CASE STUDY PART 2

At your first meeting, you and Wendy discussed some initial steps in planning an information system for the property. The next morning, you worked together on a business profile, and talked together about various types of information systems that could provide the best support for handling their customers’ needs, and mindful that there was a need to also track certification documentation to demonstrate the fully ‘organically produced’ nature of the farm produce. You also discussed the longer term plan to expand the operations of the farm to include farms that supplied fruit, which would also have to be demonstrated to be fully ‘organically produced’.

You start by creating a System Vision Document for “Natural-Lee”, so that Wendy can use this to define a vision for the new system and present this to Phil.

ACTIVITY 2

1. Either by yourself or with another class member, brainstorm all the functions that the “Natural-Lee” Information System might fulfil. Keep it at a very high level.

2. Prepare a draft System Vision Document for the Farm Information System. This System Vision Document will be revised when you find out more about the requirements for the system. An example System Vision Document can be seen in Figure 1.8 of the textbook (Figure 1.5 in the 6th ed).

3. Add your System Vision Document to your Report document in Part A: Initial Investigation.

“Natural-Lee” Case Study ISY00243 - 2019 S2 Page 10

You have been given a little information about what is required but there are a lot of gaps. You are expected to fill these gaps to work out details and additional information that is needed. This also gives you some latitude to explore farming and their operations as they apply to your background and experience. Make sure you explore other vision documents and know how they are worded and what needs to be expressed in them so that an organisation knows where it is headed and what it is trying to achieve.

Part B
1) Recommendation and Fact Finding
Requirement analysis can be said to document and analyses the requirements of the system. The first step of this is to analyses the problem. Once we understand the problem then only, we can look for the solution. It is possible that the developer may make some mistake in analyzing the problem. There are certain basic effective methods or facts finding which can be used to eliminate the error.
Fact Finding is the process of collecting data and information using the techniques. These techniques can be sam
ple of existing documents, observation, questionnaires, interviews etc. Finding the facts about a project is important so that we can chose appropriate tool from Software Development Life Cycle and use it efficiently. The fact finding helps in initial phases like design and plan of the project in the Software Development Life Cycle. Facts which we find out can be tested upon following three points:
Data- Facts used to create useful information
Process- functions to perform objectives
Interface- Designs to interact with the users.
1) Sampling of existing documentation, forms and databases
The best way to get the facts about any system is to analyze the existing system. There are various documents like emails, customer feedback, suggestion and report which can be collected about the existing systems. The system analyst uses sampling techniques to organize these documents.
2) Research and site visits
This is the second method to examine the already existing system solved either by human or document.
3) Observation Of work Development
In this system the system analyst is allowed to participate in the organization. He will compare the existing model with the new model idea.
4) Questionnaires
In this process we can ask questions to the different users and their response can be recorded. It also saves the analyst’s time also as they don’t have to interview each person and interview can be small by preparing the questionnaire. It only requires that analyst must have a good knowledge to precisely design and frame the questionnaire.
5) Interviews
The interview means the face- to-face question and answer round. The purpose of this interview process is to find, clarify, verify, identify requirements and gather ideas. A communication skill is important part for system analyst and also for the user.
I have used the questionnaire tool to find the facts and requirements about the project. There are two types of questionnaire.
Free format questionnaire- Users are allowed to answer they want to do. It not compulsory to answer at the same time when the question is asked. They respond is helpful in understanding about the feelings and opinions of the respondent.
Fixed format questionnaire- There is a permanent format in which the user needs to answer. Users can opt out for an answer from the given options. There are three types in which user can answer- choice questions (Yes or no), rating (strongly agree to strongly disagree) and ranking (numbering according to the preferences).
Advantages
This technique is inexpensive. Users can submit their answers whenever they want. No personal information to be shared by the users related with them so they answer the questionnaire correctly. Having few types of answers, they can be easily calculated and examined.
Disadvantages
Good questionnaire is difficult to prepare. It is the most important and difficult part of this tool. Analyst cannot understand the body language of each user and there may be chances that user does not submit the complete answers. Analyst cannot define incomplete answers.
2) Fact finding interview Plan
There is a long list of questions regarding a project which can’t be finished in single meeting. The analyst must manage 3-4 meetings. Even after first meeting we find that the answers are not so clear so further meetings are helpful in getting better output. We should prepare a questionnaire which include both open and closed questions. Open questions mean the questions with long and descriptive answers while the closed questions are just opposite to that. They are simply yes, no types questions. Here are some questions which can be asked to Wendy regarding the project.
1) Tell me about your farm and the business model idea.
2) What kind of information management is required?
3) Why orders are always taken on phone?
4) Why Phil doesn’t give suggestions from last orders?
5) How many fruits do you have?
6) Who among Wendy and Phil have fruits and vegetable?
7) What are practical reasons for not having both?
8) Are you organic-only and how?
9) How an information system can help in doing so?
3) Use Case Diagram
It belongs to the family of behavioral diagrams from unified modelling language. It is a diagrammatical representation of what a system has the capability to perform but it doesn’t answer the how for that system. It will explain all the operations a system can perform. For example, according to the given case study, the system will be designed which will allow the user to register or login, search for products, if found then place the order and make the payment. Once the payment is confirmed then delivery person will take the order for delivery to the client. The use case diagram consists of actors who will use the system and use cases in eclipse shape which will be performed by the system.
4) Use case description
This is used to provide a description for the activity that a particular actor will perform...
