Systems engineering and assurance

Our leading expertise encompasses every element of systems engineering to ensure delivered systems meet their aims. Technical excellence enables our engineers to design and develop integrated systems which exceed the expectations of clients, while providing assurance that the full scope of the project has been implemented.

Increasing complexity in large-scale projects is fuelled by the need to build and integrate sophisticated products, which deliver enhanced performance and which have the flexibility to adapt to users' future needs. As specialists, we have the multidisciplinary expertise needed to apply systems engineering and assurance effectively throughout the life of infrastructure and technology projects.

From inception to operation our requirements management solutions, systems integration and technical assurance services make decision making explicit and justifiable. Some of our key services include:

  • Requirements management
  • Verification and validation
  • Interface management
  • Configuration management
  • System integration
  • Technical auditing
  • System assurance

Systems engineering

We use a structured knowledge-acquisition process to elicit and document functional, non-functional and interface needs. This enables us to facilitate the specification of unique, traceable and unambiguous requirements in a concise and consistent format.

We select the appropriate requirements management tool to help save time and minimise cost and risks. We've have used tools such as DOORS for example.

We also ensure verification and validation against all process and system requirements. By linking these with functionality and performance testing, our team is able to provide quantifiable assurance that a system fully complies with its design and yields operational efficiency and reliability.

Careful integration on multidisciplinary projects is vital to cost-effective completion. To this end, our system engineers use the most appropriate tools and techniques. This includes architecture modelling, which covers system decomposition as well as providing descriptions of sub-system functionality and operational behaviour.

We also provide related services such as reliability, availability, maintainability and safety, human factors (ergonomics) and electromagnetic compatibility, to help identify and define integration issues which need to be managed to completion.

Dealing with the fragmented nature of service delivery in some programmes introduces multiple stakeholders and complexities. Our global presence and diverse partnerships across the industry means we have a strong track record of identifying and defining functionality at technical, operational and commercial interfaces.


We are highly skilled in delivering progressive system assurance services to complement our systems engineering activities. We maintain the right amount of independence from delivery, to optimise the balance between time, cost and quality.

Through systems assurance activities we provide a service which demonstrates to clients whether a project or product in question is being developed and delivered effectively in line with all relevant standards and processes.

Systems assurance provides the client with confidence, reduces risk, and helps ensure that a completed project meets all project stakeholders’ requirements.


Driven by customer needs, we focus on supplying innovative and pragmatic solutions to a number of sectors, including:

  • Buildings
  • Industry
  • Oil and gas
  • Power
  • Technology and communications
  • Transport
  • Water

Our systems engineering consultants are members of key professional bodies; Institution of Engineering and Technology (IET), Institution of Mechanical Engineers (IMechE) and International Council on Systems Engineering (INCOSE).

They have the experience and expertise to orchestrate complex ideas effectively and implement practical systems tailored to projects of any scale.

Our team combines systems engineering tools and processes with people and technology to create structured design and delivery processes that provide sustainable solutions, ensuring overall capabilities satisfy client needs.
