Requirements Engineering and Management

Good Requirements Engineering and Management is a critical success factor for the efficient development of complex systems. This includes both Requirements Engineering and measures to control, monitor, and administer requirements.

Challenges and opportunities

EVOCEAN guides customers in the improvement and in establishing requirements engineering and management practices. A broad and extensive experience in various sectors allows us focused and customer specific guidance.

To respond to today’s needs for product development, simply making lists of the requirements is no longer enough. The increasing complex, dynamic and fluid situation can only be addressed with comprehensive, tool-supported Requirements Engineering and Management. This is required to keep control of risk, manage change and monitor implementation.

EVOCEAN maintains a close cooperative relationship with best-in-class manufacturers of Requirements Management Tools. When combined with our experience in Requirements Engineering, this allows us to offer our customers sustainable, profit-enhancing solutions.

Competence Center Requirements Management
Increasing efficiency through agile requirements

In our fast-moving world it is difficult to define all requirements for future products and services upfront. Further, driven by the integration of additional functionality and performance needs in products, the competitive environment is becoming even more dynamic. At the same time we are confronted with new technologies, customers and competitors as well as with changing standards and regulations. To cope with these challenges successfully, agility in requirements management is beneficial. We can help you!

Agile requirements analysis and documentation, which enjoy increasing popularity, deviate in some points from the classical approach. EVOCEAN helps you to find pragmatic approaches (classical and agile) which correspond best with your development organization as well as with the standards relevant for you.

Formulating & Managing Requirements – Best Practices

Various practices for requirements management are surely already in use in your company. We help you to identify best practices, to optimize them and to establish them throughout the company.

Identify customer requirements: with the help of different techniques, which optimally correspond to the abilities of your team, the requirements of your systems, as well as to the culture of the various stakeholders. Use Cases, interviews, templates and other “tools” support the communication between the various stakeholders.
To refine customer requirements into the developer’s language: define terminology and level of detail for every requirement type in order to write clear and precise product specifications.
Verify that requirements are traceable, unambiguous, clear and testable: for example with check lists, reviews or analysis models (UML/SysML).
Manage requirements and their changes throughout the project lifecycle; to enable traceability, in order to ease analysis and valuation of impact of changes on the projects.
Agile and Lean Methods Applied to Requirements Management

In fast changing projects, experimentation must be built into the development process; also because it is usually not possible to fully define the product at its inception. In order to implement the feedback of the product owners early in the process, complex products must be split into understandable parts and be developed in fully functional iterations.

Approaches for agile requirements management:

  • Requirements for the product as well as their value for the users are formulated by “Product Owner”
  • The requirements are managed according to their market value.
  • The relative priorities of the requirements are set at the start of each iteration (sprint), taking the changes and learning effects into account from the previous sprint.

Approaches for a lean requirement management:

  • Eliminating ballast in the requirements management; for example by writing requirements by cross-functional teams – for better communication.
  • Promoting learning practices; by using iterative development to enable teams to get to know the demands of the stakeholders and to act accordingly.
  • Integrating quality in the process; by applying standards and compliance right from the beginning into the process.
  • Teams organize themselves; so that the most important requirements are fulfilled first.

Techniques and Tools for Compliance with Standards

To cope with standards such as CMMI, IEC 62304, IEC 61508, ISO26262 etc.  supporting tools are very beneficial. In order to guarantee the required traceability and documentation of the development process on one side and on the other hand, also to efficiently realize the requirements with modeling into the design. The tools also help that products are completely specified and that the product, the tests and the risks are traceable to all requirement levels. A major benefit of tool support is the easy impact analysis of changes.

EVOCEAN supports you to evaluate and implement corresponding tools and technologies with the aim to improve your processes and to raise your development efficiency, thus minimizing risk and cost. Our expertise is based on years of experience with many known tools in various domains as well as on practice-oriented knowledge.

Developing complex systems efficiently (mechanical components, hardware or software chips) from the multi-layered requirements, nowadays the functional modeling with SysML is used increasingly.

Your advantage

Agile requirements management is a logical advancement with respect to the classical approaches corresponding to actual needs of our time. The simple and in itself consistent approach allows you to develop new products with minimum effort and risk, according to market requirements and creating space for innovation!

Digital Adoption

Digital Adoption Platforms to empower the user in the digital World

Digital interaction in the workplace and also in everyday life is becoming more and more the status quo. At the same time excellent user experience and promoting feedback is becoming ever more important. This is especially true for organizations to learn faster as they evolve at increasing pace.

Systems Engineering

Products are more and more complex and interconnected. With the uprising of the Internet of Things (IoT) and the opportunities given by the digitalisation of the Product Life Cycle, aka. Digital Transformation and Digital Twin, addressing better ways is becoming ever more important.

Systematic Requirements Management for Effective Development Projects

Taking the right product to market at the right time is a decisive factor for success in today’s competitive environment. Development processes must return results fast, without compromising on quality or deviating from the requirements profile. They must further be designed to allow a fast response to changing market needs. It should also be easy to improve new products after they have been launched. The dynamics and changes cannot be handled any more effectively in Word or Excel based requirements solutions. Capturing, managing, tracking, analyzing requirements easily and in a manner that they can be communicated and tested effectively is key to success.

Managing requirements efficiently

These claims can only be met by adaptive and efficient Require-ments Management & Engineering (RE): from capturing, organizing, versioning, publication and monitoring to change and impact analysis of requirements.

The following three points are critical to success:

Requirements and their test criteria must be understandable, testable, unambiguous, feasible and consistent.

Not all requirements are equal. Priority, weighting, and risk assessment are important attributes for effective planning of re-sources.

Requirements must be traceable. This is the only way to ensure that the effects of new needs can be analyzed and calculated and that certification needs are met.

The latter point is becoming ever more important as the reuse of systems, integration of new functionalities and merger of solutions due to company amalgamations are becoming ever more predominant in our changing environment.

Your advantage

A systematic process, requirements engineering proficiency and appropriate software tools to manage requirements help to define tasks and goals clearly from the beginning. Changes are communicated continuously and documented seamlessly. This is essential for working together efficiently and thus successfully in a project team.

Skillfully automated requirments engineering will repay you in time-to-market, quality, reuse of key know-how and keeping a handle on cost. And you can monitor the development projects to meet your customers’ needs.

Basis for step-by-step development

In today’s market pace, it is impossible to define a new product in advance completely before the start of a project. This is partly because an understanding of the requirements comes with time, especially in innovation driven developments. In addition, customers change their minds and applied technologies undergo further development, enabling new insights and solutions. Therefore it is im-portant to begin development as quickly as possible and integrate new requirements along the way. Regular feedback loops ensure that the path you pursue is the right one.

A few basic principles to be followed

Each company has its specific “requirements information model”, including process, workflows and specific access rights. This needs to be documented as a baseline.

Teams must work on a specific development step during different phases of the project and must ensure that it always meets current requirements.

All changes must be analysed in terms of impact before being implemented.

All affected team members must be notified immediately upon changes in requirements, to allow them to respond appropriately and not work on “out-dated” requirements.

Investment in requirements engineering - high ROI

Studies show that skills in requirments engineering are still very low which may be corre-lated to the investments in Training. Skills in requiremens engineering seem to be taken for granted by management. As such it is no surprise that RE can be associated to many failures. Additionally investment in tool support is also low – again surprisingly as for an efficient development an effective RE solution is essential.
