Random Search Selection is a simple security procedure that is well established across a wide range of industries such as loss prevention, alcohol & drugs testing in fact anywhere, where a totally random call needs to be made. It’s a random process of selecting people from a group in a totally random and unpredictable.
There are many of ways to implement this procedure such as software selecting from a list of employees, but this is flawed as it has little or no visible deterrent & could be argued that the software is manipulated in some way. You could randomly select people for search however by the very nature of using people to do the task, it cannot be truly random, 'people' are not inclined to be random, we think before we act, therefore any individual selected (or allowed to pass!) has been done so for a reason - that is not random & therefore biased or open to corruption with the associated discrimination implications. Then of course you could have a large bag of balls marked search or pass, not exactly portraying the cutting edge professional image you would expect in this day & age.
Random Search Selectors are truly random, unbiased and incorruptible, always 'awake' and functioning, and importantly provide the high profile deterrent that makes Random Search Selection such an efficient and cost effective method of company policy enforcement. Typically you would only need to set 5% alarm rate in an established secure establishment; this ratio can be adjusted by yourself very simply should you need to.
