[Year 12 Its] pilot is semiparallele

[Maggie Iaquinto]

In the reading I have done, given some prompts from mail to this List
(Frank perhaps?), I have learned that pilot is an implementation
strategy not done on its own. Rather, pilot is now considered a
semiparallel form of implementation. Data is entered into an old system
AND a new system at the same time with pilot.

 So-- if pilot is used, then pilot + direct is OK  OR  pilot + phased is
OK.

On the IPM exam, I reckoned the examiners were looking for 'pilot' but
with the phrasing of the question, there were two correct answers :
pilot and parallel.

 Thanks Mark and Kevork for making this exam more easily understood.
The only thing I might add to this discussion is for the implementation
strategy mentioned in Section B Qn 13.
It would seem from the question that the desired answer is "pilot".
However, when you think about it IMHO a pilot is not an "implementation
strategy" as after it is tested it still needs to be implemented - and
if it is used in a small section of a network and then expanded
throughout - then it is indistinguishable from "phased implementation".
(I might be shaking the foundations here a little.)
If a pilot was trialled outside of the system - as a much smaller system
- it could still be implemented in the real world using a "direct
cutover" - or in theory, it could be applied in parallel across the
system - hence it could be "parallel" conversion. Or it can be expanded
from use in a part of the system - "phased".
There is nothing in utilising a pilot that determines 'implementation',
I feel.
So IMO the answer in this case should probably be either "pilot" or
"phased" depending on student descriptions.
