1 Redefining Supportability Supportability That characteristic of a system and its support system design that provides for sustained system performance at a required readiness level when supported in accordance with specified concepts and procedures. Supportability That characteristic of a system and its support system design that provides for sustained system performance at a required readiness level when supported in accordance with specified concepts and procedures. Supportability: Supportability as defined herein (a shift in the paradigm) is a metric that addresses every support event within the domain of the Integrated Logistics Support Elements, with respect to support event frequency, event duration, and event cost. This is reflected in a composite, quantitative and qualitative characteristic of the supported system (project) to meet specified operational requirements for its intended life cycle, and is optimized for Total Ownership (TOC).

2 Supportability Approach must Emphasize Support Event Characterization Beyond Traditional Operational Availability (A O ) TRADITIONAL APPROACH NEW APPROACH Ma = SUPPORTABILITY (S) ? AOAO OT + ST OT + ST + TCM + TPM + A/LDT = WHERE: TOTAL OPERATING TIME DURING A SPECIFIC INTERVAL TOTAL STANDBY DURING A SPECIFIED INTERVAL TOTAL CORRECTIVE MAINTENANCE TIME DURING THE SAME SPECIFIED INTERVAL TOTAL PREVENTIVE MAINTENANCE TIME DURING THE SAME SPECIFIED INTERVAL TOTAL ADMINISTRATIVE AND LOGISTICS DOWNTIME DURING THE SPECIFIED INTERVAL HENCE, A O ADDRESSES R&M ONLY HENCE, MATERIAL AVAILABIITY REQUIREMENTS ADDRESS ALL EVENTS GIVEN: Ma OT ST TCM TPM A/LDT ========== OT + ST (?) + OT + ST + TCM + TPM + MLDT = MISSING EVENTS - SERVICING - RECONFIGURING -GROUND/CARRIER HANDLING -SET UP AND TEAR DOWN - COMBAT OPERATIONS - LAUNCH ACTIVITIES - MISSION VARIATIONS - OTHER NON R&M ACTIONS AND: S = {OPERATIONAL SUITABILITY, READINESS, SUSTAINABILITY, SURVIVABILITY, MOBILITY, LIFE CYCLE COSTS, A O } Events BECAUSE: S IS NOT ADDITIVE BUT CONSISTS OF FINITE, SIMULTANEOUS SUPPORT EVENTS FROM ALIGN TO WINTERIZE (500+ EVENTS DEFINED) SUPPORT PLANNING BASELINE (PEACETIME OPERATIONS) DESIGN FOR S BASELINE (WARTIME OPERATIONS) WHERE: f = SUPPORT EVENT FREQUENCY d = SUPPORT EVENT DURATION c = SUPPORT EVENT COST S = F (f, d, c) IS A CHARACTERISTIC OF DESIGN VS THE PROBABILITY THAT, WHEN USED UNDER STATED CONDITIONS, A SYSTEM WILL OPERATE SATISFACTORILY AT ANY TIME. A O CAN BE EXPRESSED BY THE FOLLOWING FORMULA:

3 Supportability (S) – Addressing Integration The Supportability Metric addresses EVERY support event as a DESIGN DRIVEN attribute, with respect to support event frequency, event duration, and event cost. This approach reflects an integration of quantitative and qualitative characteristics that meet specified Operational Requirements, Total Ownership Cost (TOC) goals and Performance Based Logistics (PBL). What is Supportability (S)? S = Supportability is the integrating function for all ilities with regards to design characterization, and is reflected by design features resulting from Supportability Design-to Requirements (SDTRs) S = F(f, d, c) provides the integrating function f = support event frequency (includes reliability driven events) d = support event duration (includes maintainability driven events) c = support event cost - support system cost per event (e.g. all ILS elements – facilities, training, transportability, etc.) Supportability is at its Optimum when S approaches minima, or when the system is self sufficient at least cost (therefore best value). Supportability can be expressed in terms of Total Ownership Costs (TOC) as shown below. Supportability Component of TOC: S TOC (f x d x c)

4 The Supportability Engineering Top Ten Steps 1.Establish the Project Baseline with Systems Engineering (SE) 2.Review statistical supportability drivers [S = F(f,d,c)] of Comparative Systems using Pareto Analysis 3.Review the predecessor or comparable systems technical data 4.Interview maintenance techs with SPECIFIC questions 5.Develop detailed lessons learned from steps 3 & 4 – PBL IPT. 6. Integrate technical data, statistics, and interviews - develop initial SDTRs linked to the S function. 7.Optimize SDTRs CUSTOMER criteria Technological opportunities Explore with Design Team members and Producibility Engineers to ascertain design characteristics. 8. Finalize SDTRs - use specification language 9. Update or negotiate SDTRs with SE and Designers. 10. Incorporate SDTRs into the System Specification or ECP The support scenario must focus on an attempt to eliminate the logistics infrastructure and reduce total ownership cost (TOC), which includes Depot and contractor support. PBL is applied to whats left.

6 How Should We Convey Supportability Requirements? Supportability Design-to Requirement (SDTR): The directional control computer shall contain BITE circuitry that tracks within the full range of control surface positions, and shall be impervious to variations in system ground levels (±0.5v DC). The Objective: Lets make it easy for the designer by making supportability transparent through simple and direct specifications oriented to PBL.

11 The WBS - Beyond Earned Value Reporting The Work Breakdown Structure (WBS) then: is structured to view Work Unit Codes as SDTRs can be monitored in scheduling tools (Microsoft Project) to track status of design progress to SDTRs which allows critical path identification of SDTRs Makes design appraisals more accurate and efficient Is used for Information Management Access to your data Retrieval of important information Multiple applications of your knowledge Generate schedules based on the WBS content Requirements Traceability (DOORS, SLATE, etc.) Data Base Management Knowledge Clusters Etc……

12 What about Producibility? The Producibility Design-to Requirements (PDTR) Development Process New Design Related Metrics Integrating Producibility and Supportability

13 PRODUCIBILITY DEFINED Producibility elements - major 1) Aspects of design 2) Specifications and standards 3) Materials selection 4) Processes definition 5) Environmental requirements 6) General inspections 7) Testing 8) Safety considerations 9) Cleaning requirements

14 AND THIS Producibility element - subordinate 1) Documentation control and administration 2) Piece part/minor fabrication 3) Assembly and test 4) Integration and performance checks 5) Personnel characteristics 6) Facilities/equipment/transportation Again, just as in Supportability, we compute: Weighted or relative importance of elements for system being replaced or modified - Comparison Baseline Weighted or relative importance of elements that we want to see in the new system- The New Project

15 PRODUCIBILITY DEFINED (surprise - same as Supportability!) Producibility is defined as : The frequency of the manufacturing event where f = manufacturing event frequency; i.e., how often will it occur? The duration of the manufacturing event where d = event duration; i.e., how long is the event? The cost of the manufacturing event where c = event cost; I.e., how much will it cost? P IS AT ITS OPTIMUM WHEN P IS MINIMIZED OR WHEN PRODUCTION IS MOST EFFICIENT, EASY TO ASSEMBLE, AND AT LEAST COST

16 Producibility Integration Process Evolving designs are optimized for producibility Producibility Design-To-Requirements (PDTRs) provide comparison basis against Predecessor PDTRs serve as guidelines during the Technology Insertion Process to ensure technology does not proliferate producibility risks Maximize producibility/supportability synergism Simulate factory flow optimization after PDTR implementation to determine PDTR effectiveness Incorporate PDTRs into the Technical Data Package so as not to lose them when you create a build package for re-procurement A disciplined, systematic approach enhances Producibility Implementation

P = F(f, d, c) Producibility is a metric with respect to production event frequency, duration, and cost that reflects composite characteristics of the manufactured system (project), to meet specified quantity, schedule and production standards.

19 Summary Supportability (S) and Producibility (P) may be redefined as the integrating functions, represented by all ILS elements, that addresses all support events related to the design of the system such that Supportability is a Function of: f = Support or Production event frequency d = Support or Production event duration c = Support or Production event cost per event This function can be used in Pareto analyses of an existing, baseline or comparative system to determine the drivers (f,d,c), which also include MTBF and MTTR. Those same drivers are then intentionally reduced by design-collaborated SDTRs for each event. Design responses to each SDTR are tracked and assessed for the entire system. When (S) and (P) approach minima, the system is said to be self-sufficient and in an ideal state. Support event frequency, duration and cost can be independently defined, and using a life cycle cost model such as CASA, the impact on cost can be immediately determined.

20 CONCLUSION Integrate Producibility and Supportability design-to results into a systems engineering requirement. We must: Extend Supportability beyond traditional metrics (MTBF, MTTR, etc.) Define NEW metrics: Producibility - Supportability Develop requirements written in design-to language Address Readiness, Sustainability, Mobility, Transportability and Operational Availability via SDTRs Use the Work Breakdown Structure (WBS) as an Information Node for requirements development and tracking Support by Design is the Key - through Supportability and Producibility Design-to Requirements (SDTRs and PDTRs), resulting in: Low Maintenance Man Hours per Flight Hour (Mmh/FH) Reduced Cycle Time Reliability and Robustness Reduced Logistics Foot Print Supportable and Producible Products
