assessments per year and their results.
  • Practice
    Conduct TCO consistently throughout every stage of the asset life cycle, including a post retirement assessment.
    Outcome
    TCO benefits are achieved at every stage in the asset life cycle.
    Metric
    % of IT assets conducting TCO assessments at pre, ongoing, and post investment stages.
