This is a case study of Decision Support System called ACRPLAN which Bayer Cooperation installed to assists it with financial planning and budgeting. Some of the problems that the company was encountering during budgeting planning are slow budgeting process, difficulties in obtaining financial data to use in budgeting.
This was a problem because all the company’s data were stored in various computers and obtaining them in all the company’s department was quite difficult. There was also inefficient in communication methods between the different departments of the company.
There was no single person who could understand the whole company’s data from all the departments and present it to the budgeting personnel to assist with budgeting purposes. The company was also faced with another problem of generating several budgets hence creating redundant data during budget generation. These most of the redundant data occupied the company’s resources and were never used.
The management of the company was also faced with another problem of lack of sufficient data for decision making. The budgeting process was tedious and time consuming so the managers had to wait for all the company’s data to be gathered and the budget be drawn.
The company was previously using excel worksheets which required manual input of data and this process increased the company’s budgeting costs since it had to hire data entry clerks to enter data to the excel worksheets. The excel worksheet was sophisticated and required a lot of training.
The company was growing at a very high rate and this was creating problems to the budgeting team because they could not accommodate all the requirements of the extraordinary growth of the company. The other problem was integrating the company’s business processes and the planning process which were increasingly becoming complicated (Gachet, 2004).
The volume of data that the company was generating was also high and analyzing this data for financial planning purposes was quite difficult. Most of the company’s personnel were doctors, sales people, and research scientist who had little knowledge of financial planning and budgeting.
This created problems because the company’s financial data was quite complex and the company had to hire a financial expert to analyze the data and generate the company’s budget.
