This is the stage of the
systems analysis cycle where all the work so far is finally pulled into one
cohesive blueprint. Often a report is created summarising and listing
documents and findings from the previous stages.
This will act as a “target” for the systems design to focus in on.
What is created is not an image
or map of the final product but a highly detailed plan.
This purposeful and deliberate arrangement of known details and
requirements into a solution that fully expresses the investigative work of the
preceding stages results in a clear step-by-step guide for the creation of the
final product.
If each of the preceding phases
have been completed to the highest levels of skill then this stage is likely to
be virtually self-completing. All
questions of need, layout, look and feel, access rights, training, systems
requirements, speed and every other detail down to the level of choice of one
word over another should have been answered by the in depth investigations.
Here charts are created and
every aspect of the new system is fully codified.
For the first time an over view is available of the system at a depth
deeper than the feasibility study report results. Now the how is dealt with.
This stage deals only with preparation for the implementation stage.
Consideration of the following points is vital:
- Time scale and time management systems
- Who will be doing which part of the implementation?
- Which users will be using what?
- Which members of the analysis team will require
access to the various notes – duplicates may be required to be stored in a
common location.
Once the requirements of this
stage have been met, namely the codification of the final product or solution,
then work can proceed on the next stage: Implementation.
