EXAMINING ALTERNATIVE SOLUTIONS

HOSTEL INFORMATION SYSTEM

ALTERNATIVE SOLUTIONS

A: Improve manual system

B: Use PC based periodic update system

C: An on-line system with server and several clients

SOLUTION A: MANUAL SYSTEM

Keep up-to-date running total of extras and rebates for each student, use look up table to find material needed each day based on number of extras, calculate standard quantities needed and use for vendor order, track student payments to find overdue payments. Solution does not ensure reduction in bill variations and prompt payment to vendors, solution not scalable to large student population

SOLUTION B: USE PC BASED PERIODIC UPDATE SYSTEM

Use a single PC to prepare students bills and to itemize bills, prepare a list of number of members who will eat for next two days, alert warden when bill is not paid within 10 days of issue. Use a PC to generate Vendor order, Inventory control of store and Menu planning.

The PC configuration needed based on data base sizes is:

PC with 20 MB disk, 1.2 MB floppy is sufficient. However minimum configuration available today(2004) is PC with 128 MB main memory, 40

GB disk 1.2MB floppy & CD R/W costs Rs. 25,000.Systems software (Windows XP, MSOffice, anti-virus) will cost around Rs.25,000.

So, the Total cost is Rs 50,000.

But a PC with printer and uninterrupted power supply costs Rs. 70,000

SOLUTION C: AN ON-LINE SYSTEM WITH SERVER AND SEVERAL CLIENTS

Use a server which is accessed by 3 clients one each in the mess, the stores and the accounts sections; perform on-line transaction processing. The advantage is up to the minute status can be found

EVALUATING ALTERNATIVE SOLUTIONS

Determine Technical feasibility of each solution, in other words is technology mature to implement a solution. Determine Operational feasibility of each solution. In other words, for a given organizational structure will the solution fit in. Will it provide right information at the right time to users? Determine Economic feasibility of each solution. In other words, are finances available to implement system? Will it be cost effective? Will the money spent be recovered by savings or by better services to users.

TECHNICAL AND OPERATIONAL FEASIBILITY

Solution B is rejected, as it does not meet most of the requirements. Solution C is rejected, as it is a high cost solution.

Solution B is selected for further consideration. It is technically feasible as PC of necessary configuration is easily available. It is also operationally feasible as clerks in hostel office can be easily trained to use a PC.

System analyst/ programmer hired for this purpose will write the necessary problems.

Why do we need information systems, management structure, requirements of information at different levels of management NEED FOR INFORMATION SYSTEMS Information systems are needed when timely processing for fast action is needed, same data has to be processed in different ways and when organizations require innovative processing. MANAGEMENT STRUCTURE Functional areas of management are as follows: •PRODUCTION • MARKETING • MATERIALS – purchase, stores • FINANCE –Accounts • HUMAN RESOURCE DEVELOPMENT(HRD) • RESEARCH AND DEVELOPMENT (R&D) INFORMATION FOR MANAGEMENT A Production Management The following type of information is needed in production management: Strategic Information: 1)Yearly and monthly production quotas and alternate schedules 2)Policies on machine replacement, augmentation and modernization. 3)Identifying best product mix. Tactical Information 1)Identifying and controlling areas of high cost. 2) Identifying critical bottlenecks in production. 3)

The User Interface:Establishing User Interfaces

The User Interface Establishing User Interfaces The success factors in analysis start with the established interfaces from day one. What does this mean? You must start the process by meeting with the right people in the organization. In the best projects, the process is as follows: 1. Executive interface: There needs to be an executive-level supporter of the project. Without such a supporter, you risk not being able to keep the project on schedule. Most important, you need a supporter for the political issues that you may need to handle during the project (discussed in detail later). The executive supporter, sometimes known as a sponsor (JAD reference), should provide a preliminary schedule advising the organization of what is expected and the objectives of the project. The executive supporter should attach a letter to the preliminary schedule and send it to the project team members. The letter must put the importance of the project into perspective. Therefore, it is strongly rec
