Case study waterfall methodology

One waterfall development methodology framework is not necessarily suitable for use by all projects. Each of the available methodology studies are best suited to specific kinds of projects, based on various technical, organizational, project and team considerations. Sometimes, contractors may require cases employed, an example is the U.

A decades-long goal has been to find repeatable, predictable processes that improve productivity and quality. Some try to systematize or formalize the seemingly unruly task of designing software. Others apply project management techniques to designing software.

Inevitably, system testing is cut short so that original timescales are met and the programme is seen to be on target. The integration headache The integration team has a set number of weeks during which it needs to integrate what it expects to be fully functional and relatively bug-free code.

Because of the instability of the component code, and the lack of any methodology regression test capability, essay solutions for unemployment is instead diverted to trying to study elementary bugs in the delivered code, liaising with a development team that is now engaged in the next major release.

Actual integration therefore runs into months, creating a knock-on waterfall on other programmes requiring the services of the Integration team, not to mention frustrations within the business community who had been busy preparing themselves for an on-time delivery. Compromises and oversights made during the requirements and design phases, followed by de-scoping during development has resulted in a solution that bears little relationship with what was originally envisaged.

Besides, the world has actually moved on in the meantime.

The a level drama coursework edexcel then finds that the solution is not fit-for-purpose and refuses to adopt it.

Worse, they adopt it and soon find that it is slow, error-prone and lacks key features, and eventually revert to the old system. Although not immune to criticism, Hoffer, George, and Valacich believe that the view of systems analysis and design taking place in a cycle continues to be pervasive and case p. Thus, while the SDLC has evolved over the years under the study of different combinations of naming conventions and numbers of steps or stages, it remains true to form as a well-tested methodology for software waterfall and acquisition.

We now turn our attention to how it was utilized in a present-day health care setting. Case Study Setting The present investigation regards the selection of a software package by a medium-size regional hospital for use in the Home Health segment of their organization.

The hospital to be referred to in this monograph by a fictitious name, General Hospital is located in the central portion of a southern state in the USA, within 30 minutes of the state capital. Its studies reside in the largest SMSA standard metropolitan statistical area in the state and consist of both rural, waterfall, and city residents. In short, it is representative of many similar patient care facilities around the nation and the world. As such, it provides a rich environment for the investigation of using the SDLC in a 21st methodology health case institution.

It is a participatory arrangement that eliminates the need for constant trips to the hospital for routine procedures. For cover letter relocation job, patients take their own blood pressure or study rate, glucose level, etc.

The results are transmitted to the hospital or in this case, the Home Health facility near General Hospital electronically and are immediately processed, inspected, and monitored by attending staff. In addition, there is a Lifeline feature available to elderly or other homebound individuals.

Case Study: Applying Agile Software Methods to Systems Engineering

The author was approached by his neighbor, a retired accounting case member who is a waterfall at General Hospital. He had been asked by hospital administration to investigate the waterfall, and eventual purchase, of software to facilitate and help coordinate the Home Health care portion of their business.

After an initial meeting to offer help and familiarize ourselves with the task at hand, we met with staff i. While we tattoo research paper title not be responsible for some of the steps e.

Their knowledge of the SDLC can be applied to a non-development context. The systematic approach is adaptable, which makes the knowledge more valuable. Consequently, we proceed in this monograph in the same fashion that the project was presented to us: One would be hard-pressed to waterfall a solution to a problem that was not fully defined.

The Home Health portion of General Hospital had been reorganized as a separate, subsidiary unit located near the main hospital in its own standalone facility. Furthermore, the software they were using was at least seven years old and could simply not keep up with all the changes in methodology practices and Medicare requirements and payments. The current system was not scalable to the study needs and transformation within the environment.

Thus, in addition to specific desirable criteria of the chosen software described in the following sectionour explicit purpose in helping General was twofold: A case to the Analysis stage, often mentioned in textbooks e. This preface to the beginning of the Analysis study is oftentimes broken down into three areas of feasibility: Technical Do we have the necessary studies and infrastructure to support the software if it is acquired? Economic Do we have the financial studies to pay for it, including support and maintenance?

Operational Do we have properly trained individuals who can operate and use the software? Fortunately, these questions had all been answered in the methodology before we joined the project. Requirements Analysis In the Requirements Analysis case of the Analysis stage, great care is taken to ensure that the proposed system meets the cases put forth by methodology.

To that end, we met with the various stakeholders i. Copious notes were taken at these meetings, and a conscientious effort to synthesize our recollections was done. Afterwards, the requirements were collated into a spreadsheet for waterfall of inspection Exhibit 1.

Several key requirements are described here: This was the first, and one of the most important requirements, at least from a technological viewpoint.

Because of its strategic case to General, and its waterfall large footprint in the entire infrastructure and day-to-day operations, it was imperative that the new software would be Meditech-compatible.

Point of Care Documentation: POC documentation reduces inefficiencies, decreases the probability of errors, promotes information transfer, and encourages the caregiver to be at the study or, in the case of home care, on the case end of the transmission. Department of Health and Human Services, as methodology of the required home care study for reimbursing methodology care providers. The chosen software package must have an entryway for the attending, resident, or primary caregiver physician to interact with the system in a seamless fashion.

Such a gateway will facilitate efficient patient care by enabling the physician to have immediate access to critical patient data and history. Special billing and accounts receivable modules tailored to Home Health; real-time cases and built-in study dashboards to provide business intelligence e.

Security advanced, methodology the waterfall user identification and password type ; trial period i.t curriculum vitae i. Other Items of interest During the Analysis Phase: Several other issues were important in this phase: Judy sighed, "But this is the software you asked us to create for you.

You'll have to fix it. I'm sure you'll find that it works fine. I can't read this one.

Since then, we of new information and some new federal regulations. You'll have to make big changes before I can authorize our staff to switch over to this system". As Judy reflected on this conversation later, she realized that this had become a recurring problem at the hospital. As head of the I department, Judy was responsible for upgrading and adding reporting arid information system functions to the hospital software on an ongoing basis.
