WATERFALL MODEL OVER PCD.UCT MODEL REVIEW

N S Wisidagama, Faiz Marikkar · Automation technological and business processes · 2024

Abstract. The software development life cycle (SDLC) has seen the evolution of numerous models, each tailored to meet specific project needs. Among these, the Waterfall Model has been a longstanding, traditional approach, characterized by its linear and sequential phases. In contrast, the PcD.UcT Model, a relatively newer framework, advocates for a more iterative and user-centered approach. This paper presents a comprehensive review of the Waterfall Model, evaluating its strengths and limitations in modern software development. It contrasts these findings with the PcD.UcT Model, analyzing how its principles better align with contemporary project demands, particularly in terms of flexibility, user engagement, and iterative refinement. Through this comparative analysis, the paper aims to provide insights into the applicability and effectiveness of each model, offering guidance for software development teams in choosing the appropriate methodology for their projects. Since the waterfall development methodology, the key requirements in system development strategies have shifted from processes to users. Because the process as well as the customers are both equally important, employing either a predictive or an adaptive methodology is extremely difficult. The primary goal of this work is mainly combining and then evaluating all the relevant methodologies in order to create a HydroGIS that accurately automates the complexities of the hydrology process in a HydroGIS environment while meeting all user requirements.

Pengembangan Aplikasi Kasir Menggunakan Model Waterfall

Aji Saputra, Cut Fera Inong Safitri, Fitriyani Fitriyani et al. · Jurnal Teknologi Sistem Informasi dan Aplikasi · 2021

Many companies engaged in printing services still use manual processes in their transactions, the system process is less efficient and the possibility of errors in input data can still occur. Like the process of recording orders using paper, calculations using calculators and sales transactions written on books. Therefore, for these problems, a cashier application is needed that can facilitate the order process, calculations and transactions accurately with a web-based cashier application that features login, sales transactions, product data, add products, settings and exit applications. Our development process uses the waterfall method and to describe the system design we use the Unified Modeling Language (UML). Application using the waterfall method can make it easier to complete the application development process because there are already stages in the method.

Inventory Control System Using Waterfall Development Model

Mohd Talmizie Amron, S. Hassan, Mohamad Shukri Saleh Hudin et al. · International Journal of Engineering & Technology · 2018

Information system innovation progress is turning out to be speedier and simpler to use. In many cases, there are an organization that still utilize the customary route in preparing their information. Customary routes will require people to move from one place to another to achieve their goals. In the case of Finance Department, UiTM Kampus Kuala Terengganu, the manual process involving the staffs to fulfill and submit the form and officer will approval and validation. The storekeeper will verify the availability of the item in the store. Using manual processes consumes a lot of time, high risk of human error and involves a lot of papers as well as files. Therefore, Bendahari Inventory Control System (BICS) was proposed to help the Finance Department to be more systematic in handling the inventory control. The implementation of the Waterfall Model in this research was turned to be useful and appropriate to help building up the system. Â

PERBANDINGAN MODEL WATERFALL DENGAN RAD BERBASIS WEBSITE

Fanie Rachman Cahyadi, Moch. Arief Sutisna · Jurnal Ilmiah METADATA · 2023

Pengembangan sistem perangkat lunak selalu dihadapkan pada pemilihan metodologi penggembangan sistem yang sangat beragam, hal tersebut menimbulkan kebimbangan bagi pengembang, karena jika salah dalam menentukan pemilihan metodologi dapat mempengaruhi sukses atau tidaknya pengembangn sistem ini. Penelitian yang digunakan penulis adalah menggunakan data dari penelitian terdahulu, mengulas jurnal, dan dikomparasi, dengan kata lain penulis menggunakan metode deskriptif. Berdasarkan penelitian didapatkan hasil bahwa metode waterfall tidak cocok dengan model penggembangan yang tinggi karena tahapnya tidak dapat berulang, mahal dan waktu pengerjaan dilakukan secara bertahap, sedangkan metode Rapid application development (RAD) cocok untuk proyek besar karena menggunakan metode iterative (berulang) dan dapat menghemat biaya

Waterfall Model Simulation: A Systematic Mapping Study

Antonios Saravanos · arXiv (Cornell University) · 2025

This paper systematically maps peer-reviewed research and graduate theses/dissertations that explicitly simulate the waterfall model. Following Petersen's mapping guidelines and Kitchenham's systematic literature review practices, major databases (ACM Digital Library, IEEE Xplore, Scopus, Springer, Google Scholar, and Web of Science) were searched for studies published between 2000-2024 using the title query ("simulation" OR "simulating") AND "waterfall". A PRISMA workflow guided the screening process, and approximately 9% of retrieved records met the inclusion criteria. A repeated extraction process captured methods, tools, venues, geography, publication years, comparative scope, and fidelity to Royce's original model; findings were synthesized thematically. Discrete-event simulation dominates (80%) compared to system dynamics (20%). Reported tools center on Simphony.NET (40%) and SimPy (20%), while 40% of studies omit tool details, limiting reproducibility. Research is distributed across Italy, Lebanon, India, Japan, and the United States; publication venues include 60% journals and 40% conferences. Sixty percent of studies are comparative, while 40% model only the waterfall approach. No study reproduces Royce's original model; all employ adaptations. The paper concludes by presenting a consolidated view of waterfall simulation research and recommending clearer model reporting, fuller tool disclosure, and wider adoption of open-source platforms.

Dante’s Waterfall: A Hybrid Model of Inflation

Anuraag Sensharma · 2015

Given recent observational results from the BICEP2 and Planck collaborations regarding the ratio of power in tensor to scalar modes in the cosmic microwave background radiation, and the implications of this ratio for the possible existence of large gravity waves resulting from inflation, it is of current interest to investigate models of inflation which are capable of producing large gravity waves. We examine a hybrid axion monodromy model we call “Dante’s Waterfall”. In this model, the inflaton rolls slowly along a trench in the potential, and inflation ends when this trench becomes unstable and the inflaton rapidly approaches the global minimum of the potential. We find that this model is incapable of producing large gravity waves. We then introduce a vector interpretation of inflaton motion along a potential, and show that this can be useful in considering non-trivial kinetic terms which could give rise to large gravity waves in a hybrid model.

Breathing new life into the waterfall model

Christopher M. Lott · IEEE Software · 1997

Due diligence-it's a concept that savvy investors and investment bankers understand. Before you invest in something, spend the time to fully understand the people and the business. Only proceed after you're convinced that everything is okay. The author discusses a form of due diligence that can be applied when software development work is contracted. He argues that both the contractor and the customer should shape their interaction in stages, so that risk is reduced and requirements stability achieved before either party commits large sums of money.

Breathing New Life Into the Waterfall Model

Christopher Lott Bellcore, Christopher M. Lott · 1997

this article has convinced you that staged contracts are something your organization should investigate, here are some guidelines for making the transition from a conventional contract approach. If you are a software producer, begin by checking your organization's cost-estimation and resource-management skills. The key to winning contracts while still making money on the stages is staying within budget, so estimates must be very good, and the resources must be managed carefully once the contract has begun. Next, both the customer and the contractor must involve the people who write their contracts. Contractual obligations and ownership of intellectual property must be treated carefully. For example, the customer may demand the right to receive a detailed design document that could be taken to a different contractor. Of course the people who prepare and review technical documents such as the requirements deliverable must be involved. Contractor personnel must walk a fine line between recommending generic and proprietary solutions. A proprietary solution frequently offers the most bang for the buck, and (to the contractor 's delight) locks in a customer for later stages. However, as a customer you may be well advised to demand a generic recommendation in addition so that you understand the functionality of any proprietary solution. Finally, your organization 's method of operations for software work may require tailoring. For example, unlike the traditional proposal phase, stage 1 will yield thin requirements and possibly preliminary design deliverables, and the early availability of these controlled documents must be treated appropriately
