1 Scope
This Handbook provides advice, interpretations, elaborations and software engineering
best practices for the implementation of the requirements specified in ECSS‑E‑ST‑40C. The handbook is intended to be applicable to both flight and ground. It has been
produced to complement the ECSS‑E‑ST‑40C Standard, in the area where space project experience has reported issues related
to the applicability, the interpretation or the feasibility of the Standard. It should
be read to clarify the spirit of the Standard, the intention of the authors or the
industrial best practices when applying the Standard to a space project.
The Handbook is not a software engineering book addressing the technical description
and respective merits of software engineering methods and tools.
ECSS‑E‑HB‑40A
covers, in particular, the following:
a. In section 4.1, the description of the context in which the software engineering standard operates,
together with the explanation of the importance of following standards to get proper
engineering.
b. In section 4.2, elaboration on key concepts that are essential to get compliance with the Standard,
such as the roles, the software characteristics, the criticality, the tailoring and
