A system analysis consists of both manual and electronic methods. Figure 1.0 below shows a comparison of both of them.

The comparison of Manual and Electronic
The electronic system is clearly going to faster and reliable with an ever-increasing volume of documents; participants in the business process are looking for better, faster, and more efficient methods to get their work done. In order to keep up with greater document volumes, people are turning to digital document automation. Many recent efforts are looking to electronic recording to save time and increase both accuracy and efficiency. Electronic recording seeks to bridge the automation gap, providing a way to prepare and record documents without physically handling the paper Lewin Sports Shoes Ltd will prefer dealing with their work electronic recording because it is suitable for handling with large quantity of different shoes stock. Manual recording will take up often amount of time dealing with paperwork this will not be suitable for Lewin Sports Shoes Ltd.

This section will explain the stages in the development process.
Systems analysis is part of a continuous cycle consisting of six processes called the systems development lifecycle. The procedure of systems analysis is used when designing a new system or evaluating an existing system. The result of the systems development lifecycle is valuable information about what will be needed in a new system and how it will work or in the case of an existing system, what its shortcomings are and how it could be improved. The diagram below shows the systems development lifecycle and its individual processes:
The figure 1.1 shows stages involved in a development process:

The steps that I will be concentrating on that are related to task1 are the first three, which are:
Feasibility study:
As this is a new system then a Feasibility study is not needed.
If Lewin Sports Shoes did have an existing system then a feasibility study is an essential stage of the development of any project and particularly a sports project like Lewin Sports Ltd. It is primarily used as a tool to help the design team to make up its mind about the real need and aspirations of the client and what is feasible within the constraints of site, management, time and budget. The output of a feasibility study should be a strategic brief, possibly with a relevant outline plan that can be developed into a full building project.
System investigations:
In this system investigation my aim will be to have a one on one interview with my client who is Tim and the purpose of this is to find more detailed information about the new proposed system. The type of information I will find out will be based on as followed:
∙ Information about the company procedures – how certain tasks are they going to carry out.
∙ Measurements such as the size of the new system and how wide it will encompass the different areas of the business.
∙ How the company will benefits proposing this new system and their objectives towards introducing this system.

Lewin Sports Ltd order service – Interview
Michael: What would you like from the new system?
Tim: Lewin Sports Ltd is a newly established company. We are intending to market and sell different shoe types. Our aim is to implement a new system, which will enable for us and for our customers to obtain price quotation. The system should make our ordering more easily and efficiently.
Michael: Would you like your new system to control the stock – perhaps, to let you know what shoe is moving fast or slow?
Tim: Presumably, Yes – the system should keep track of all sales and alert us when shoes is running slow or fast in order for us to purchase all the shoes. I am going to display the invoice of the shoe on screen, so that we can assist the customer’s payments, and we don’t have to go and look for the price of the shoe.
Michael: In the new business, are you going to deal with customer’s credit cards?
Tim: Yes, we are probably going to deal with customer’s credit cards.
Michael: Can you tell me briefly about the scope of your proposed system?
Tim: I am willing to introduce the system mainly for our processing, invoicing and stock control.
Michael: Would you like to have a web site, so the customers could have the potential to see the latest shoe type and purchase shoes online also?
Tim: In the future, we are we should be able to expand the business the business into these areas, but for the moment we are not ready take up that level.

System Analysis
The current system at Lewin Sports shoes Ltd is a paper-based one for the purposes of simulation, which is as follows
In the current system all records are papers based so a scenario will be that a customer enters the shop and enquires about a pair of shoes. The shop assistant will consult the inventory from the last stock check and then enter the stockroom to attempt to find the shoes. If the shoes are in stock the shop assistant hands them to the customer for approval. If they decide to purchase a transaction takes place and the shop assistant will manually update the stock and account files.
If the desired shoes are not in stock the shop assistant will ask the customer if they wish for them to be ordered and reserved for them. If they agree the shop assistant will take their details and add them to the orders file. The customer will return later or be notified when their shoes are in stock.
In theory the system is simple and would seem to work but problems would soon arise, mainly due to the large amount of paper generated by the system.
Records can become unorganised if the shop assistant does not have much administrative experience and to hire a full time administrator to handle and organise the files would increase costs dramatically.
When the files become unorganised stock levels will not be correct and orders may not be processed. As a result customers will be lost and there will be a much lower level of efficiency.

These three steps are more related to Task 2, which is design.
System design:
Systems design is the evaluation of alternative solutions and the specification of a detailed computer-based solution. It is also called physical design (This explained more on page 6).
Systems analysis primarily focused on the logical, implementation-independent aspects of a system (the requirements).
Systems design deals with the physical or implementation-dependent aspects of a system (the system's technical specifications).
Systems implementation:
Design, write and test computer programs.
Create databases and convert existing files.
Writing of user documentation.
User training. Conversion to new system.
Review and maintenance: Test new system and make fine adjustments.
Ask if new system is necessary.
1.3
In a System design there are strategies used like RAD and OOD lifecycle models.
Rapid application development (RAD) is the merger of various structured techniques (especially the data-driven information engineering) with prototyping techniques and joint application development techniques to accelerate systems development.
RAD calls for the interactive use of structured techniques and prototyping to define the users’ requirements and design the final system.
The developer first builds preliminary data and process models of the business requirements. Prototypes then help the analyst and users to verify those requirements, and to formally refine the data and process models.
The cycle of models, then prototypes, then models, then prototypes, and so forth ultimately results in a combined business requirements and technical design statement to be used for constructing the new system, which is very similar to Lewin Sport Shoes Ltd.
Object-oriented design (OOD) techniques are used to refine the object requirements definitions identified earlier during analysis, and to define design specific objects.
Based on a design implementation decision, during OOD that the designer may need to revise the data or process characteristics for an object that was defined during systems analysis. Likewise, a design implementation decision may necessitate that the designer define a new set of objects that will make up an interface screen that the users may interact with in the new system.
Both of these lifecycle models are very parallel to Lewin Sport Shoes Ltd in which they are both for new systems but the different with RAD and OOD to the new application of system is RAD and OOD has different stages within there process.
