SYSTEM ANALYSIS3 INTRODUCTION There is great competition in the hotel industry right now and every catering firm is struggling to meet all the customer’s expectations. This is not just about the quality of food that is offered. It is also much about how customers are satisfied with the processes involved. The processes include how food is ordered, served and how payment is done. The time taken to serve a customer is also very key. All of these are much dependent on technology. Using a paper based system to order food is now a thing of the past. Many will agree that such systems chase away customers as it really takes a long time to serve a single person in a very busy environment. Tasty Food Caterers need to upgrade their system which is utilized in ordering and buying food. This will help the firm make the ordering and payment processes faster and reliable. It is also a good marketing strategy as it will let customers refer other potential customers through email. After all, these are said and done, developing a system for Tasty Food Caterers involves other system design procedures. In this paper, I will provide the best method of the Software Development Lifecycle that is going to be implemented so as to guide through to the completion of the project. I will also provide a sample questionnaire used to gather requirements. I will also give three important diagrams describing the proposed system; they are the Use Case diagram, the ERD and the Data Flow Diagram. BEST SDLC MODEL TO USE In the past three decades, the waterfall model was the most used Software Development Lifecycle in the delivery of many projects. Anyone in the 90s would suggest that Tasty Food Caterers go for the waterfall model. At this time where many other SDLC models have been invented following the rapid pace of software development, I would recommend that TFC use the Iterative model (Islam et al., 2015). The reason for this is that Iterative development allows
SYSTEM ANALYSIS4 for adaptability in accommodating new necessities or changes thereof. This model is additionally best as it gives space to any improvements in succeeding iterations. REQUIREMENT GATHERING METHOD The one-on-one interview would be the best method of gathering requirements. This would be the most efficient method because the client will be involved directly since they are directly asked what they require in the new system. Open ended questions will be asked so as to get the interviewee to start talking and then ask probing questions in order to uncover requirements Sample Questionnaire. Please validate each of the statements below by answering “Yes” or “No” A.Would you want the total cost of the orders to be computed for you? B.If No, give a reason. C.Do you want the owner of this firm to track everything that is going on? D.Do you want customers to place orders by their own in the system? E.If your answer above was No, explain. F.Would you want that there be an option for urgent orders? G.Do you want the Chef to view all the orders? H.Can the customer alter the order after it has been given to the receptionist? I.Do you want the system to send notification emails to customers? Answer all these questions. J.How will the customer pay? K.How will the customer know the status of his order? L.When should the customer pay for his order? M.How will you implement discounts?
