What Control Systems do you need

If you answer the following questions and email to us we will provide a free and confidential review of your manufacturing and supply chain control system needs using our expert systems. It will also indicate where you are not world class, indicating a development need.

Because the underpinning research for these expert systems was funded by the UK Government, this service is available free to UK manufacturing businesses only. It is not available to consultants.

Guide to answering

Answer: "Yes" or "no" only. If in doubt describe your dilemma to us.
If you do not know the answer this will limit our ability to advise you fully but our response may still provide you with useful information? In this case it is acceptable to estimate to the extent that you perceive the issue to be significant to your business or not. But you should be aware that these measures have been derived from best practice models so even if you do not perceive things to be a problem you may be significantly worse than World Class (or your competitors).
It is possible in some businesses that two answers may be necessary for different parts of the business. In this case fill in two questionnaires and identify the different areas, so that we can advise you separately for each.
It is possible to answer the questionnaire in the past, present, or future tense. For example if you have unreliable suppliers today, but will solve the problem shortly, answer in the future tense and we will assume it is not an issue to be considered.
The questionnaire is split into 4 sections and can be copied and preferably pasted into an "HTML", or "rich text", email for return. If pasting into a "plain text", email, formatting will be lost but is still acceptable. (Please do not send as an email attachment):
