Hi Everyone,
I'm experiencing a bit of a challenging obstacle within my project. Just a bit of background, the project entails defining standards for the Group ICT of a mining outfit.
The one I'm working on at the moment is standards for access control.
The challenge experienced with regards to this is in developing a model that takes into account the number of individuals going through a random access point and determining the fit for purpose access control mechanism/instrument to implement.
What sort of variables would one typically consider in constructing such a model?
I'm sorry, but I don't understand what you are trying to model. What is Group ICT? What do you mean by "random access point"? Can you provide more details for those of us that aren't familiar with the mining industry.
Hi cadams,
My apologies for being so unclear. To answer your question Group ICT is actually Group Information and Communication Technology and by random access point I was referring to any implemented mechanism that allows for persons or vehicles to gain access to the mine's permeters, e.g. turnstiles, boom gate, etc.
The result I'd like to reach is being able to punch up a few numbers (as per the variables) thereby allowing me to make an informed decision of which access control mechanism to suggest for implementation.
I hope I was a bit clearer on this one.
Hi,
If I understand you correctly you want to select something to controll access to mines.
To select the right something you need to select the best one - to define the best one is where business analysis comes in: define what are going to measure that will allow you to assess after implementation whether you selected the right one or not. Then define the target value that (if attained) means it was successful. Example: we will measure the number of access points it can handle and if it can handle at least 25 it will be deemed successful. There will be about 6 to 12 of these objectives as business analysts call them. Get these signed off by anyone who is authorised to stop your project and is involved in some way with it.
Now define what you need this thing to do in order to achieve the objectives. Example: the mechanism needs to allow new access points to be created. So long as you can prove that you need this functional requirement in order to hit the objective, that's fine. Get these signed off by anyone who is authorised to stop your project and is involved in some way with it.
Finally define what you need non-functionally - who can use these mechanisms, where (geographically), what times of day, what days of the year, what security access controls are required, what performance rates are expected and so on.
Now you can go to vendors and say "show me how you support all this functionality". Rate them for each function, and those that score highest progress with.
There's a lot more to this selection process but it would be good to know if I am answering the question you are asking first!

Hi Guy,
You have certainly guided me to a point I wanted to be at.
The what(s) - Access Type Required and No. of Access Points
In order to determine this, the following variables will need to be considered:
Zones - Main Entrance; Gatehouse Building; Change Room; Lamp Room; Offices; Lab Who - Employees; Visitors; Vehicles; Paraplegic Daily Estimate - any number
Example:
So, if entry is at the Main Entrance and access if for employees - how many access points do we need and what type of access device will allow for the most effecient throughtput?
The requirement: Put all this into a model.
I suppose another good question to ask is, what exactly is a model?
