In the world of systems engineering, the importance of having high quality requirements is well known and that is why there are standards and guidelines that establish the characteristics that the requirements must have for considering them of good quality. To obtain quality measurements of the requirements it is common to use quantitative quality metrics based on established standards. However, the risk is to build assessment methods and tools that are both arbitrary and rigid in the parameterization and combination of metrics. This webinar is focused on the presentation of a flexible method to assess and improve the quality of requirements that can be easily adapted to different contexts, projects, organizations and quality standards, with a high degree of automation. In the method pro...

Upon landing in Mexico, Conquistador Hernán Cortés famously ordered his men to “burn the boats”. For the same reasons, our journey towards Model Based System Engineering (MBSE) will require the burning of the specification “document boats” used to house and transport the most important artifacts; i.e. the declarations of Stakeholder Needs and System Requirements. No doubt, prior to burning the boats, Cortés had to commit to benefits great enough to obtain the resources required to succeed. Analogous planning must be done to embark on a MBSE expedition that includes transformations in Requirements Management. To this end, this presentation will offer a benefits analysis and realization plan (in the form of a metamodel & tool demo) that may be useful in planning your MBSE expediti...

Traceability is a core activity within the System Development Lifecycle, although a tedious and time-consuming task, especially when the traces involve items coming from different disciplines and tools. Therefore, teams must be provided with tools that allow connection to heterogeneous environments, allowing easy access to the definition of traces, management of traceability matrices and impact analysis, and providing also smart analysis tools to suggest missing traces and suspect links. Finally, all this information must be exported in a flexible, and easy-to-understand yet accurate way. In this webinar, The REUSE Company will present the first version of its brand new tool TRACEABILITY Studio. This tool, fully integrated with the Systems Engineering Suite, provides an easy-to-use answer...

In this era of Lean and Agile principles we tend to focus on collaboration, team cohesion and customer value, so where do requirements come in and how can focused requirements engineering contribute to increased customer satisfaction? It does not matter what type of engineering principles you stick to, if you do all the work in a single team, larger organisation or let someone else deliver the product or service, it all comes down to the same issues of understanding the need and delivering a solution to it. This webinar will show how requirements are the mean to the end of achieving increased customer satisfaction and the key is a changed view on the importance of requirements being the messenger between all stakeholders. Topics: Customer satisfaction is a phrase often used and perhap...

ECSS - European Cooperation for Space Standardization- represents a set of standards aiming to gain a common understanding across the space industry in Europe. ECSS released the ECSS-E-ST-10-06C (6 March 2009) to provide some guidelines for the development of technical requirements specifications. The REUSE Company has developed a Knowledge Library coping with the ECSS standard (among others within the ECSS) to guide requirements writers writing high-quality requirements and provide help during the long-lasting requirements inspections, those making easier the compliance with the ECSS standards. This Knowledge Library is part of the SES Suite (Systems Engineering Suite), managed by our tool Knowledge Library (including glossaries, taxonomies of terms, taxonomies of types of requirements, ...

Ambiguity is a factor that can jeopardize the optimal development of a project, as decisions over the requirements statement are made subjectively. And luckily this aspect can be under control if we apply Systems Engineering centred on Knowledge and Quality to develop better assets of information during the project lifecycle. There are four main aspects that aids KCSE (Knowledge Centric Systems Engineering) implementation within an organization: - Discovering Information in Requirements Documents - Controlled information to unify requirements interpretation - Identifying weaknesses and challenges in requirements documents - Building up the Knowledge Base or Ontology Verification analysis: Smarter and Quicker

Requirements are, with no doubts, the main source of re-work in both software and systems intensive projects. This webinar introduces these sources of problems and misunderstanding, and provides a set of basic tricks and techniques to overcome the problems and provide error-free requirements specifications to properly set the roots of successful projects. All these basic aspects of requirements quality will be covered using a default installation of the tools VERIFICATION Studio and the Rich Authoring Tool.

Competition in a fair and transparent manner is the heart of procurement, that is why you probably already have a process in place to ensure the legal aspects of Fairness, Integrity and Transparency through the competition. But what about the two other corner stones and key guiding principles of Economy and Effectiveness, and not least the principle of Best value for money? The Procurement Quality Suite (PQS) guarantees that the purchasing body is conducting the procurement process with maximum effectiveness in relation to the overall budget, and that the principle of Best value for money is indisputably and crystal clear from the initiation of the procurement project, through requirements definition, strategy selection and finally, bid evaluation and selection. PQS consists is an appli...

A recent blog post by our esteemed colleague Christer Fröling has sparked a tidal wave of interest and his paper “NLP beats DXL (DOORS scripting) every day of the week” has been distributed widely. But can his claim be substantiated? Dr. Simon Wright will investigate this claim during a webinar and examine the evidence. As someone who has been involved in improving requirements quality for over 20 years and as a DXL programmer for over 10 years he is ideally placed to referee this match, DXL verses NLP. During the webinar he will briefly review the development of Requirements Quality Tools and draw out the salient features that are needed to effectively and efficiently undertake NLP. He will explain the differences between textural analysis, syntax checking, semantic checking, corre...

In the world of Model-Based Systems Engineering, we usually find a huge ecosystem full of tools. The community of practitioners will be using a wide variety of different tools for Requirements Management, Logical and Physical Modelling, Traceability, Simulation, Quality Management etc. With regard to Quality Management, System Quality Analyzer (SQA) performs requirements quality assessment based on the Correctness, Completeness & Consistency (CCC) approach, that is, automatic verification of your requirements and support to requirements authoring. For this purpose, the SQA knowledge base (ontology) can be customized to automatically include -in real-time- the content of Rhapsody models or Simulink files or even external ontologies created with Protégé, among others, so that requirements...

Model-Based (MBSE) is the current trend in regard to Systems Engineering, leveraging testing and simulation activities. However, it’s also clear that textual requirements will remain in the scene since they are also key for testing, certification, and communication with other stakeholders. This Webinar describes a real scenario where, while working in a model-based project using Rhapsody, there is the need of writing high quality requirements concerning the UML/SysML elements of the project. In this scenario where UML/SysML models coexist with requirements, a crucial role is played by physical models simulations, indeed requirements feasibility is going to be tested against physical models simulation (FMUs files).

Model-Based (MBSE) is the current trend in regard to Systems Engineering, leveraging testing and simulation activities. However, it’s also clear that textual requirements will remain in the scene since they are also key for testing, certification, and communication with other stakeholders. This Webinar describes a SMART way to mix both models and textual requirements together, covering topics such as requirements transformation (from requirements to models and vice versa, from requirements to test cases…), traceability of different sorts of items, retrieval and reuse of work products… All these topics will be addressed having in mind the importance of quality standards, since are the key for systems certification, and fully required to always reuse, trace and transform high-quality ...

Nowadays, very few companies develop, distribute, and sell products end-to-end. On the contrary, it’s quite common to find the supply chain approach, where many suppliers might be involved in the whole product lifecycle. This may lead to specialization, cost reduction, and scalability. This Webinar focuses on the close communication between the OEMs (Original Equipment Manufacturers) and the Suppliers to perform quality assessment and keep track of the evolution of the quality of the supplier assets. In a nutshell, OEMs will define the quality metrics that must be fulfilled by the different Suppliers along the supply chain. Suppliers will develop their specifications, performing also quality assessment, and will send quality reports to the OEM. With this information, the OEM tracks the...

Completeness is, by far, the most difficult quality characteristic to be checked in our requirements specifications. Completeness is a twofold issue. On the one hand, a requirement statement is complete when it includes and conveys all the information it has to include: who is the subject of the action, when is this action performed, under what conditions, what should be the performance…. In other words, and citing the INCOSE Guide for Writing Requirements, a requirement statement is complete when it “… describes the necessary capability, characteristic, constraint, or quality factor … without needing other information to understand the requirement”. On the other hand, the entire specification should be analyzed in terms of completeness to answer questions such as: Are we consi...

Writing correct requirements is, sometimes, a challenging task. However, there are plenty of resources publicly available including tips on how to write correct requirements; we in The REUSE Company also provide our own guide (RQS tips summary), training and tools (RQA and RAT). Once the correctness topic is properly addressed, the real problem when analyzing the overall quality of a project (in terms of its requirements) comes with the consistency among the different requirements, that many times are written by different people, in different places… Not to mention the consistency between requirements and models in a MBSE environment. This webinar focuses on the analysis of requirements consistency, and the metrics provided in Requirements Quality Suite to deal with this topic.

When you are bidding in a public tender, every minute counts. Even for the more experienced analyst, the short time that is available makes it very difficult and risky to come up the right bid, the one that presents the best budget by maximizing existing asset reuse. You need to quickly identify those tender areas which can be matched to what you have developed or built before and, in addition, those areas that you haven't seen before. Wouldn't it be nice if you could shorten your public tender or RFP analysis with the help of The Reuse Company tools to: - Quickly parse the tender - Pre-allocate or cluster requirements according to specific criteria - Compare tender requirements with your existing assets to determine what has been previously developed or built and therefore make a more edu...

Finding the proper set of quality rules to be checked in our requirements documents is key for the success of our projects. RQA (Requirements Quality Analyzer) allows you an easy translation between paper-based quality rules and checklists into an automatic tool to help quality teams and requirements authors. RQA includes, out-of-the-box, a wide variety of requirements quality metrics. However, in some cases, the metrics to follow have to be tailored for particular cases and the out-of-the-box metrics could be not sufficient. This Webinar shows how a set of parameterized metrics can help to create custom metrics easily. All this custom metrics are automatically and seamlessly integrated together with the rest of out-of-the-box metrics and are accessible in both RQA and RAT (Requirements Au...

In this webinar we will show how KM (Knowledge Manager) can be used to easily create and manage requirements patterns. RAT (Requirements Authoring Tool) will also be shown briefly to exemplify the writing of a new requirement based on one of the patterns created during the live demonstration, and how to apply requirements patterns for an automatic extraction of requirements from an unstructured source. Finally, we will also show how RQA (Requirements Quality Analyzer) can make use of those patterns to leverage the use of the quality metrics, and to extract content suitable for the knowledge base (domain concepts and relationships among concepts, properties…). RQA, RAT and KM are the tools included in the Requirements Quality Suite (RQS).

Checking and enhancing the quality of requirement specifications is a vital task for ensuring a successful outcome of a project. Out-of-the-Box the Requirements Quality Analyzer (RQA), and the Requirements Authoring Tool (RAT), help the user to avoid the most common and most annoying mistakes found in requirements. During this webinar we will explain and demonstrate the mechanisms offered by the RQS Tools to deal with the bulk discovery, capture and management of knowledge, and how sources of knowledge in current, or even previous projects can be used to ease this process.

This completeness metric compares the number of terms that are covered in the requirements specification with a selection of terms from the terminology layer of the System Knowledge Base (SKB)

This completeness metric compares the number of relationships that are found in the requirements specification with a selection of relationships from the Breakdown structure of the System Conceptual Model (SCM) layer of the System Knowledge Base (SKB)

This completeness metric compares the number of different Relationship Types (NOT relationships instances) that are found in the relationships extracted from the requirements specification with a Relationship Type selection set from the Conceptual Model layer of the System Knowledge Base (SKB)

This completeness metric compares the number of Relationships that are extracted from the requirements specification (through requirements patterns formalizations) with the Relationships that are extracted from a set of models stored in the Conceptual Model layer of the System Knowledge Base (SKB)

This completeness metric compares the number of different Properties that are found in the formalization from the requirements specification with a Properties set from the Conceptual Model layer of the System Knowledge Base (SKB)

This completeness metric compares the number of Requirements Patterns that are extracted from the requirements specification with the number of Requirements Patterns that are selected from the Patterns layer of the System Knowledge Base (SKB)

This completeness metric analyzes the not existence of links between requirements expressing the same need at the different level of abstraction in different modules/blocks of the same project.

This consistency metric compares the values of properties extracted from the specification with the values assigned to the same property stored in the Conceptual Model layer (SCM) of the System Knowledge Base (SKB)

This completeness metric compares the values of properties from the parts of a breakdown structure with the value of the property from the composite. The selected breakdown is stored in the Conceptual Model layer (SCM) of the System Knowledge Base (SKB)

This consistency metric compares several requirements from same or different specifications, representing the inconsistency ratio for requirements expressing the same need at the same level of abstraction

This consistency metric checks if the requirements from the same specification use different measurement systems (i.e. International system, British Imperial system, etc.). Therefore, it detects measurement systems’ incompatibilities for the magnitudes selected by the user. I.e.: Distance/Length – IS [Kilometers] or BIS [Yards]?, Weight – IS [Kilograms] or BIS [Pounds]?, etc.

This consistency metric checks if requirements from the same specification use different measurement units (i.e. ‘Kilograms’, ‘Pounds’, etc.) for a specific element’s property. Similar to the Measurement Units Consistency Metric, this one detects measurement units’ inconsistencies for a property of a element selected by the user. I.e.: Fuel tank – Capacity – Liters or Cubic Meters?, Aircraft – Weight – Kilograms or Pounds?, etc.
