RQA - QUALITY Studio

The SMARTer way to manage the quality of your work products

RQA

Requirements Quality Analysis. Quality Analysis of Models and Documents

RQA – QUALITY Studio

Poor quality of engineering items during the concept and design phases of a project leads to rework, extra costs, delays and, if not detected, severe consequences. A tool to automate the routine quality inspection and analysis of different types of engineering items minimizes the cost of quality appraisals, while increasing the consistency and overall quality of the projects.

Defects can be caused either by inadequate engineering decisions, or by the incorrect representation of engineering information in requirements, models, etc. Automatizing the quality inspection activities will give engineers more time for better decision making while providing means so that no defect remains hidden.

Natural Language Process and Artificial Intelligence provide a semantic analysis towards more accurate inspections.

Benefits

Quality

While performing the quality analysis, RQA – QUALITY Studio analyzes engineering items using the agreed best practices, rules, checklists, policies, etc. identifying defects, inconsistencies, and incomplete information.

Time

Automatizing extremely time-consuming tasks will reduce the time spent on analysis, simulations, test, inspections, etc.

Money

Reducing rework (and consequently costs) caused by flaws at all levels in your system engineering items can be achieved by automating peer-reviewing and quality analysis.

Descriptions

 Quality Analysis of Requirements and all Kind of Engineering Items

The current version of RQA – QUALITY Studio extends the quality analysis concept and now covers all the engineering items generated during the systems engineering life cycle. Quality must be managed not only within requirements, but also within logical models (UML or SysML), physical models (MODELICA, Simulink, etc.), 3D models, test cases, FMEA tables… and even textual documents (e.g. a SEMP): all these types of engineering items can now be analyzed with RQA – QUALITY Studio.

Customizable Quality Functions

Different companies, different industries, methodologies and types of projects, different types of documents and diagrams at different levels of abstraction?

RQA – QUALITY Studio is the tool that can cope with this plethora of different engineering items, methods, processes and tools. RQA – QUALITY Studio provides tailored analysis and configurable assessments, represented in a centralized system quality scoreboard, with the intention to provide a quick understanding of the current quality status, and quality evolution of a project.

Reduces the defects introduced during Requirements and Design phases

Close to 90% of the defects are introduced during the Requirements and Design phases. However, only 20% are actually discovered.

RQA – QUALITY Studio (in combination with RAT – Authoring Tools) reduces the defect rate and boost the early detection, thus reducing cost and increasing overall quality.

Features

Correctness, Consistency and Completeness in RQA - QUALITY Studio

RQA – QUALITY Studio provides means to connect to a large number of engineering tools (requirements management tools, UML/SysML modelling tools, simulation tools, MS Excel sheets, MS Word documents…), retrieving the key elements managed on those tools, and providing an automatic inspection based on the CCC criteria.

CCC Correctness, Consistency and Completeness– are the three key elements to provide a thorough quality inspection of any engineering artifact. While Correctness is focused on the quality of individual items, Consistency and Completeness take a whole document (document, specification, model…) or set of documents to detect missing elements, as well as the lack of consistency among them.

Requirements Quality Analysis in RQA - QUALITY Studio

RQA- QUALITY Studio provides hundreds of quality metrics to analyze different types of requirements repositories: IBM DOORS (both classic and NG), PTC Integrity Lifecyle Manager, 3D Experience Requirements Manager, CATIA Reqtify, Visure Solutions, MS Excel, ReqIF and OSLC compliant information sources.

These metrics cover the CCC approach and include extensibility mechanisms which extend the number of metrics by using parameterizable metrics (metrics that can easily be configured by the end-users), custom-code metrics (metrics which can be coded by advanced end-users), and checklist-based metrics (which enable a manual-oriented inspection).

The Concept of Quality Project

RQA QUALITY Studio uses the notion of Quality Project to manage the quality of large and heterogeneous sets of engineering items in one single inspection process. A Quality Project calculates and manages the quality of a set of requirements modules, architectures, models, documents and all sorts of engineering items, allowing a proper and global quality management activity. A Quality Project, which might contain requirements documents, UML/SysML models, physical models, textual documents, spreadsheets…, will not only provide correctness checking, but also an overall completeness and consistency check.

Moreover, since no two projects are alike, and no two pieces of the same projects are alike, RQA – QUALITY Studio allows a flexible mechanism to assess different elements within the same Quality Project with a different combination of quality metrics.

RQA - QUALITY Studio and the Supply Chain

RQA – QUALITY Studio offers functionality to reduce the interactions between OEMs and suppliers throughout the supply chain by allowing all parties to share a common quality view. OEMs can establish a set of metrics in RQA – QUALITY Studio (a quality certificate) and share this certificate with everyone in the supply chain. After that, the OEM can receive periodic quality reports from the supplier allowing the visualization of the results using a simple procedure.

Libraries

Safety-critical systems must normally comply with standards. Beside the out-of-the-box standard metrics, other libraries are available from The REUSE Company’s website: the rules described in the INCOSE Guide for Writing Requirements, the recommendations in NASA’s Systems Engineering Handbook, the requirements patterns defined by EARS (the Easy Approach to Requirements Specification) and the glossary, patterns and quality rules defined in the ECSS-standards followed by the European space industry. You can also create your own set of metrics and share it in the form of a quality library.

New Natural Languages

The current version of RQA – QUALITY Studio can analyze textual artifacts written in: English, French, German, Japanese, Spanish, Swedish, Italian, and Dutch.
