The maintenance of applications is a crucial activity in the software industry. The high cost of this process is due to the effort invested on software comprehension since, in most of cases, there is no up-to Authors: Luis F.
Software development is the process of conceiving, specifying, designing, programming , documenting , testing , and bug fixing involved in creating and maintaining applications , frameworks , or other software components. Software development is a process of writing and maintaining the source code , but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Embedded software development , that is, the development of embedded software , such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself, and is often developed separately. The need for better quality control of the software development process has given rise to the discipline of software engineering , which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development. There are many approaches to software project management , known as software development life cycle models, methodologies, processes, or models.

Two major rules of this method Programs were to be broken into functions and subroutines There was only a single entry point and a single exit point for any function or routine. Software development starts by working with users and other stakeholders to determine what the software needs to do.
Software engineering is the systematic application of engineering approaches to the development of software. When the first digital computers appeared in the early s,  the instructions to make them operate were wired into the machine. Practitioners quickly realized that this design was not flexible and came up with the "stored program architecture" or von Neumann architecture. Thus the division between "hardware" and "software" began with abstraction being used to deal with the complexity of computing. Programming languages started to appear in the early s  and this was also another major step in abstraction. David Parnas introduced the key concept of modularity and information hiding in  to help programmers deal with the ever-increasing complexity of software systems.
The waterfall model is a breakdown of project activities into linear sequential phases, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. In software development , it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction "downwards" like a waterfall through the phases of conception, initiation, analysis , design , construction , testing , deployment and maintenance [ citation needed ]. The waterfall development model originated in the manufacturing and construction industries; where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in the development process [ citation needed ]. When first adopted for software development, there were no recognised alternatives for knowledge-based creative work. The first known presentation describing use of such phases in software engineering was held by Herbert D. In the paper was republished with a foreword by Benington explaining that the phases were on purpose organised according to the specialisation of tasks, and pointing out that the process was not in fact performed in a strict top-down fashion, but depended on a prototype.

Being an integral part of software engineering processes along with the business analysis and requirement specification, design, programming and testing, the project management has been a topic of considerable debate for years. In fact, the organizations using proven project management practices waste 28 less money and implement projects that are 2. Project management professionals conclude that the definition of a successful project is one that is not only completed on time and within budget, but one that also delivers expected benefits. Regardless of the scope, any project should follow a sequence of actions to be controlled and managed.
requirements emphasize rigorous documentation and well documented design and testing. • SCRUM - is currently the most popular.
How do the top software development methodologies waterfall, rapid application, agile, and DevOps work? And which method is best for your project? Successful projects are managed well.
Software Testing Methodology is defined as strategies and testing types used to certify that the Application Under Test meets client expectations. Test Methodologies include functional and non-functional testing to validate the AUT. Each testing methodology has a defined test objective, test strategy, and deliverables.
