Case Study
MR Ltd. Manufactures industrial glues and solvents in a ingle large factory. Approximately 400 different inputs are used to produce 35 specialist outputs, which range from ultra-strong glue used in aircraft manufacture to high impact adhesives that are required on construction sites.
Two years ago, with the company only just breaking even, the directors recognized the need for more information to control the business. To assist them with their strategic control of the business, they decided to establish an MIS. This is now operational but provides only the following limited range of information to the directors via their networked computer system.
1. A summary business plan for this and the next two years. The plan includes details of expected future incomes and expenditures on existing product lines. It was produced by a new member of the accounting department without reference to past production data.
2. Stock balances on individual items of raw materials, finished goods etc. This report is at a very detailed level and comprises 80% of the output from the MIS itself
3. A summary of changes in total demand for glues and solvents in the market place for the last five years. This information is presented as a numerical summary in six different sections. Each selection takes up one computer screen so only one section can be viewed at a time.
Read the above case and answer the following questions:
1. (i) Comment on the weaknesses in the information currently being provided to the directors of the company
(ii) Suggest how the information may be improved, with particular reference to other outputs, which the MIS might usefully provide to the directors.
