Systems Engineering can be described as an interdisciplinary process that ensures that the customer's needs are satisfied throughout a complex system's entire life cycle. Systems engineering deals with work-processes and tools to handle such projects, and it overlaps with both technical and human-centered disciplines such as control engineering, industrial engineering, organizational studies, and project management.


This interdisciplinary process can be comprised of the following tasks:

  • State the problem. Stating the problem is the most important systems engineering task. It entails identifying stakeholders, understanding its needs, establishing the need for changes, eliciting requirements; and finally defining system functionalities, regulatory needs, concepts of operation, and its verification and validation.

  • Investigate alternatives. Alternatives are investigated and evaluated based on technology availability, performance, cost, schedule and risk.

  • Model the system. Running models clarifies requirements, reveals bottlenecks and fragmented activities, reduces cost and exposes duplication of efforts.

  • Integrate. Integration means designing interfaces and bringing system elements together so they work as a whole. This requires extensive communication and coordination.

  • Launch the system. Launching the system means running the system and producing outputs -- making the system do what it was intended to do.

  • Assess performance. Performance is assessed using evaluation criteria, technical performance measures and measures -- measurement is the key. If you cannot measure it, you cannot control it. If you cannot control it, you cannot improve it.

  • Re-evaluation. Re-evaluation should be a continual and iterative process with many parallel loops.

Renaissance Consulting extensive experience in aeronautic, space, security and defence projects (specially research, safety-critical, unmanned and control ones) is a guarantee to provide you technical support in complex projects.


Renaissance Consulting has developed a USAR-based (i.e. STANAG 4671) methodology SysEngUAS and a series of aids to apply System Engineering to UAS for a fixed-wing UAV with a MTOW between 150 and 20000 Kg. A similar approach will be developed for a fixed-wing Light UAV (i.e. SysEngLUAS) and a rotary-wing UAV (i.e. SysEngRUAS) as soon as their technical airworthiness requirements (i.e. STANAG 4703 and STANAG 4702 respectively) are authorised:
  • SysEngUAS is a methodology based on USAR structure to apply the Systems Engineering principles to develop very complex systems such as UAS. This methodology is also extremely valuable when dealing with the certification aspects of the development and is used as a preliminary approach to the regulatory bodies.

  • Technology Watch is a continuous process review of UAS-related technology. Renaissance Consulting is part of different Research, Electronics, IT and UAS organizations and associations; being subscribed to many sources of UAS-technology news world-wide. This allow us to keep track of new developments regularly.

  • Regulatory Observer is a continuous process review of UAS-related regulatory aspects. Renaissance Consulting is an active member of EUROCAE WG 73 (we coordinated the SG4 response to JARUS proposed regulation for UAS flight crew licensing), the EC-industry LUAS Group, the UAS community worldwide and is knowledgeable to the Spanish UAS civil and military regulatory authorities. This allow us to keep up-to-date in the regulatory matters.
