I am currently working on a Capacity Planning project for my office,
and i'm interested to hear your thoughts on the best way to approach
something. here's the scenario;
The database is used to record individual workpackets, start dates,
users id's etc. Each work packet is classified by a complexity value,
1-5. These complexities are assigned a point value by the system to
allow us to conduct performance monitoring and planning. The points
equate to hours, so that any anyone time we know roughly how many hours
work we have in. The point value is constant per complexity, as per the
table below.
Complexity Points
1 1
2 3
3 12
4 36
5 72
From experience we know roughly how many of each complexity we will be
receiving in a month, and so how many points we get in.
Now, heres the situation. We are expecting an uplift in work load,
about 30-40 rise. We therefore need to predict the total ammount of
points that we will be receiving, and therefore how many more staff we
will need. Simple as that? Not quite! We are not sure whether the
increase in work load will be to the same ratios we have at the moment.
S for example, we need to understand what an increase in the numbers
of complexity 5's would mean to us. Equally, what would happen if
there was a large amounts of complexity 1 projects coming in, and a
rise in the numbers of 3's. Another idea is that the complexity 5's
might increase, but the 1's decrease as well, so the total number of
jobs we receive stay the same, but the points change significantly.
To try and help with this, I have set up a form, that has the number of
each job type received in the last year, the % of total amount, and
their point values. I have then set up 5 sliders, one for each
complexity, that are preset to the % ratio. What I want to do is be
able to drag a slider bar to simulate an increase in that work stream.
I can do this part quite well, i can get the form to msgbox me with the
new points total. This however is increasing the number of jobs. Any
suggestions on how I could get the system to adjust the other sliders
down when I increase one of the other sliders? I thought about just
displaying the total % and getting the user to balance the other
sliders until we hit 100%, but it would be great if they could lock
some of the bars, and the others adjust automatically.
i realise this is a long post, so i appreciate you reading it. i'd
appreciate it even more if you could help me out with your ideas. I
can probably do this, but I want to see others views, or whether anyone
else has done anything similar.
