Chaudhary Group of Industries wants to build a computerized sales forecasting system for Wai Wai Noodle. The objective of the system is to forecast the sales for the coming year 2010.
a) Which model of system analysis and design will you propose and why?
b) What are other systems which have correlation with sales forecasting system? How are they correlated?
c) Make a sample output report format for the sales forecast.
The main objective of this type of question is to check the student‘s analytical ideas and problem solving techniques. So there might be various types‘ concepts and design can be expected from students. However for the evaluation following points should be taken into consideration.
Any one method of system development life cycle with relevant figure like Water fall model or Spiral model can be accepted. But students should clearly specify which method is being used and the reason of using that particular development process. During each steps of development process the task carried out should be clearly be specified. E.g Here spiral model of system development is proposed.
The spiral model is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. Also known as the spiral lifecycle model (or spiral development), it is a systems development method (SDM) used in information technology (IT). This model of development combines the features of the prototyping model and the waterfall model. This involves the continuous process of system development. As it combines the prototype and water fall model most of the activity would be covered.
a) Other system which are interconnected with the Sales Forecasting for the Wai Wai noodles are as follows:
i) Human Resource Information System.
ii) Accounting and Finance Information System
iii) Procurement and Production Information System
iv) Marketing Information System.
Human Resource Information System:
HRIS is mainly concern about the recruitment, training, promotion and record keeping of the office personnel. Personnel effort is one of the major factors for the growth of next year sales. Reverse perspective, if next year sales increases highly obviously the workers are eligible for the incentive according to their effort.
Accounting and Finance Information System:
This is responsible for keeping the record of all monetary transaction related with procurement, salary, marketing etc. Moreover financial information system helps to analyze the investment, profit and loss related with the sales for the year 2008.
Procurement and Production Information System:
Procurement Information System provides the information regarding the purchase of the raw materials to meet the required target of sales. They also give the information regarding the delivery of the materials purchased. Where as production information system supply the information related with the machinery, fuels, workers scheduling etc.
Marketing Information System:
It provides the information related with the product promotion ideas, identification of new customer to meet the required target of the sales.
