5 2. Translate Requirements into Design Objective #1: Failure Identification / Prediction Supportability as a JCIDS Design Objective The ability of the system to identify and/or predict failures down to a certain subsystem within a given percentage of accuracy. Potential attributes include health management, prognostics and diagnostics capabilities, Condition-Based Maintenance Plus (CBM+) enablers, support equipment and parts commonality. Attributes Which May be Considered KPPs or KSAs Include: Built-In-Test (BIT) Fault Detection - a measure of recorded BIT indications which lead to confirmed hardware failures. BIT Fault Isolation - A measure of recorded BIT indications which correctly identify the faulty replacement unit, either directly or through prescribed maintenance procedures. BIT False Alarms - A measure of recorded BIT indications showing a failure when none has occurred 5

6 2. Translate Requirements into Design Objective #2: Rapid Restoration of Service Maintainability as a JCIDS Design Objective The ability of the system to be brought back to a state of normal function or utility. Attributes Which May be Considered KPPs or KSAs Include: Corrective Maintenance - All actions performed as a result of any failure, to restore a system, subsystem, or component to a required condition. Normally expressed as Mean Down Time (MDT), Mean Time To Repair (MTTR) or a calculation of ease of maintainability. Mission Maintainability - The ability of the system to be retained in or restored to a specified mission condition. Maintenance Burden - A measure of maintainability related to the system's demand for maintenance manpower Maintainability Design Attributes Accessibility Physical placement of hardware to facilitate maintenance. Modularity Grouping of similar functions within a physical area. Testability Extent to which the operational status of modules can be tested 6

7 2. Translate Requirements into Design Objective #3: Affordable Cost / Effective Sustainment JCIDS Design Objective Cost Sustained Operations Transportability & Deployability Logistics Footprint Definition / Attributes Included as one of the O&S Cost KSA, normally expressed as the total O&S costs regardless of the funding source over the projected life cycle of the capability solution in base year dollars The ability of the system to be employed in an operational context for a given timeframe without logistics resupply or support The ability of the system to be moved and deployed within the Department's transportation infrastructure Materiel, mobility, and space required to effectively sustain the system in the field 7

8 3. Mature the Design Through Testing Designing for R&M / Developmental Test Design for Reliability (DFR) is a System Engineering process that identifies and eliminates failure modes, and ensures the reliability and supportability of designs: Redundancy Derating Thermal Design Integrity Analysis Software RAM Parts Selection Program Critical Items Analysis Storage Analysis Sneak Circuit Analysis Developmental Test & Evaluation (DT&E) Laboratory Limited Operational Simulation Environmental Testing (MIL-STD-810C) Altitude Hi / Low Temp / Shock Vibration Heat/Cold Solar Radiance Rain (Wind and Ice) Humidity / Fungus Wind/Fog Salt The Failure Reporting And Correction System (FRACAS) Is An Integral Part Of The Development Process 8

Continuously Evaluate Suitability Independent Logistics Assessment (ILA) The 2009 DoD Weapon Systems Acquisition Reform Product Support Assessment (WSAR-PSA) included the recommendation to implement independent Logistics Assessments during Weapon System Development, Production and Post-initial Operational Capability (Post IOC) (1) Assessment Criteria (2) ILA Rating Criteria (3) Risk Rating Summary ILA Provides Critical Technical And Management Information To Support the Governance Process 16

17 6. Continuously Evaluate Suitability Initial Operational Test & Evaluation (IOT&E) Suitability is the degree to which a system can be satisfactorily placed in field use, with consideration given to reliability, availability, compatibility, transportability, interoperability, wartime usage rates, maintainability, safety, human factors, manpower supportability, logistics supportability, documentation, environmental effects, and training requirements. The Log Demo evaluates the Suitability of system support that ensures the right resources, with the appropriate skill level, under the appropriate environment conditions, to achieve the maintenance task in the time allotted. $ A o MTTR Logistics Footprint Maintenance Concept 17
