MTJB Engineering was to provide requirements development and management for a new Line Replaceable Unit (LRU) to be fitted to Boeing aircraft.


MTJB developed the following requirements documentation feeding in to the wider programme:

  • Top Level Specification
  • Unit Requirements Specification
  • Analogue and Digital Control Interface

The process involved multiple stakeholder management across safety, Software, Hardware and testing to develop the requirements at all levels.

Part of MTJB’s responsibility was the raising of documentation to highlight errors and taking them through the various governance boards ending in incorporation to the current documents to allow uplifts. This involved providing the evidence and compliance matrix to demonstrate the rationale behind each change..
