Department of Defense DoD It is the opinion of the author that the TEMP document does not constitute a satisfying basis for strategic VVT planning of engineered systems. This is because: 1 it deals only with the Qualification phase of systems development, 2 it is quite general thus difficult to put into practical use and 3 it contains great amount of jargon unique to the US-DOD.
This VVT-MP guide provides users with guidance concerning the preparation of a master plan for planning strategic VVT processes in medium to large projects. Please note the following:.
The scope of the document is to provide a template to help VVT engi- neers and managers responsible for VVT to plan the VVT process as well as determine the cost and other resources associated with all VVT activities in projects.
The project manager or any appropriate functionary should nominate a person who will be responsible for creating and maintaining the VVT-MP based on data gathered from all relevant stakeholders of the system. Such definition determines the overall set of VVT activities and the level of performance 0.
This VVT performance level shall be captured in appropriate tables. Choosing the specific VVT strategy must be based on the characteristics of the project and must be translated into specific VVT activities. Such activities would be carried out either by VVT personnel organically attached to the VVT team or by other engineers and professionals who are doing a certain level of VVT activity as part of their regular assignments e.
These forms shall define all the relevant parameters associated with the performance of the specific VVT activity. However, during earlier stage of the VVT-MP, only the more rudimentary and available information about the testing should be filled in, such as the system and subsystem involved, the VVT activity name and objective and the responsible person.
Chapter 1 of the VVT-MP shall provide a brief description of the mission and the system as well as a set of critical technical parameters of the system. This section shall also include a description of the operational and logistical environment envisioned for the system. Key features and subsystems, both hardware and software such as architecture, interfaces and security levels , allowing the system to perform its required operational mission.
Interfaces with external systems existing or planned that are required for mission accomplishment. A diagram should show the system inter- faces with the external environment.
Critical system characteristics or unique support concepts resulting in special test and analysis requirements e. A list of the main operational capabilities required for accomplishing the mission e. A matrix depicting the critical technical parameters of the system see Table B.
This threshold or value should reflect the level of perfor- mance necessary to satisfy the desired capabilities.
System definition System design System. The schedule shall show how VVT activities synchronize with the project plan. The main project engineering activities and the major milestones shall be identified. Subordination of different teams system engineering, quality assurance, integration, etc. Responsibility of all participating organizations involved in the VVT process e. This chapter shall describe the specific VVT strategy adopted for the project and the resulting VVT activity planning, events and scenarios emanating from the selected VVT strategy.
Finally, the VVT limitations shall be discussed. In general, the set of VVT activities may be divided into the following three categories:.
Preparing VVT products 2. Applying VVT to engineering products 3. Definition Qualification Design Integration Implementation. Table B. It presents a generic maximal set of VVT activities, as described in this book i. The intent of these forms is to provide the means by which the VVT planner can identify the specifics of VVT activi- ties as well as relevant information such as VVT method, support equipment, schedule and budget of each planned VVT activity.
A complementary test will be performed during Qualification phase as part of the planned system test flights. Digital Integration Laboratory 2. Radar target simulator Relevant documents: 1.
Radar system specification—A 2. This chapter shall summarize the resources and budget required in order to fulfill the planned VVT program. In particular, this section shall summarize the following resource categories. If key subsystems components, assemblies, subassem- blies or software modules are to be tested individually before being tested in the final system configuration, then each subsystem and the quantity required shall be identified.
In addition, when prototype, engineering models or pro- duction models shall be used for a given VVT activity, they shall be identified in this master plan.
The VVT planner shall compare the requirements for test ranges or facilities dictated by the scope and content of planned testing with existing capability and highlight any major shortfalls, such as inability to test under representative natural environmental conditions. In addition, the VVT planner shall explain how these models and simulations shall be used as well as identify the resources required to accredit their usage.
Individual budget figures shall be extracted from the various VVT planning forms discussed above. Open navigation menu. Close suggestions Search Search. User Settings. Skip carousel. Carousel Previous. Carousel Next. What is Scribd?

Verification, Validation, and Testing of Engineered Systems (eBook, PDF)
A guide to systems engineering that highlights creativity and innovation in order to foster great ideas and carry them out Practical Creativity and Innovation in Systems Engineering exposes engineers to a broad set of creative methods they can ado For the past twenty years, he has worked for Israel Aerospace Industries, where he has managed large software projects. Engel was involved with several research projects funded by the European Commission. He is currently teaching systems engineering courses at the Holon Institute of Technology in Holon, Israel. Preface xvii Part I Introduction 1 1. Introduction 3 1.
Notably, quality-cost expended on performing VVT activities and correcting system defects consumes about half of the overall engineering cost. Verification, Validation and Testing of Engineered Systems provides a comprehensive compendium of VVT activities and corresponding VVT methods for implementation throughout the entire lifecycle of an engineered system. In addition, the book strives to alleviate the fundamental testing conundrum, namely: What should be tested? How should one test? When should one test? And, when should one stop testing?

This VVT-MP guide provides users with guidance concerning the preparation of a master plan for planning strategic VVT processes in medium to large projects. Please note the following:.
The book is organized in three parts: The first part provides introductory material about systems and VVT concepts. This part presents a comprehensive explanation of the role of VVT in the process of engineered systems Chapter The second part describes 40 systems' development VVT activities Chapter-2 and 27 systems' post-development activities Chapter Corresponding to these activities, this part also describes 17 non-testing systems' VVT methods Chapter-4 and 33 testing systems' methods Chapter
All course material and assignments will be provided using the ecampus features. Schedule: Tuesdays to pm Location: WVU ecampus, Office Hours: Upon Request Course Objectives: The objectives of this course are to evaluate verification and validation theory and practice from a software engineering perspective, research the history, principles and techniques of verification and validation across varied software domains, and apply verification and validation techniques and practices to various software artifacts across the development life cycle for both large and smaller software systems. Demonstrate the application of verification and validation tasks and their outcomes during the software life cycle. Compare and Contrast the theoretical and practical limitations to software verification and validation analysis.
