waterfall methodology go from the top making sure each phases is completed before the next. The waterfall makes sure each requirement is well document and are fixed and if the requirement might change it cannot be used . this is used only when the user know completely what they want. Water fall model makes use of the time control effect where a deadline can be set so the target has to reached. Once a phases is completed and a problem is found the whole cycle has to be restarted. The waterfall has other extensions
1. INTRODUCTION Developing computer software and information systems is a procedure that has been usually worked on by various methodologies of development. Software development methodology is defined as the structure of planning, managing and controlling the process of building up an information system. Officially, the methodology of software development is called Software Development Life Cycle (SDLC), which is used mainly in various engineering and industrial work areas like software engineering
from its early stages of system specification through the maintenance of the system after delivering it. Software engineering as an engineering branch associated with the development of software product using well-defined scientific principles, methods and procedures. The outcome of software engineering is an efficient and reliable software product. When compared to other branches Software engineering as discipline has progressed very far in very short span of time. System Analysis and Design refers
2) Waterfall Process Model Waterfall Process Model or The Classical Life Cycle o was the oldest process model to present a linear framework, describing main phases that are compulsory for a successful software development model. It formed the basis for most software development standards and contains the following stages: Requirements elicitation, Designing, Implementation and Testing. In this model, to begin next stage current stage must be completed. To apply waterfall process model, requirements
8. Software Testing:- It is the major quality control which is used during software development life cycle. The basic function of software testing is to identify errors in the software. During the requirement analysis and the software design phase, the output of a document is usually textual and non-executable. Once the design phase completed successfully then coding phase start, the computer programs are available that can be achieved for testing purposes. It is implies that testing means not
until Henry Gantt designed his chart in 1915. An Information System is a system that is composed of people, computers and the processes that interprets the information. The Information System will reference information and the complementary networks of hardware and software that people and organisations will use to collect, filter, process, create and distribute. It will place an emphasis on defining the boundaries,
3.1 THE PROCESS OF OPERATION MANAGEMENT The systems in operation management of Kamal & Kamal Pest Control have two sections. The first section is core system which means this section have marketing department, Operation department, Customer Relationship Management (CRM) department, purchasing department and Human Resources (HR) department. The second section is the supporting system which the system to support the core. The function of system is all department need to play their roles. If one department
every business and company is profit, by using every method. Businessmen have keen eyes on market, supply chains, demands and methods of production. ‘Targets’ and there completion is very important in every business. Fast tracks to achieve targets is fundamental rule, and CASE is one of them. After introducing CASE three other type of methods also used for same purpose and they are ACG (Automated Code Generation), LDU (Linking Design Utilities) and AADC (Automated Analysis Design
(Project Management Body of Knowledge) 3rd edition, a project is defined as “temporary endeavour with a beginning and an end and it must be used to create a unique product, service or result.” A project is unique in terms that a project is not a regular business operation, a project has a set of activities
developers of those styles of systems to get lightweight software package versions so as to serve this massive market. However, this type of implementations needs formulating a transparent strategy and a operating methodology that may assure meeting the required protocols and achieving success. In developing countries, like South American nation, most of the enterprises are SME
