KPI

Key performance indicator; measures that determine how well the process is performing in enabling the goal to be reached. They are lead indicators of whether a goal will likely be reached, and are good indicators of capabilities, practices and skills. They measure the activity goals, which are the actions the process owner must take to achieve effective process performance.

 

Maturity

In business, indicates the degree of reliability or dependency the business can place on a process achieving the desired goals or objectives.

 

Measure

A standard used to evaluate and communicate performance against expected results. Measures are normally quantitative in nature capturing numbers, dollars, percentages, etc., but can also address qualitative information such as customer satisfaction. Reporting and monitoring measures help an organization gauge progress toward effective implementation of strategy.

These can be measured only after the fact and, therefore, are called ‘lag indicators’.

 

Performance

In IT, the actual implementation or achievement of a process.

 

Performance drivers

Measures that are considered the ‘drivers’ of lag indicators. They can be measured before the outcome is clear and, therefore, are called ‘lead indicators’. There is an assumed relationship between the two that suggests that improved performance in a leading indicator will drive better performance in the lagging indicator. They are also referred to as key performance indicators (KPIs) and are used to indicate whether goals are likely to be met.

Portfolio

A grouping of programs, projects, services or assets selected, managed and monitored to optimize business return.

 

Preventive control

Processes have clear business reasons for existing, accountable owners, clear roles and responsibilities around the execution of the process, and the means to measure performance.

 

Program

A structured grouping of interdependent projects that includes the full scope of business, process, people, technology and organizational activities that are required (both necessary and sufficient) to achieve a clearly specified business outcome.

 

Project

A structured set of activities concerned with delivering to the enterprise a defined capability (that is necessary but not sufficient to achieve a required business outcome) based on an agreed-upon schedule and budget.

Typical phases include the feasibility study, requirements study, requirements definition, detailed design, programming, testing, installation and post-implementation review, but not the service delivery or benefits realization activities.

 

Segregation/separation of duties
