Verifiable and Unambiguous System and
Sub-system definition
Our approach to system analysis allows us to define systems
and sub-systems unambiguously and verifiably without any implementation
bias.
We start from a key principle of treating the system as a
single 'black box' and use techniques from UML to develop
a system functional specification. This is followed by architectural
design and subsystem specification. We again use UML techniques
to support our approach. We use only a subset of the selected
notations in order to keep the level of abstraction appropriate
to the early stages of the lifecycle.
The major applications of our methods have been to systems
for the rail industry, where a rigorous approach is demanded
by the safety-related nature of the applications. The systems
presented different problems, and had substantially different
architectures, but the same methods were effective in each
case.
We have found that using modelling techniques to express a
system design provides a systematic and rigorous approach
often lacking in high-level design documents.
Benefits of using Praxis System Analysis and Design: a structured
framework adaptable to a project's needs.
| Benefit |
Achieved through |
| Reduced System Integration time and costs |
Requirements led, top-down design methodology |
| Reduced Sub-system development time and
costs |
Use of abstraction and object orientated
modelling techniques to manage complexity and sub-system
variants |
| Reduced risk |
Iterative assessment against defined set
of design targets |
| Separation of concerns |
Distinct architectural views chosen to support
the specific design considerations of the system (e.g.
human factors) |
| Cost effective system integrity and quality |
Appropriate use of formality and structured
recording of design decisions |
