Your Challenge

  • There is a lack of understanding of the appropriate metrics to effectively manage capacity.
  • There is a lack of analytical tools to start managing and planning capacity.
  • Capacity management requires time and analytical skills.

Our Advice

Critical Insight

  • End users and stakeholders lack the ability to provide the correct information to identify current issues or future needs.
  • Organizational demands change so quickly that it’s difficult to forecast resource requirements accurately.
  • Start simple. Start with the monitoring data that is already gathered as part of normal routines.
  • Build intuitive metrics. When using Excel and simple monitoring data, stick with metrics such as percent utilization.
  • Know when to stop using Excel. If you need a Hadoop instance to handle the data, consider capacity management tools.

Impact and Result

  • Create a service-oriented capacity management and planning strategy that will meet changing business needs.
  • Adopt ITIL and COBIT frameworks to reduce the process and metric planning. Allow infrastructure managers to focus on developing the analytical skills and data gathering processes.
  • Align the capacity management with critical IT services; focus on those resources that enable key services.
