Capacity Governance
Capacity Governance involves establishing policies, processes, and controls to ensure effective capacity management. It ensures that capacity management practices are aligned with organizational goals.
Example: An IT department establishes a governance framework that includes regular reviews of capacity management practices and compliance with standards.
Capacity Metrics
Capacity Metrics are key performance indicators (KPIs) used to measure and monitor capacity management effectiveness. They provide insights into resource usage and performance.
Example: An IT team tracks metrics such as CPU utilization, memory usage, and network throughput to assess the performance and capacity of IT resources.
Capacity Escalation
Capacity Escalation involves escalating capacity issues to higher management when they cannot be resolved at the operational level. It ensures that critical capacity issues are addressed promptly.
Example: An IT department escalates a capacity issue with a critical application to senior management when initial attempts to resolve the issue are unsuccessful.
Capacity Review
Capacity Review involves periodically assessing the effectiveness of capacity management practices. It ensures that capacity management strategies are up-to-date and aligned with business needs.
Example: An IT team conducts quarterly capacity reviews to assess the performance of capacity management practices and identify areas for improvement.
Capacity Strategy
Capacity Strategy outlines the approach and plans for managing IT capacity to meet business needs. It ensures that capacity management is aligned with business goals and objectives.
Example: An IT department develops a capacity strategy that includes plans for scaling resources to support business growth and improving resource utilization.
Capacity Tools
Capacity Tools are software applications and platforms used to support capacity management activities. They help in monitoring, planning, and optimizing IT resources.
Example: An IT team uses capacity management tools to monitor resource usage, generate capacity reports, and simulate capacity scenarios.
Capacity Policies
Capacity Policies are guidelines and rules established to govern capacity management practices. They ensure consistency and compliance with organizational standards.
Example: An IT department establishes policies that define the thresholds for resource usage and the procedures for addressing capacity issues.
Capacity Standards
Capacity Standards are predefined criteria and benchmarks for measuring and managing IT capacity. They ensure that capacity management practices meet industry best practices.
Example: An IT team adopts industry standards for server utilization and response times to ensure that capacity management practices are aligned with best practices.
