1. Identify three criteria you consider to be the most important in a quality system. Briefly discuss your rationale for selecting these criteria.
Answer: Thе extent tо whісh а ѕуѕtеm mееtѕ thе nееdѕ and expectations оf іtѕ uѕеrѕ determines the quality of the system .Comparison with competitors also helps us determine the quality of the system. The major focus of quality management is on refining, defining and measuring the quality of the development process and the product during development of the software.
The three main criteria that are most important in a quality system are as follows:
• Efficiency Criteria: Efficiency means that our software system is fast and provides maximum productivity with minimum wasted resources in order to

While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
If the error is detected during a later stage of software development, The developers will require to do a lot of reverse engineering processes which will be very frustrating and time consuming, the developers will have to review preceding steps and rework their deliverables and also might have to start from scratch. The later the software error is detected the more the number of people will be affected by it. This will in turn result to an increase in the cost required to communicate with the affected people and then fix the error. Thus, the cost for communicating the details of the defect, distributing and applying the software fixes and probably retain and convince the end users to use this particular software that has been sold to hundreds and thousands of customers will be too high. Once the goodwill and the brand value of the software is affected it is difficult to regain the customers trust. Ensuring early fixing of errors will save the developers

A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
A software development methodology defines the activities to be undertaken by each individual in the development process, specific techniques for accomplishing those activities, like using a flowchart to document the program logic of a particular software. It also offers guidelines to manage the quality of software at various stages of development.
Early fixing of errors not only helps save cost but also helps in mitigating the various risks associated with software development and it also helps in improving and monitoring quality of the system etc. It has been proven that the cost to identify and mitigate the errors in the early stages of development of a software will be hundred times less than the cost of removing an error in the software system that has been distributed among hundreds of
Software design and development is a field that requires various skills and abilities. Companies engaged in the development of software should provide an inclusive work environment where the different strengths of their employees are recognised, utilised and respected. Software development involves far more than programming skills. Personnel are required with strong communication, teamwork, attention to detail, creativity, design and problem-solving skills. Different personnel will possess these skills in varying proportions. It is the job of management to foster and encourage the development and enhancement of skills in the workplace.
quality we can predicate from it. The systems that fail are those who rely on
For this assignment, I have decided to focus on what makes a good quality
No matter where you work , schools , university , hospital , software house all they rely on a one specific thing by which they can judge their progress by getting feedbacks of the peoples. The thing is QUALITY, the most important weapon in any organization to optimize the product.
1.0 IntroductionIn this report I will be concentrating on the failure of software systems. To understand why software systems fail we need to understand what are software systems. Software systems are a type of information system. This is because a software system is basically a means for hardware to process information. Flynn’s definition of an information system is:"An information system provides procedures to record and make available information, concerning part of an organization, to assist organization-related activities."Humans have been processing information manually for thousands of years, but with the vast increase of demand for knowledge this century has meant that a new method of information processing has been needed. Software systems have provided a new means that is much faster and efficient.
To increase software quality, developers must thoroughly test their code early in the development process. Bugs must be caught and r...
Insightfully mapping out the technological advancements in software development from its beginnings somewhere in the late 1940’s to the current modern age. There is more than enough compelling evidence that software technology has laid a strong impact on all economic and social aspects of our modern day living. Thus, a systematic approach towards high quality software development is required due to an increasingly quality oriented market and competitive business world.
Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change.
Evaluate solutions on the basis of quality, acceptability, and standards: solutions should be judged on two major criteria: how good they are, and how acceptable they will be to those who have to implement them.
Quality is the primary idea for majority of managers and leaders across the world, and the use of tools implemented by great guru like Deming, Juran and Crosby and widely used as well as those instituted by organization of standardization such ISO or PMI have made the face of quality the number one element of comparison among competitors. The quality philosophy is to be implemented at different point within the company depending of the philosophy used, from Deming to Juran and Crosby points about quality are divergent and they also have some common point to share.
There is many software development methodologies exist that is used to control the process of developing a software system. No exact system was found which could help the software engineers for selection of best software development methodology. This paper present the framework of expert system combined with Likert scale. With the help of Likert scale we create a rule based model and assign some weighted score to each methodology and develop a tool named as ModSet which will help the software engineers to select an appropriate development methodology that may increase the probability of system success.
Every organization has unique reasons for automating software quality activities, but several reasons are common across industries.
Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing.
Quality is a word which has been used for a very long time, lots of books have been written about it, and many of the world's scientists have defined it in many different ways. In this research paper, I will emphasise the Quality Management System, why is it important? What is it used for? What is the importance of having a Quality Management System? Many people think implementing QMS costs a lot and all the benefit is a piece of paper which says that your company is certified in having QMS.
