Waterfall Model

In the daily life of the software we think of mobile phone computer and so on devices that we use in different ways on our devices. For companies, the management of business processes such as the supply chain of human resources is the system of measurement of efficiency and profitability rates. The production of software, which is not in need of personal need, but increasing in importance in the institutional sense, has changed the dimension with the fourth industrial revolution. As a manifestation of this, the waterfall model and the latest methodology have been included in the software development processes of the first period and there are a variety of sub-disciplines and agile methods. In this study, both methods will be examined and a comparison will be made.

The agile software development method performs based approach authorized with values, principles and performs which make the software development process more easily and in faster time. Agile methods which realize individual methods like Extreme programming, Feature ambitious Development, Scrum, etc. Scrum is one of the most prevalent agile software development frameworks. The admiration is caused by the abridged process framework and its emphasis on teamwork. The impartial of Scrum is to deliver working software and establish it to the customer faster and more frequent throughout the software development project. This paper can be used predominantly by the security managers, users, developers and auditors. End of this proposed system methods are used to embed the penetration testing in agile software development project.

Penyimpanan buku, artikel serta beberapa sumber referensi pada perpustakaan SMKS Bintang Nusantara saat ini mengalami kesulitan dalam pendataan dan pengelolaan buku maupun sumber referensi lainnya, dimana pendataan dan pengelolaan tersebut di catat dan disimpan pada aplikasi spreadsheet, sehingga tidak terencana dengan baik, misalnya saja jika terjadi kehilangan buku, maka tidak mudah untuk melacaknya. Jumlah pengunjung yang ada di perpustakaan juga tidak rapih karena pencatatan buku tamu dilakukan secara manual. Ketidakoptimalan sirkulasi perpustakaan di SMKS Bintang Nusantara ditambah lagi dengan minimnya SDM yang hanya terdapat satu orang petugas dalam melayani peserta didik yang akan melakukan transaksi. Hal ini lantaran perpustakaan belum memiliki petugas tetap, sehingga pelayanan sirkulasi dilakukan oleh seorang guru yang rutin bertindak sebagai petugas perpustakaan yang terkadang dibantu oleh guru yang lain, kemudian tidak jarang siswa mencatatkan peminjaman bukunya sendiri. Oleh karena itu penelitian ini untuk memeberikan gambaran dari model pengembangan sistem informasi perpustakaan sekolah berbasis web, dengan sistem informasi ini diharapkan akan mempermudah pelayanan dan akses informasi serta pengelolaan sirkulasi perpustakaan, seperti mempermudah pencarian buku/katalog, peminjaman dan pengembalian buku, dan pembuatan laporan.

For many years, most public government ICT (Information and Communications Technology) projects were carried out using the Waterfall method. The basic development life cycle format of Waterfall (Requirement Analysis, Design, Development, Testing, and Maintenance) meshed quite well with the rigid vertical -and usually functional- hierarchy and processes of the classic public government entities.

However, in recent years, other methodologies have proven to be more effective especially in ICT projects, the most predominant being Agile. Therefore, a number of government agencies all around the world have been trying to apply the Agile methodology to their own ICT projects. Nonetheless, Agile has fundamental differences with Waterfall in its implementation: the lifecycle is repeated iterations that contain stages of Requirements, Plan, Design, Develop, Release, Feedback, Adjust, repeat. This format, along with the implementation speed and requirements of the methodology, require a different structure of the implementing agency, such as matrix or projectized, rather than a strictly functional structure.

The scope of this dissertation is to compare the two methodologies, under the assumption that they are applied to government and private sector ICT projects, discover their pros and cons, match their implementation lifecycle stages with the structure of a typical government agency and a private company, and culminate with results of the above analysis. These results are complemented with real-world data from ICT projects implemented with either method, as well as the personal experience of the author.

Each application's quality is the finish results of how every step of the life cycle of software development has been managed. In order to achieve a good quality product, multiple teams and strategies are used. Software development is a crucial process that everyone is aware of. However, justice will only be done if all the phases are well involved in their respective ways. Different Software Development Life Cycle (SDLC) models are commonly used for the software development. The SDLC models supply a theoretical guide to software development. The SDLC models that are very important for the systematic evolution of the software in such a way that it will be delivered within the time limit & should be of good quality as well. The proper use of SDLC enables project managers to regulate the software's entire development strategy. Every SDLC has its disadvantages and advantages in deciding which model under which situation should be executed. This paper compares various popular life cycle models such as prototype model, waterfall, prototype, rapid development of applications, V-shaped model, spiral model & incremental model.

Tegal district has broad range of industries which spread over 18 sub-districts. These industries have been supporting the sustainability of the economic rate of Tegal district. Local government still relies on the manual census in collecting the industrial data. The census results are solely published by Badan PusatStatistik (BPS). The resulting information was published only in table form without any further information. Uneven distribution of industrial information to the public caused the market share of Tegal’s industry was not optimized. Thus, limit the opportunity to obtain any investment for expanding the industry. Geographic Information System is a computer system that can record, store, write, analyze, and display geographic data. The industry profile, production type, investment value, industrial sites and
location of village and sub-district in Tegal district could be obtained by using the Waterfall method through the geographic information system design.

Building owners, designers and constructors are seeing a rapid increase in the number of sustainably designed high performance buildings. These buildings provide numerous benefits to the owners and occupants to include improved indoor air quality, energy efficiency, and environmental site standards; and ultimately enhance productivity for the building occupants. As the demand increases for higher building energy efficiency and environmental standards, application of a set of process models will support consistency and optimization during the design process. Systems engineering process models have proven effective in taking an integrated and comprehensive view of a system while allowing for clear stakeholder engagement, requirements definition, life cycle analysis, technology insertion, validation and verification. This paper overlays systems engineering on the sustainable design process by providing a framework for application of the Waterfall, Vee, and Spiral process models to high...

Software engineering provides methodologies, concepts and practices, which are used for analyzing, designing, building and maintaining the information in a software industry. Software Development Life Cycle (SDLC) model is an approach used in the software industry for the development of various size projects: small scale projects, medium scale projects and large scale projects. A software project of any size is developed with the coordination of development team. It is therefore important to assign resources intelligently to the different phases of the software project by the project manager. This study proposes a model for the spiral development process with the use of a simulator (Simphony.NET), which helps the project manager in determining how to increase the productivity of a software firm with the use of minimum resources (expert team members). This model increase the utilization of different development processes by keeping all development team members busy all the time, which helps in decreasing idle and waste time.

Technological advancement in information technology applications allows the data recording process to become easier. Putra Mariyo Trading Business is a business institution that sells wood as a building material in various types and sizes. Data processing of incoming and outgoing goods in this business is performed only by writing goods data into a specific book. Consequently, some problems such as the loss of data and miss calculation in processing transactions usually occur. Therefore, in this research, we design a system to address the problems. The system is developed by following the Waterfall software development method. To build the system, we opt to use PHP programming language, CodeIgniter framework, and MySQL as the database server. To determine system reliability, this information system testing uses black box testing which focuses on the functional requirements of the system. To evaluate the performance of the system two testing steps i.e., black-box testing and System Usability Scales (SUS) are adopted. Black-box testing results show that the error percentage of our system is 0%. The SUS testing is conducted to obtain responses from users and the SUS score obtained is 70.1 indicating that the system is at the "good" level and reliable to use.

High energy consumption has become a critical problem for supercomputer systems. GPU clusters are becoming an increasingly popular architecture for building supercomputers because of its great improvement in performance. In this paper, we first formulate the tasks mapping problem as a minimal energy consumption problem with deadline constraint. Its optimizing object is very different from the traditional mapping problem which often aims at minimizing makespan or minimizing response time. Then a Waterfall Energy Consumption Model, which abstracts the energy consumption of one GPU cluster system into several levels from high to low, is proposed to achieve an energy efficient tasks mapping for large scale GPU clusters. Based on our Waterfall Model, a new task mapping algorithm is developed which tries to apply different energy saving strategies to keep the system remaining at lower energy levels. Our mapping algorithm adopts the Dynamic Voltage Scaling, Dynamic Resource Scaling and β-migration for GPU sub-task to significantly reduce the energy consumption and achieve a better load balance for GPU clusters. A task generator based on the real task traces is developed and the simulation results show that our mapping algorithm based on the Waterfall Model can reduce nearly 50% energy consumption compared with traditional approaches which can only run at a high energy level. Not only the task deadline can be satisfied, but also the task execution time of our mapping algorithm can be reduced.

ABSTRACT Organisational and cultural boundaries are two of the main important aspects of the software development process for distributed customers. Many organisations use traditional approaches, such as the Waterfall model, to develop software products for different customers. Agile software development has departed from traditional approaches, such as the Waterfall model. Much research has been conducted on adopting agile software development for either distributed or collocated projects. However, little research has discussed organisational boundaries between developers who use an agile software development approach and their customers. The purpose of this paper is to introduce agile software development to those organisations that develop software products for different distributed customers and also to study the potential impact of introducing Agile development across those organisational boundaries. We proposed a framework for developing software across organisational boundaries. This would ultimately address and accommodate key factors in software development across organisational boundaries using an agile development approach. This research will help the development society and serve as a guide for project managers, developers, stakeholders, and users to understand agile software development and the impact of adopting an Agile approach across organisational and cultural boundaries in their projects.

Kabupaten Tegal memiliki berbagai industri yang tersebar di 18 Kecamatan, industri-industri tersebutlah yang dapat menopang laju perekonomian pada Kabupaten Tegal. Pemerintah Kabupaten Tegal dalam melakukan pendataan industri tersebut masih mengandalkan sensus yang dilakukan secara manual. Data yang ditampilkan dari hasil sensus tersebutpun masih tersentral dipublikasikan oleh Badan Pusat Statistik (BPS) dan informasinya hanya berupa tabel-tabel tanpa visualisasi yang menarik. Kurangnya informasi industri yang disampaikan kepada masyarakat, menyebabkan industri-industri yang ada di Kabupaten Tegal kurang dikenal oleh masyarakat luas sehingga pangsa pasar industri Kabupaten Tegalpun tidak maksimal, disamping itu juga peluang untuk mendapatkan investor guna pengembangan usahapun menjadi terbatas. Sistem Informasi Geografis merupakan sistem komputer yang dapat merekam, menyimpan,  menulis, menganalisis dan menampilkan data geografis. Dengan menggunakan metode Waterfall maka rancangan s...

The use of information technology has a very broad scope. One of them is in the field of funeral. Funeral is often a "backward" issue in this life. Even if we look at our "nature" as human beings, we will all experience what is called death. The thing we need to prepare for death besides worship is that we need to prepare our final rest right. We often forget this, even though if we see the phenomenon that the world mortality rate is increasing every day, even Indonesia is one of the countries with a very high mortality rate. The high mortality rate is not in line with the number of locations or burial places available. This has become a problem that must be solved and become a problem that is quite serious and needs serious handling. One of the solutions to this problem is the use of information technology to record the overall mortality rate and also record the availability of existing locations to bury it. That way the government can monitor every problem that exists and can provide solutions that can be disseminated easily by utilizing information technology, the author uses the Waterfall method to facilitate the process of needs analysis until testing the design of building information systems public cemetery (TPU) Pondok Rajeg Bogor. PENDAHULUAN Pada era globalisasi seperti saat ini, perkembangan teknologi semakin hari menunjukan peningkatan yang sangat pesat. Perkembangan tersebut dipicu karena semakin besarnya kebutuhan akan teknologi untuk membantu dalam menjalankan kehidupan sehari-hari. Perkembangan teknologi kini telah meyentuh berbagai kalangan masyarakat didunia. Baik dewasa, remaja maupun anak-anak telah mengenal teknologi. Bahkan tanpa disadari ketika mengawali aktivitas, dimulai dipagi hari hingga malam hari setiap manusia bersentuhan dengan teknologi baik secara langsung maupun secara tidak langsung. Dewasa ini peran teknologi telah mnggantikan peran manusia dalam menjalankan kehidupanya. Perkembangan teknologi yang sangat terasa saat ini adalah perkembangan teknologi pada bidang informasi. "Internet", kata tersebut akhir-akhir ini menjadi salah satu "penyebab" utama yang "mengakibatkan" seluruh orang dunia dapat berinteraksi dengan mudahnya. Jangkauannya yang tidak terbatas menjadikan masyarakat "berbondong-bondong" untuk mengenal dan mempelajari penggunaannya. Karena dengan penggunaan internet kita dapat bertukar informasi dengan sangat mudah dan dalam waktu yang sangat cepat. Pemanfaatan teknologi informasi memiliki cangkupan yang sangat luas,. Salah satunya adalah dalam bidang pemakaman. Pemakaman sering menjadi isu "terbelakang" dalam kehidupan ini. Padahal jika kita melihat "kodrat" kita sebagai manusia kita semua akan mengalami apa yang dinamakan dengan kematian. Hal yang perlu kita persiapkan menuju kematian selain amal ibadah adalah kita perlu mempersiapkan tepat peristirahatan terakhir kita. Angka kematian yang tinggi tersebut tidak seiring dengan jumlah lokasi atau tempat pemakaman yang tersedia. Menurut Tukiman dalam (Frieyadie & Kristiana, 2016) Ahli waris atau masyarakat tidaklah mengetahui apakah kerabat yang dikubur masih terdata atau tidak, atau memamg sudah ditumpang dengan jenazah yang Hal tersebut menjadi permasalahan yang harus dipecahkan dan menjadi masalah yang cukup serius dan perlu penanganan yang serius pula. Dari rasio yang ada peningkatan jumlah penduduk pada suatu wilayah akan berdampak pada jumlah kematian serta jumlah kebutuhan lahan yang tersedia (Sofian, 2015). Dengan begitu pemerintah dapat memantau setiap permasalahan yang ada dan dapat memberikan solusi yang dapat disebarluaskan dengan mudah

Are there "Best practices" in project management?

"One size fits all" is still in common use, and this approach has proven to lead to project failure. Flexibility, situational intelligence, and creativity are essential to deliver project success. Projects are temporary and unique, and a practice that has been successful in one project may fail in another.

The need to recognize and master ever-changing requirements and environmental conditions is a tough challenge for professional project managers. The same practices that led to success yesterday may cause failure today. Selecting favorable responses to a given situation is often the most critical factor of the dynamics of success and failure. This book is designed to help project professionals assess a situation, predict the appropriate approach, methodology and achieving styles, and then apply them in a situational fashion.

Nowadays, the benefits of using the internet can be felt in society or even in the industrial world, either for business or just for entertainment purposes. Until 2017, Indonesia is one of the countries with the highest internet users globally, with around 112,6 million internet users. On the other hand, many small businesses have not used the internet to advertise their products. This project's main objective is to design and develop a company profile website of CV Rian as one of the brick micro-industry in Nagrek, West Java, enabling people to search and access information easily and quickly. This project uses Waterfall Model as Sofware Development Life Cycle (SDLC), MySQL as the database, and PHP for server-side scripting. The database is used for storing posts, admin data, and images. 

The Ministry of National Education has declared excellence scholarship program, one kind of these excellence scholarships is P3SWOT. P3SWOT is an excellence scholarship given to researcher, writer, creator, artist, journalist, athlete, and figure. As a holder of P3SWOT excellence scholarship, the Secretary of Excellence Scholarship, Bureau Planning and International Cooperation, the Ministry of National Education has been taking the advantage of the information technology by building a website that provides registration information, a registration form that can be downloaded by registrant, and the announcement of the scholarship winners. However, the website is not optimal because it is static. The selection mechanism of P3SWOT excellence scholarship still has some problems. Recently there are ineffective registration and unintegrated scholarship registration data. The online selection of P3SWOT excellence scholarship information system was developed to solve those problems. This information system was developed using Unified Process. Unified Process is an object oriented software development process that consists of five workflows. They are requirement, analysis, design, implementation, and test. This information system was built using PHP 5 programming language and MySQL 5 database management system. This information system can be used to handle the selection of P3SWOT excellence scholarship including registration, registration verification and scoring, deciding the winners, and reporting.
