Our supportability engineers use wide range of analyses that are conducted within the systems engineering process. The goals are to ensure that supportability is included as a system performance requirement and to ensure the system is concurrently developed or acquired with the optimal support system and infrastructure. The analyses include the integration of various analytical techniques with the objective of designing and developing an effective and efficient Product Support Package. The primary techniques used in analyses are: Failure Mode, Effects and Criticality Analysis (FMECA), Fault Tree Analysis (FTA), Reliability Centered Maintenance (RCM) Analysis, Level of Repair Analysis (LORA), Maintenance Task Analysis (MTA), and core logistics analysis, source of repair analysis, and depot source of repair analysis.

Reliability, Availability & Maintainability (RAM) Analysis

At QVISE, our RAM Experts conduct Reliability Availability & Maintainability (RAM) Analysis in compliance with MIL-STD-1543B, MIL-STD-785B with the current “DoD Guide for Achieving Reliability, Availability & Maintainability Analysis” that illustrates the time-frame at which the essential steps should be conducted. Our analysts follow these steps:
(1) Understand and Communicate User needs and Constraints;
(2) Design and Redesign for RAM;
(3) Procedure Reliable & Maintainable Systems and
(4) Monitor Field Performance.
For that purpose, our RAM analysts make use of the RAM toolkit that makes it easier to navigate and select the tools appropriate for the task.

Failure Mode,Effect & Criticality Analysis (FMECA)

QVISE understands the price & loss of having an equipment failure / breakdown due to poorly or inadequately designed maintenance processes. Therefore, our specialist Engineers have extensive experience in conducting FMECA with MIL-STD-1629A, TM 5-698-4 and ‘The new SAE FMECA standard’. QVISE has software tools to conduct FMECA (Quantitative & Qualitative both) to identify probable risk and devise mitigation plan. We provide guidance on when to perform the task and to what depth, to go along with the analysis. Our experts initiate the process by first defining system / functional requirements and mode of operations, then developing reliability models and defining item failure mode(s) followed by the Criticality analysis either Qualitative or Quantitative as per the consumer demand. The FMEA/FMECA is conducted on ASENT and Relyence which also assists in conducting Fault Tree Analysis. We illustrate the functional block diagram, following the RBD, conducting FMEA and Criticality analysis.

Reliability Centered Maintenance (RCM) Analysis

Our experts have had vast experience and are conditioned to follow eitherMIL-STD-3034A or MIL-STD-2173, NAVAIR 00-25-403 (as per customers’ requirement and needs) and SAE J1012 “Reliability Centered Maintenance” for a systematic approach in identifying preventative or scheduled maintenance tasks for an equipment/end item by following RCM decision Logic Tree and establish necessary preventative (or scheduled) maintenance task intervals. In RCM, we achieve improvements through maintenance optimization such as establishing safe minimum levels of maintenance, changes to operating procedures and strategies and the establishment of capital maintenance regimes and plans. Successful implementation of RCM in all our projects has led our clients to increased cost-effectiveness, machine uptime, and a greater understanding of risk level. The analysis results provide a clear decision as to which preventive maintenance tasks should be conducted to manage & optimize system availability – be it a preventive or predictive (condition-based) maintenance.

Maintenance Task Analysis (MTA)

Our maintenance engineers are tuned up with MIL-STD-1478 to conduct MTA by defining a step-wise procedural approach required to undertake any maintenance task. During the identification of all the steps (each subtask), our analysts effectively lay down all the requirements to perform that task; ranging from Spares, Materials required by that task, Tools & other Support Equipment needed, the personnel(s) required to perform that task and to any ashore Facility (with the controlled environment) required to carry out / perform that Maintenance Task. Once MTA has been performed for all Maintenance Significant Items (MSls), the results are a complete identification of all the physical resources that must be available to support that system. The MTA results are documented in a Common Source Database (CSDB), i.e., LPD (Logistic Product Data), that can then be used to quantify the support requirements for that system.

Training Needs Analysis (TNA)

During the conduct of MTA (Maintenance Task Analysis), our experts also identify the gaps between employee skill level and the skill level required due to the new equipment/platform's induction. To identify those exact training requirements, Training Needs Analysis is conducted. This involves a series of steps that reveal whether the training will help solve the identified problem(s) or needs improvement. The training can be described as “the acquisition of skills or improvement within the performance.” Training requirement includes (but is not limited to) existing skill level/qualification required to undergo requisite course, contents of the course, number of days for the course and final skill level achievement.

Level of Repair Analysis (LORA)

QVISE provides LORA services in two steps. Initially, we provide Non-Economic LORA decisions based on the customer’s criterion to make initial support decisions. We then use an Economic model/cost model to determine the most cost-effective alternative. Based on MIL-STD-1390D, we describe the unique models, which various military services put to use, but at the same time reflecting the client’s maintenance philosophy, making the model client specific. By culminating all maintenance planning activities through which levels of maintenances are determined (i.e., organizational, intermediate and depot) and producing the system's final support solution.

We use the LORA toolkit to portray and compare alternative hardware design with supportability or acquisition options. It can be used for any hardware decision with downstream or life cycle economic implications. Primarily identifying the LOR options for all removable parts (each item) in the hierarchical structure that are collectively aimed at minimum lifecycle cost with achieving the system’s targeted Operational Availability as per the client’s requirement.

Life Cycle Costing Analysis (LCCA)

Life cycle costing is the total cost of a project over its full life, including the cost for Research & Development, Testing, Production, Facilities, Operations, Maintenance, Personnel, Environmental Compliance and Disposal. Therefore, QVISE understands the need for LCCA by using state-of-the-art Life Cycle Analysis Software Toolkit by implementing the best practices. This Toolkit has the ability to evaluate the resource and cost implications of the Deployment, Operation & Support of complex evolving systems in dynamic operating scenarios. It Provides unparalleled decision support, including; System selection, Operational planning, Support planning, Resource management, Capability planning, and Budget planning as well.

Failure Reporting, Analysis and Corrective Action System (FRACAS)

FRACAS provides our IPS Managers visibility and control over Reliability and Maintainability. Our Engineering experts use FRACAS in compliance with MIL-HDBK-2155 to be coordinated and integrated with other program efforts such as Reliability, Quality Assurance, Maintainability, Human Engineering, System Safety, test, parts, materials, & processes control, Configuration Management, and Integrated Product Support to preclude duplication of effort and to produce integrated, cost-effective results.

At QVISE, we provide FRACAS to our clients to improve hardware and associated software by timely and disciplined utilization of failure and maintenance data to generate and implement effective corrective actions to prevent failure recurrence and simplify or reduce the maintenance tasks.
