Advantages of developing software in which quality is good enough

The main purpose is to develop , operate and maintain a software product efficiently. The quality of any product is built into it at the designing phase. The specifications of a product are prepared and these specifications are the quality features of a product. A manufacture checks the quality of its product against the approved in-house specifications. A product which meets the consumer requirements is a quality product.

Product quality is the way a product performs. While service quality is how well an experience was when shopping for, buying, using a product or service. You can assure the quality of a product by monitoring of the standards. Software QA quality assurance engineers are individuals who monitor every phase of the software development process so as to ensure design quality, making sure that the software adheres to the standards set by the development company. Sometimes software quality assurance engineers are confused with software testers, which is a mistake.

Software testers test parts of the software at different stages of development, whereas a software quality assurance engineer oversees the entire development process, which includes software testing, from start to finish. The monetary success of the software product is largely due in part to the quality of the product as well as the product's ability to hit the market on time. Both are the responsibility of the software quality assurance engineer. Quality is not an attribute of the object or product, it is a perception that relates a person observing or using a product to that product.

Hence, quality is not absolute, but relative. In the lifecycle of a product, quality might be different along the stages. A new product could be a 'quality' product if it is chock full of bells and whistles, while later in life dependability and reliability are perhaps a better description of what is 'quality'. This makes quality hard to define: Subjective and evolving. A good quality product can be found in low price as and a bad quality product can be branded and expensive.

Quality of Process is more important to keep the Quality of the Product. Quality process works to clarify the business objectives and plan possible development path. This helps to consider the place of the product and services in current and future market situations. I wouldn't say that either is more important than the other being both are important to business success.

What I will say is what should come first. The Waterfall and Lean models are as different as a mole and a gazelle. And since Lean and Waterfall differ with interim steps and pace of the project — the same goes for Agile vs. From industry experience, all the software development methodologies are more functional with certain project types. Different types of complexities will demand different experts and level of experience in the method of choice. Considering that no method is a hundred percent perfect, developers must analyze all the pros and cons.

Another set of factors to consider with great importance are budget, project scope, available resources, time frame, and preference. Contact us today and kick-start your custom development with capable project managers, and a team of developers with resonating skills, and experience.

One is the data accuracy and the second is metrics selection. All metrics will not be suitable for all processes and projects. So the selection of the metrics needs to be done carefully.

Let us now look at some very important and most commonly used Software Quality Metrics and how they are helpful in driving a better code. The first measure of the quality of any products is the number of defects found and fixed. The more the number of defects found, would be the quality of development is poor. So the management should strive hard to improve development and do an RCA Root Cause Analysis to find why the quality is taking the hit. This is an important metric for assessing the effectiveness of a testing team.

DRE is an indicator of the number of defects the tester or the testing team was able to remove from going into a production environment. As the name suggests it is the average time between two failures in a system.

Based on the AUT and expectation of business the definition of failure may vary. For any online website or mobile application crash or disconnection with the database could be the expected failure. No team can produce software that never breaks or fails, so the onus is always to increase the MTBF as much as possible, which means that in a time frame the number of times the applications fail should be reduced to an acceptable number.

This again is quite self-explanatory. The mean time to recover is basically the time it takes for the developers to find a critical issue with the system, fix it and push the fix patch to production. Hence the average time which the team needs to fix an issue in production. Important metrics especially for mobile apps and online websites. It is a measure of how often the mobile app or website crashes in any environment. It is an indicator of the quality of the code.

The better the code, the longer it will be able to sustain without crashing. In recent times where the speed of delivery has taken utmost importance, the traditional methods life the SDLC and waterfall models have taken a backseat, giving way for more dynamic and fast-paced agile, scrum and lean methodologies. This section on software quality metrics would be obsolete and incomplete if we do not look at some very important metrics in agile.

Lead time is defined as the time it takes from the time of project or sprint kick-off to the completion. In an agile process, we normally pick up user stories that will be delivered at the end of the sprint.

The lead time is thus defined as the time it takes to complete and deliver these user stories. The project can easily get taken off track if the customer representative is not clear what final outcome that they want.

Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers unless combined with experienced resources. DevOps Methodology DevOps is a popular term gaining a lot of attention among all the software development methodologies because of the unconditional benefits it offers to its customers.

Advantages of DevOps Faster Process Multiple ongoing processes work simultaneously which makes the process faster and easier for businesses to process on time. By adapting to changes in the market, DevOps enables businesses to grow efficiently and drive definite business results. Offers Rapid Deliveries Microservices and Continuous delivery are some elements of DevOps that offer business continuity and recent updates rapidly.

DevOps allows businesses to continuously innovate and improve products for a better software product. Reliability With increasing changes in the product and infrastructure, the developed products are robust and secure with a competitive advantage against all the peers.

Collaboration This is a collaborative platform pillared on strong parameters of accountability and ownership. Both the development teams and operations team are in sync with all activities of the development lifecycle to deliver faster and effective products. Disadvantages of Devops DevOps demands Cultural change Yes, this is true if you adopt DevOps in your business, it demands cultural change and business needs to restart their processes in order to grow efficiently.

Organizational Upgradation is another important factor for companies to upgrade their business from conventional methods to dividing into multidisciplinary tasks that will allow them to use multiple skills at the same time.

Speed and security is not something that is achieved all the time using DevOps. For some critical software engineering projects, there are companies that may not assure both in a single stage and you may need to consider a separate plan for security at every stage of your DevOps workflow.

Advantages of Scrum Development Use Scrum Development for fast-moving, cutting-edge developments, rapid codes, and testing mistakes that can be easily rectified. In this methodology, decision-making is entirely in the hands of the teams.

This methodology enables projects with the business requirements documentation and other signs that contribute to success. Enterprises can control the Project development steps visible in this method with emphasis on frequent updating of the progress. A daily meeting easily helps the developer to make it possible to measure individual productivity.

This leads to the improvement in the productivity of each of the team members. Due to short sprints and constant feedback, it becomes easier to cope with the changes. It is easier to deliver a quality product at a scheduled time.

Disadvantages of Scrum Development As one of the leading causes of scope creep is Agile Scrum thus there is no definite end date, the project management stakeholders will be tempted to keep demanding that new functionality be delivered.

You should keep the estimation of project costs and time accurate if not then this kind of development model will suffer. It is good for small, fast-moving projects but not suitable for large complex projects.

This methodology needs experienced team members only. If the team consists of people who are novices, the project cannot be completed within an exact time frame. Scrum works well for project management when the Scrum Master trusts the team they are managing. If they practice too strict control over the team members, it can be extremely frustrating for them, leading to demoralization and the failure of the project.
