Subject: SDLC phases
The testing phase in ERP implementation could not be skipped. Each phase in SDLC is equally important.
The phases of SDLC are shown below:
Systems development life cycle (SDLC):
- The seven phases in SDLC includes:
- Planning phase:
- The planning phase includes creating a goal statement for project.
- It defines a high level plan for intended project.
- It sets the scope of project.
- Analysis Phase:
- In analysis phase the firm would analyze business requirements.
- It refines goals of project into defined operations and functions of intended systems.
- Design phase:
- The design phase creates description for system features and operations.
- Development phase:
- The development phase transforms detailed design documents into actual system.
- During this phase, the team defines

You are appointed as CIO for a well-known hospital. The medical staff of the oncology ward would like to build an expert system for diagnosis. Your preliminary review shows that the financial investment would be great. You have the options to use either System Development Life Cycle (SDLC) or enduser system development or prototyping approach to build this system. State the choice of your approach and cite the reasons behind your choice.
Simple Guidelines For How to Answer the Question:1.To choose either one of SDLC or Prototyping approach (To build the oncology diagnosis system);2.Firstly, simple explain why we choose this approach (Depend on which you choose: SDLC or Prototyping);3.Secondly, to justify and cite the reasons (Four[4] reasons) why we choose the approach. (Need to have Four [4] strong justifications.)

2. Your company is considering using N-version programming with three software development firms and three hardware devices for the navigation system of a guided missile. Briefly describe what this means, and outline several advantages and disadvantages of this approach.
3. Your organization develops accounting software for use by individuals to budget and forecast their expenses and pay their bills while keeping track of the amount of money in their savings and checking accounts.

Background
You are a systems analyst contracted by Earth Friendly Babies, a mail-order company that sells earth friendly baby products. You and your consulting firm have recently completed development of a new system for managing orders and inventory for Earth Friendly Babies. System architecture already has been decided, and you are ready to embark upon installation, evaluation, and training for the new system.
Earth Friendly Babies has grown from an at-home business set up by a stay-at-home mom to a small mail-order company that sends out catalogs to 10 states, employs 5 people in addition to the business owner, and has office and warehouse space in an office park designed to encourage small businesses. The business has relied upon manual data collection methods for taking orders, billing, and managing inventory. The new IS will provide the support necessary for the company to expand to all 50 states with their mail-order campaign. None of the employees has worked with an IS system…

- It is perhaps not surprising that Etsy was an early adopter of DevOps. It is a relatively small company, with a start-up culture, and its move to DevOps was championed by company leaders. Do you think deploying DevOps practices would be more difficult in a larger, more established organization? How might a company begin to make the cultural changes needed to move to the more collaborative, rapid-deployment approach that DevOps offers?arrow_forwardBackground You are a systems analyst contracted by Earth Friendly Babies, a mail-order company that sells earth friendly baby products.

- 3. Assume that you signed up for freelance service for the first time. To prove your capabilities, you decided to add some dummy software development projects as showcases of your work. In each project, you proposed that a client has contacted you for a program, application, information system, or app to be developed. Thereby, you and the client need to agree on the boundaries and type of the project you are about to accomplish. In this task, each student can select a software project from any domain, size, or type. Each student must write and submit the following: 1- A description of the software project, and 2- include a problem statement that explains the problem which the project will study or solve.arrow_forwardWhat sequence would make the most sense for a systems architect to approach defining a suitable solution for a business problem? Group of answer choices Define the algorithm, select the programming environment that supports the hardware best, Define the user interface based on AB testing surveys Define the data requirements first, then design and information architecture that contains the data, finally select computing platforms that works with the information design Select the best hardware you can afford, choose the fastest database possible, write Java code to solve the problem Understand the information needs, define the data requirements, select hardware and technologies to support the necessary systemsarrow_forwardYou are gathering requirements for a new version of an existing product that is presently being developed. List one elicitation approach that would be successful in resolving each of the following section's needs elicitation problems (one technique per problem). Briefly explain why this technique is suitable in this circumstance. Rather of just listening to what users claim they do with the existing system, you should examine how they really use it.To accomplish so, you must first determine which elements of a new proposed system are the most important and necessary.arrow_forward
- K. Choi, chief financial officer for Petrie Electronics, came early to the quarterly IS Steering Committee meeting. Choi, who was the chair of the committee, took his seat at the head of the big table in the corporate conference room. He opened the cover on his tablet PC and looked at the agenda for the day’s meeting. There were only a few proposed systems projects to consider today. He was familiar with the details of most of them. He briefly looked over the paperwork for each request. He didn’t really think there was anything too controversial to be considered today. Most of the requests were pretty routine and involved upgrades to existing systems. The one totally new system being proposed for development was a customer loyalty system, referred to internally as “No Customer Escapes.” Choi chuckled at the name as he read through the proposal documents. “This is something we have needed for some time,” he thought. After about 15 minutes, his administrative assistant, Julie, came in.…arrow_forwardIdentify two functional and two non-functional requirements the system should provide Identify two quality attributes the new system should hold.

Its owner and Managing Director, Warren Randall, runs the business fromhis farm where he and his staff rear the goats and make the ice cream which is sold to farmshops, delicatessens, restaurants and schools across the East of England. The herd nowcomprises some 300 mainly Anglo-Nubian goats and is maintained by Head Goatherd,Malcolm Illingworth, and five other stock workers who also undertake the twice-daily milkings.Under the supervision of Production Manager, Rachel Scott, the team of ten food techniciansmanufacture the ice cream in over forty flavours (some as stock items and some made to orderonly) and package it in 5 litre napolis, for serve-over…arrow_forwardWhen should a systems analyst decide a design issue, and when should users be allowed to select what works best for them? The field of ergonomics is concerned with improving the work environment and studying how users interact with their environment. Suppose you are a systems analyst studying the order processing system at Boolean Toys, a fast-growing developer of software for preschool children. You know that many data entry users have complained about the input screens. Some users would prefer to rearrange the order of the fields; others would like to change the background color on their screens; still others want shortcuts that would allow them to avoid a series of introductory screens. What if Boolean’s users could customize their own data entry screens without assistance from the IT staff by using a menu-driven utility program? What would be the pros and cons of such an approach?arrow_forward
