Design of interoperable complex systems

Most of our projects focus on the design of complex systems. They require the interoperability of many components and industrial subsystems from mechanical, electronic, automatic and computer engineering: mechatronics. We also speak more generically of integration or system engineering.
In addition to the unitary development of each of the components, the difficulty of this type of project lies in the complexity of the overall design, in the definition of interfaces and means of interoperability between subsystems, as well as in the care and completeness. "Testing" that will validate the proper functioning of the complete system.
This is where our first expertise lies: to be able, following an analysis of your needs, to design an overall solution, integrating components and subsystems of our different expertise.

Project management
"There is no favorable wind for those who do not know where he is going" ( Seneca )

A SAPHIR Project Manager is accountable to the Client for all the commitments related to a Project over its entire lifetime, from pre-projects to maintenance. He coordinates all the stakeholders involved in the project: technical team members, management, logistic actors, suppliers, subcontractors.

Modes of commitment

We operate the majority of our projects in an obligation of results, by engaging ourselves on a perimeter, a delay and a price.

Alternative modes of engagement may be proposed, including:

  • Lump-Sum, a design-to-cost approach (optimization of value for a given budget)
  • Controlled Expenditure Plan: Time-Based Billing Driven by a Customer Driven Resource Engagement Process and Method Commitments
  • Simple commitment of means: billing time spent. Particularly adapted to the phases of early stages, or for one-shot technical assistance
The role of Project Manager (MOE)

We are usually project managers of the projects we are working on, which implies taking responsibility for the design of the solution, the management of the works and their control. This implies a coordination work of all the actors and suppliers likely to intervene.

We may also be a Supplier of a lot, or a given component, as part of a larger project, followed by a third party project manager. And it may happen that our Clients assume this role of Project Manager.

Methods
"What is well conceived is clearly stated, and the words to say it arrives easily. »( N. Boileau )
The Requirement Management Method

We generally use the Requirements Management method, which is particularly suited to the realization of Complex Systems. This method "hatches" the entire Project and its deliverables, for example the General Specifications (then Detailed) and the Test Plans. It involves the establishment of a Traceability of Requirements that ensures compliance between the expressed need and the solution provided.

Process: Cycle in V or Agile

Most of our projects have a perimeter clearly defined by our customers, unlikely to be changed during the project. Then, we generally implement a "V cycle", punctuated by milestones (or journals) validating the progress of each step.

Alternatively, we propose using an Agile process (Scrum) for projects with objectives, priorities or perimeters which must be able to evolve during the realization.

Documentation

We provide on each of our projects a documentation "at the state of the art", relating to the phases of design, test, manufacture, use or maintenance for example. And we are also used to particularly high levels of requirements, typical of the sectors for which we work, notably Aeronautics, Space, Defense or Nuclear.

 
Testing

The test aspects are critical, essential. On some projects, the cumulative work of Test can also represent the bulk of the Project load, particularly for Sensitive Systems. Testing covers several aspects:

  • The ability to ensure the traceability of requirements throughout the tests
  • The development of a Test Strategy and the writing of Test Plans, from the Project Specification phase
  • Effective and optimal management of test covers
  • Taking into account the functional and technical specifications (functions, performance, endurance in particular)
  • Anticipation of the specific technical means to be implemented (eg simulators, injectors, test sets)
  • The realization of "unit tests" for each component
  • Performing "2 to 2 tests", "interface tests" and integration tests
  • Performing functional validation tests
  • And of course, the completion of the acceptance tests, which validate the compliance of the System to the Recipe Milestone.

We have the means to be efficient and productive on these aspects: Test and Validation process under our Quality Management System, tooled platform dedicated to integration and testing, continuous integration tool, tool for monitoring requirements in particular.
