**The Monitoring Maintenance Lifecycle** (MML) is a monitoring development process to lower maintenance expenses and improve the dependability of IT infrastructure with regard to service recovery-related issues. It is based on the classical [Waterfall model](/source/Waterfall_model).

Monitoring Maintenance Lifecycle are methods and standards for improving and mastering maintenance [processes](/source/Industrial_process), supporting processes and management processes throughout the monitoring lifecycle.

The quest for the optimized mix of processes has resulted in different [standards](/source/International_standard) throughout the history. One of the latest which was published is the [ISO/IEC 12207](/source/ISO%2FIEC_12207) [standard](/source/International_standard). This standard was proposed in 1988 and published in August 1995. It was created to establish a common international [framework](/source/Conceptual_framework) to acquire, supply, develop, operate, and maintain.

[ISO/IEC 12207](/source/ISO%2FIEC_12207) consists of three types of processes:[1]

- Primary lifecycle processes;

- Supporting lifecycle processes;

- Organizational lifecycle processes.

## Supply

During the supply phase a [project management plan](/source/Project_plan) is developed based on [RUP](/source/IBM_Rational_Unified_Process). This plan contains information about the project such as different milestones that need to be reached. This [project management plan](/source/Project_plan) is needed in the start up phase and throughout the monitoring and maintenance lifecycle.
