Company History

Pizza Hut began operation as a single pizza shop run by two brothers, Dan and Frank Carney, in Wichita, Kansas on June 15, 1958. The chain grew to 43 restaurants in 1963 and 296 in 1968. Pizza Hut went public in 1969 and was acquired by PepsiCo, Inc. in 1977. By 1981 Pizza Hut had become the largest pizza restaurant chain in the world both in sales and number of restaurants.

Pizza Hut franchisees exemplify the entrepreneurial spirit which launched its system back in 1958. Through interest and initiative, the Pizza Hut system was able to develop new territories both in the United States and overseas. Today, franchisees and joint venture partnerships account for more than half of the Pizza Hut system's total units. The development on the international front is a good indication of the growth that has characterized our system. Following the opening of the first international restaurant in Canada in 1968, Pizza Hut restaurants quickly appeared in Mexico, South America, Australia, Europe, the Far East and Africa. Today, Pizza Hut operates in 84 countries and territories throughout the world.

OVERVIEW OF THE CURRENT SYSTEM

MODEL OF THE EXISITING SALES SYSTEM

ANALYSIS OF THE CURRENT SYSTEM (BRIEF)

INFORMATION PROBLEMS, OPPORTUNITIES AND CAUSES – EFFECT ANALYSIS

Currently the Pizza Hut ordering system is automated. Even though all the orders are manually maintained to later be managed into the system. Often results in the waste age of time and money. Dues to this, it is quite intricate to ensure the facts of the order simultaneously. Employees have to go through the same steps repeatedly.

ECONOMIC PROBLEMS, OPPORTUNITIES AND CAUSE - EFFECT ANALYSIS

In the beginning, the need for a sophisticated (yet simple) automated system wasn’t a core issue. The simple office based application was full filling the organization’s needs.

The continuous triumph of MCR Pizza Hut has brought a need for such an automated system that will maximize the potential of the user, and organization saving time and money.

The current sales Management system serves its purpose but not to its optimum potential. Analysis of sales data is difficult, creating personalized reports; even day-to-day report becomes tedious without a completely integrated back office system.

DETAILED RECOMMENDATIONS

SYSTEM IMPROVEMENT OBJECTIVES:

The current sales management system, which is being used by Pizza Hut, isn’t helpful enough in this period of tough competition; it is recommended that the company should fully amalgamate to a computerized system. The proposed system should have the following features: -

1. Entry system should be automated as processing time could be reduced, increasing the efficiency of the sales department.

2. Statistical Tools should be provided; this helps in better decision-making.

3. Interfaces should be made user-friendly.

4. One of the most imperative features should be added is the generation of reports.

5. Security and other human errors should be dealt.

FEASIBILITY REPORT

Operational Feasibility

Our Feasibility follows the PIECES Approach.

• PERFORMANCE

• INFORMATION

• ECONOMY

• CONTROL

• EFFICIENCY

• SERVICE

The current System running in MCR Pizza Hut is an MS-Office based System. Proposing to upgrade them to an SQL / VB.NET Frame based System.

PERFORMANCE

The throughput of the existing Semi-Automated System is within the required time. This system takes about 15 – 20 minutes. After the Upgrading of the Existing System the Response time will effectively decrease as the Sale and the Order will be integrated within. The Proposed system will generate customized reports accordingly.

INFORMATION

The Semi-Automated System being used is very complicated in the sense that most of the information stored has to be searched manually. No customized reports, human errors are high and most of all the very high number of Excel sheets to maintain.

The Proposed system can do much of what an MS-Office based couldn’t do. More Effectively in Report generation and Customization with e-mail Integration. Access to a particular record can be easy completely user friendly with less human errors. The System will not only save time n money but also be able to interact directly within the Hut as it will be based on a back-office system.

ECONOMY

As stated above the semi-automated system being used is not interlinked, and due to this the cost may increase and so as the time.

The Proposed system will deal in all this as it’s a back-office system. Any Order or Sale will directly reflect into the database generating customized reports. This will save time and money reflecting in profits.

CONTROL

The current System is moderately effective as only the Manager himself is the only person using the system. Though the system being maintained is not that effective in security measures.

The Proposed system may deal with all the security measures as assigned accounts may be given to each employee. The data will be in complete safe and sound as authorized personals will only be given the rights to the main data.

EFFICIENCY

The Proposed System will benefit not only the managers but all so scuttle to its inclusive extent. This System will decrease the processing time saving money and other preliminary costs.

SERVICES

The existing system is not at all expandable, desirable or flexible enough. The system does not provide complete required business resources to the concerned Employees and thus is not that effective.

The Proposed system will look into all the backgrounds required for the system. The new system will be flexible and more desirable effectively providing resources to the concerned employees. The system will be expandable as well.

USE ABILITY ANALYSIS

Use ability analysis is often performed with a working prototype of the proposed system.

EASE OF LEARNING

The New Proposed System will take about 2 – to – 3 days to learn as the system is completely user-friendly. The user can easily interact with the system within a day or too due to its user-friendly interface design and implementation.

EASE OF USE

The user will be able to perform the activity quickly and accurately even if the user is not a frequent one he / she will be able to do it because of the user-friendly interfaces which are understandable. If a frequent user then the productivity and efficiency are adorn ably increased.

TECHNICAL FEASIBILITY

Technical feasibility looks at what is practical and reasonable.

Major Issues:-

1. Is the Technology or Solution Practical?

The Proposed Technology is very much feasible and normally available. The Proposed Technology solution is easily applicable for the problem as is also expandable.

2. Posses the Necessary Technology?

The Technology solution is practically available commonly. This show that the proposed solution is very much in use and also excepted professionally.

3. Posses the Necessary Technical Expertise?

The proposed system does not lack in any case. The Employees will easily be able to interact with the new system as it will be more interactive and user-friendly.

ECONOMICAL FEASIBILITY

PERSONAL

No Person Rates / HR Total

1. System Analyst / Project Manager Rs.700 26,000

2. Programmer / GUI Designer Rs.55 18,000

3. Database devp / Telecom Rs.300 15,000

4. Network Admin Rs.120 10,000

Service charges Rs.5,000 yearly 54,000

Total 54,000 + 5000

DIFFERENT SOFTWARE ACCESS

VB.NET & MS-Access VB.NET & SQL SERVER

Performance

VB.NET Provides powerful interfaces and easy to use applications. Together with Ms-Access it provides a complete solution but minimum security. Though this is very much economically feasible compared to the other solution. Performance

VB.Net develops rapid and easy to use application and when merged with the database developed in SQL provides maximum security. As compared to the other this solution is quite very much expensive but most experts recommend this solution.

Total Cost

Rs. 35,000 + 35,000 + 7000 (service charges) Total Cost

Rs. 65,000 + 55,000 + 9500 (service charges)

Problem

At the present time, the current system is running on an MS-office based application causing strain. The load and size of the application clearly causes in efficiency, increased workload without reaching a complete automated solution to manage the organizations rapid success.

There are many points of entry, no central coordination, (the same system runs in all the restaurant branches and the main office).No customized requirements can be fulfilled. This non-system results in frustration and strain.

Proposed Solution

The new system will provide for a single point of entry (Intranet accessible), fast and accurate turn-around times, as well as the ordering scheduling, tracking, monitoring and communications between each branch and the main office.

The new system will also provide a complete back office system putting 0% chance for human errors. This will cut costs and improve process time between the restaurant and its customers, and the organization and the outside world. The system will also be providing e-mail integration with the system

Goals

Back office integrated system

Single Point of Entry

• Intranet Interface Centralization of data

• Accessible across the organization

Process

_________________

Method Data Capture Data Entry Data Processing

Keyboard Data usually captured on a business form that becomes the source document for input Data entered via keyboard. This is the common input method but prone to errors OLD: Data can be processed into batch files for batch processing.

NEW: Data is processed as soon as it has been entered.

Mouse Same as above Used in conjunction with keyboard to simplify data entry.

Mouse serves as pointing device for a screen .used with GUI interfaces. Same as above but the use of a mouse is commonly associated with online and real time processing.

Touch Screen Same as above Data entered on a touch screen display. Data entry users must use touch commands and data choices.

Point-of –Sale Data is captured as close to the point of sale. No source documents Data is entered directly by employee interacting with the customer. Inputs require special, dedicated terminals. Data is always processed immediately as a transaction or an inquiry.

Modular/Customizable user interfaces

Restricting data access/views, and module privileges by group /user

The various possible categorizations of the system provide the ability to customize the presentation of information by employee status .The system will also provide the functionality of assigning user profiles. For, example, employee with different access levels will be provided with standardized employee level profile.

Interfaces

Centralized/Automated administrative processes

Data capture

All related data and associated information will be contained in a central data repository (Main Office Database.)

Scheduling

The system must provide scheduling and tracking functionality for all sales activities. The functionality to log and track order (including follow-up letters, summaries, and reports).

Automated Notices and Email

Automated notices can be added to mark user requirements. (Sales decrease, appointments, ordering of items etc.) an Integrated e-mailing system with outlook express.
