This handbook provides a uniform approach for performing LLA as a living risk assessment
document for GSFC missions that is performed concurrently with design efforts and refined as
the designs, materials, mission parameters, or processes are refined.

LLA can provide the following project benefits:
- Verification of NASA limited-life requirement and Goddard Open Learning Design (GOLD)
Rule compliance
- Identification of candidates for Critical Items List
- Risk identification
- Identification of items requiring maintenance or refurbishment
- Input to sparing plans
- Input to test plans

Proper LLA greatly reduces the risk of premature mission failures by ensuring life margin for
wear-out or age-limited items. It also enables missions to be extended with some confidence that
hardware will not fail due to life-limiting characteristics.
