Hmmm well I generally use the terms as:
Specification: What has to be done.
Analysis: How you are going to do it.
I use 'design' as a term referring to the actual high/low level designs,
including any DFDs/etc. I believe that the design plays an important role,
while the analysis isn't so important for a mud if you are the sole coder.
I know what I want to do, I know how I am going to do it. What I need is a
consistant design to stop me deviating from that goal.

I think the main difference is that you consider the players to be the
customer, while I consider myself to be the customer (of my mud). If
the players were customers then yes, I would agree with you totally.

[snip rest of explaination]
Specification of problem:
The mud cannot accept more than 100 players at one time.
Analysis of problem:
Within the following header file:
Socket.h
The following literal:
#define MAX_PLAYERS 100
Shall be modified to the following:
#define MAX_PLAYERS 200
This shall allow upto 200 players to be connected at one time. The
object design specification shall also be updated to reflect this change.
Requirements tracability impact:
Within the following section:
1.1.3 Player limitations
The number '100' shall be replaced with the number '200'. The tracability
matrix shall be updated to reflect this change.
Verification method:
Changes to the high level design shall be verified by scrutiny against the
requirements document, the design document, the codes of practice for
verification and the tracability matrix.
Changes to the code shall be verified by scrutiny against the module
specification, the requirements document, the design document, the codes
of practice for C coding and by independant module testing of the affected
item.
Maybe we are getting our wires crossed...could you give a brief example of
what you consider 'analysis', 'specification' and 'design'?

True, but I have never doubted the importance of design.
