The duration and event times include earliest times and latest times were used to find out the critical path. Depend on the critical path and the float time, the Gantt chart is produced in order to control every activity in the project. Finally, the investment appraisal techniques that Co-op Supermarket uses will be considered. The company has to choose the most effective project within three projects A, B and C to invest.

Therefore, it has to use financial tools to assess and evaluate them. The Net Present Value (NPV) and Internal Rate of Return (IRR) and other financial tools such as Modified IRR (MIRR) and the benefit-cost ratio B/C are used to calculate different values of three projects. First, top lever or executive level of management includes the most important people who can decide the development of the whole organization such as the Chief Executive Officer (CEO). The Executive Support Systems (ESS) is the tool which can help these senior managers to make strategic unstructured decisions.

An ESS can provide senior managers with easy access to key internal and external information of the company. This also helps them to come up with long team planning. Therefore, the information that the manager of Co-op Supermarket may need for the strategic level are the forecasts of 5 year sales trend, 5 year operating plan, 5 year budgeting plan, financial plan and human resources plan. For example, in order to come up with a decision of making a financial plan, the manager needs to combine both internal and external information.

The internal information would be the financial data of the company over the last few years from the office systems and analysis. The external information would be the development of Vietnamese economy, the competitors’ development and also the make share with trends of prices. ESS has many different features that helpful for management to make decision. It is flexible since the information can be taken from official or unofficial sources. It is suitable for quick response time since it relies on graphic presentation of information, not detailed information.

So the manager can take the general information easily and the process of making decision can be shortening very much. 1. Middle/management level Middle or management level has two information systems which are Management Support System (MSS) and Decision Support System (DSS). DSS can be used to support the manager in semi-structured or unstructured decision making. They are intended to provide a wide range of typical information that a decision support application might gather and present. Using these systems, the middle managers will be able to control the business and ensure that the system is in a good condition.

Management Support System (MSS) provides the vision people need to maximize control over the operations (Majure, n. d). It gives the management a chance to have the real-time feedback on the operations so they can make quick and informed decisions. Therefore, the information needed at tactical level or middle/management lever may be the sales management, sales region analysis, inventory control, production scheduling, annual budgeting, cost analysis, capital investment analysis, pricing/profit ability analysis, relocation analysis and contract cost analysis.

For example, when the manager of Co-op Supermarket want to add more types of product to sell in the supermarket, they can use DSS to find out the customer’s need and wants, their requirement, interesting, hobbies, and incomes. This information would help the manager to get the general knowledge about the current position and the market to balance the benefit they can get with the risks that they have to take to control and develop the business. 1. Lower/supervisory level The lower or supervisor level is not as important as two other levels. It is used daily and with short team decision.

There are three information systems included in this level which are Knowledge Work Systems (KWS), Office Automation Systems (OAS), and Transaction Processing Systems (TPS). Knowledge Work Systems (KWS) are information systems that facilitate the creation and integration of new knowledge into an organization (BPP Professional Education, 2004, p276). This system take part in motivate knowledge worker to improve themselves with different skills such as Computer Aided design (CAD), Computer Aided Manufacturing (CAM) and Specialized financial software that analyses trading situations.

For example, with this method, a servicing staff can create a new way to arrange the product to attract more customers according to the interests and excitement of customers and other strategies of the company’s competitors. Office Automation Systems (OAS) is computer systems designed to increase the productivity of data and information workers. The major activities of typical office such as document management, facilitating communication and managing data can be supported by this system. For example, in order to develop the customer care services, Co-op Supermarket’s manager can use this system to provide e-mail.

This e-mail can be send to different customers to make them satisfied and also remind them about the company image. In the process of using this method, Co-op Supermarket has to consider both internal and external information. Such as information about the company’s service, activities, etc for internal and customer’s needs and wants, also general market information for external. Transaction Processing Systems (TPS) perform ad records routine transactions which are necessary to conduct the business.

For example, Co-op Supermarket want to create a payroll for employees, the manager can use TPS to do this work easily since the system provide the information about the employees’ performance, labor position, and other related information.

Finally, the Office Automation Systems (OAS) can be applied in order to attract and satisfy more customers.

Many different strategies which use this system need to be provided daily such as advertisement, e-mail, letter, leaflets, etc 1. Manufacturing department: Because managers have to control the amount of product everyday to conclude the productivity that means the inventory of the company must be control. Moreover, the machines of the Co-op Supermarket also need to monitor, so the Decision Support System (DSS) can be applied to make it easy to manager to control the manufacture of the company. 1.
