This paper presents a detailed Reliability Growth (RG) planning approach that may be utilized for developing RG programs for discrete-use systems, thereby facilitating the implementation of the aforementioned DoD reliability policies. More specifically, this approach, hereafter referred to as PM2-Discrete, may be utilized for developing RG programs and associated planning curves that: (1) portray planned reliability achievement as a function of program resources; (2) serve as a baseline against which demonstrated reliability values may be compared throughout a test program (for tracking purposes); and (3) illustrate and quantify the feasibility of a test program in achieving interim and final reliability goals. In particular, PM2-Discrete possesses a series of management metrics that may be used to assess the effectiveness of proposed RG programs. These metrics serve as concomitant measures of programmatic risk and system maturity that may also be assessed during testing for progress reporting purposes. A methodology overview and application of PM2-Discrete is given, as well as an abbreviated overview of relevant literature within the area of RG planning. Note that derivations of the model equations (not presented herein), are available and may be referenced in...
