The Stages Of The Waterfall Lifecycle Model Essay

This section gives the details and specification of the hardware on which the system is expected to work.

Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully. ("Mind Tools", 2012).

The information system’s requirements in the systems planning phase are based on a case summary, potential interview questions, and the systems analyst’s experience in systems planning. One must not only generate requirements based specifically on what users’ state they want or need. Analysts must also generate requirements based on insight into the overall organization and project goals.

Unlike upgrades and modifying existing systems, this new system does not require parallel installation. However, data cutoff, final conversion, and entry of queued work will occur.

Once a tool or vendor is determined the design team will work on implementing the design. The design will be implemented as part of the project plan timeline and Smith will provide developer testing in addition to end-user acceptance testing. This ensures that the final product matches the goals of the system as laid out in the project plan. Once acceptance testing is completed the system will be implemented and the system will enter its training phase as indicated in the project plan.

Then proposed system is been designed. Plans are prepared concerning with the physical construction, hardware, operating systems, and

Ans: We should be using multiple requirements elicitation techniques because in general we should divide our problem into two different types our objective is to make a perfect system

Design activities are closely interrelated and generally all done with substantial overlap. “During design, it is often necessary to verify the correctness or workability of the proposed design. One important verification method is to build working prototypes of parts of the system to ensure that it will function correctly in the operating environment.” Every system must have sufficient controls to protect the integrity of the database and the application program. These controls should be integrated into the new system while it is being designed, not after it has been constructed (Chapter 2, 2004).

Q1.Briefly explains following designing requirements that are required when designing the hardware and software infrastrucre.

What errors or problems will the new system have? The third stage is component design. For component design, we have to design the database and determine hardware specifications. The fourth stage is implementation. During this stage you have to build system components and conduct tests to see if it works properly.

After the proposed system is analyzed and designed, the actual implementation of the system occurs. After implementation, working system is available and it requires timely maintenance.

I will show what I consider as advantages and disadvantages of the waterfall model in the table below:

The current system is thoroughly understood, including problems, and complete documentation of the system—transactions, reports, and questions that need to be answered—are gathered. User needs that are not in the current system are outlined and documented. Users include everyone, from top management to data entry. The requirements analysis not only provides the developer with the specific needs, it also helps users accept the change. Users who have the opportunity to ask questions and provide input are much more confident and receptive of the change, than those who sit back and don't express their

Those steps are typical cycle of developing system methodology. For the steps to complete a cycle, it needs 3. Firstly, find out the mission, risks, and solution of design and limitations. Next, base on the target and limits to produce solutions. Lastly, this step will be let multiple persons evaluating the solution created by the developers and plan for another iterative phase, cycle. The cycle will repeat with simulate steps until the system exactly complete. Every cycle of it begins with some

It can provide guidance for developing the views of the architectural methods and for ensuring the set of requirements if properly
