	The Growth Potential Design Margin ( <math>GPDM</math> ) can be considered as a safety margin when setting target MTBF values for the reliability growth plan. It is common for systems to degrade in terms of reliability when a prototype product is going into full manufacturing due to variation in material, processes, etc. Furthermore, the in-house reliability growth testing usually overestimates the actual product reliability, since the field usage conditions may not be perfectly simulated during growth testing. Typical values for the <math>GPDM</math> are around 1.2. Higher values yield less risk for the program, but require a more rigorous reliability growth test plan. Lower values imply higher program risk, with less safety margin.


	During the planning stage, the growth potential MTBF, <math>{{M}_{GP}},</math> can be calculated based on the goal MTBF, <math>{{M}_{G}},</math> and the growth potential design margin, <math>GPDM</math> :


	~~::<math>{{M}_{GP}}=GPDM\cdot {{M}_{G}}</math>~~
