12 Best Software Development Methodologies with Pros & Cons

Today we have reached a situation where you have control over everything atthe tip of your fingers. Technology has developed beyond imagination. Allthanks to the software development industry!The world of software development is something that is limitless.In fact, the methodology meant for a software development life cycle isactually a structure used for planning and controlling the procedure ofcreating a specialized information system to achieve the desired goals.These innovative methods highlight the process of building software at everystage of development. In fact, this incremental development is more related toproject management and as such does not involve the use of any technicalities.This is more about proper planning and includes any iteration required for thepurpose of highly building highly scalable software.The simple tenacity of these principles is to offer customized softwaredevelopment as per the requirements and something which every softwaredevelopment team should adopt.

Agile Software Development Methodology:

As an innovative approach and one of the leading software development models,the agile software development methodology is used for articulating a well-organized project management procedure allowing for recurrent alterations.Certainly, Agile development methodology is one theoretical outline forundertaking several software products and projects.Another good thing about it is that it minimizes peril by creating software inshort time boxes, known as iterations, which happen to last from one week toone month.

BI for Software Development

The term BI and the use of data-driven management is a not a new concept.However, in the past, much of the data needed for software developmentdecision making was either missing or managers couldn’t use it well. Inaddition, there might have been less motivation to use BI since “seat-of-the-pants” management styles were still popular. However, high failure rates ofsoftware development projects (up to a 70 percent failure rate) has drivenprojects to change. This is where agile and continuous integration conceptscome into play. Software development organizations that realize things need tobe done differently, are usually early adopters of automation, analytics, andusing modern practices such as agile development.The challenge with modern approaches such as agile and continuous integrationis that you loose sight on what aspects of your code base are changing when.The development teams get more autonomy, and that has proven to be a greatmotivator and deliver great benefits, but management teams still need tounderstand what the state of these software is. This is where BI, datacollection and analytics come in. It provides the management team the data tosteer agile development and continuous integration. A particular importantexample of this is testing, which is somewhat of a bugbear for iterativeprocesses since it’s difficult to test just enough parts of a system to ensurenew functions work and no new bugs are introduced. In most cases, developmentteams end up testing much more than they need and slowing down the process. BIcan help here by showing exactly what has changed build-by-build (where testsare needed) and indicate areas of risk, for example, complexity, bad “codesmells”, or static analysis warnings. The collection of data, comparisons,metrics, and static analysis reports on a build basis is a key enablingcapability that has made BI useful for modern development processes.

6 Common Software Development and Testing Challenges in the Financial Sector

Software solutions are increasingly becoming useful in the financial sector ascustomer expectations continue to rise.As of 2018, online platforms and mobile applications facilitate more than halfof all financial transactions. As these numbers continue to rise, there is aneed for effective software solutions in those transactions. There are alsocertain factors that push back the development and testing of these solutions.

Agile Development and Testing

Software developers are finding a hard time adjusting to the agile developmentand testing advancement. This advancement allows them to continuously makechanges to the existing code by rewriting or adding it. As they rewrite or addnew code, fragmentation issues may arise. The developers find it difficult tofrequently run tests on every new added or rewritten code. It is time for themto automate their software testing activities for them to easily identifyerrors in their code.

The Agile Software Development Method Uses an Iterative and Team-Based

ApproachOne main difference between the traditional and agile methodologies is thesequence of the phases in which the software development project is completed.The traditional method uses a linear approach, where the stages of thesoftware development process must be completed in a sequential order. Thismeans that a stage must be completed before the next one begins.These stages usually comprise the following: 1. Requirements gathering and documentation 2. System design 3. Code and unit testing 4. System testing 5. User acceptance testing 6. Bug fixes 7. Product deliveryOn the other hand, the agile methodology uses an iterative and team-basedapproach. Its main objective is to quickly deliver the application withcomplete and functional components. Instead of completing the softwaredevelopment tasks in sequence, they are completed in sprints that run fromaround one to four weeks and where a list of deliverables is completed in eachsprint.The tasks that do not get completed within the sprint are then reprioritizedand included in future sprints. This also means that the different stages ofthe software development life cycle can be revisited as needed.> You may also like: 3 Styles of Agile: Iterative, Incremental, and> EvolutionaryThe typical agile approach involves the following stages: 1. Project initiation 2. Sprint planning 3. DemosWith the traditional method, the details of the entire project have beenvisualized and defined before the project starts. In contrast, the agilemethodology allows for more flexibility in that changes can more easily bemade even after the project starts.It is best employed if the scope of the project cannot be clearly defined inadvance. This also means that making unplanned software development changeswith the traditional method is costlier than with agile.

Software testing levels

Levels in software testing are the different stages of the softwaredevelopment life cycle where testing can be conducted and implemented.Bringing your software to test early on in the software development lifecyclecan ensure that your product performs better as it will be well tested.Software testing levels include:Unit testing involves testing the smallest testable portion of software whichcan be compiled, linked, loaded and tested individually. This test isperformed by developers to ensure that each part of the software performs asintended.Integration testing involves testing the flow of data from one component ofthe system to another. This test checks if various modules of the softwareperform as intended when tested as a group. This test level also validates ifthe software is ready for system testing.This testing level involves testing the entire system to see if it behaves asintended and meets the requirement specification.Acceptance testing involves testing the software against the deliveryspecification of the system to ensure that everything works as intended forthe end-user.Ensuring high quality is the first step that you will take towards building asuccessful mobile app. Although the terms and procedures listed in thisarticle may seem daunting for a first-timer, with a world-class developmentpartner such as Volumetree, you can concentrate on bringing your idea to themasses – we will take care of the nitty-gritty.

Agile is one of the most effective software development methodologies. It’sideal if you want to stay updated about the phases of development and remainin contact with the team on regular basis via meetings and artifacts.

Benefits of Offshore Software Development Services

Outsourcing a remote team of developers is much cost-efficient than hiring anin-house team and as per rough estimates, a remote developer will cost you 34%less than your local developer. That’s because mostly the offshore developmentcompanies and freelance software developers are from developing countries likeIndia, Ukraine, Indonesia, etc and therefore they’d cost you much less thanyour local developer. For example, the average cost of IT outsourcing in Indiais $18-50 / hour, whereas you’ll have to pay $25 – 250 / hour for the similarservice in UK and USA. This is a great cost-saving option for start-ups whoare already running low on budget.Innovation and quality are the USP of offshore companies; they have teams ofhighly qualified professionals who are proficient in meeting your requirementsand ensuring top-notch final product. Training young professionals and makingthem as productive as an offshore developer is will be time-consuming orbudget-consuming if you’re aiming to hire a senior professional.Outsourcing gives you an opportunity to hire the best pool of developers fromacross the globe. Within your limited price range you can get the bestexperienced and certified developers who are ready to develop the product justin line with your demands.When you are dealing with offshore developers, there are great chances thatthey will be living in an entirely different time zone and naturally will havedifferent working hours; this difference in local and remote working hours canbe utilized to ensure 24/7 development cycle. The difference in local times ofdifferent developers residing in different corners of the globe will aid incompleting your project in the least possible time. *

1. Agile Software Development Methodology

Agile Software Development is an approach that is used to design a disciplinedsoftware management process which also allows some frequent alteration in thedevelopment project. This is a type of software development methodology thatis one conceptual framework for undertaking various software engineeringprojects. It is used to minimize risk by developing software in short timeboxes which are called iterations that generally last for one week to onemonth.

The Agile software development cycle

The Agile software development cycle can be broken down into six steps:concept, inception, iteration/construction, release, production andretirement.The first step, concept, involves the identification of business opportunitiesin each potential project as well as an estimation of the time and work thatwill be required to complete the project. This information can then be used toprioritize projects and discern which ones are worth pursuing based ontechnical and economic feasibility.During the second step, inception, team members are identified, funding isestablished and the initial requirements are discussed with the customer. Atimeline should also be created that outlines the various responsibilities ofteams and clearly defines when work is expected to be completed for eachsprint. A sprint is a set period of time during which specific work has to becompleted and made ready for review.A visualization of the Agile software development cycleThe third step, iteration/construction, is when teams start creating workingsoftware based on requirements and continuous feedback. The Agile softwaredevelopment cycle relies on iterations — or single development cycles — thatbuild upon each other and lead into the next step of the overall developmentprocess until the project is completed. Each iteration typically lasts betweentwo to four weeks, with a set completion date. The goal is to have a workingproduct to launch at the end of each iteration.Multiple iterations occur throughout the development cycle and they eachpossess their own workflow. A typical iteration flow consists of: * defining requirements based on the product backlog, sprint backlog and customer and stakeholder feedback; * developing software based on the set requirements; * conducting quality assurance testing, internal and external training and documentation; * delivering and integrating the working product into production; and * gathering customer and stakeholder feedback on the iteration in order to define new requirements for the next sprint.The fourth step, release, involves final quality assurance testing, resolutionof any remaining defects, finalization of the system and user documentationand, at the end, release of the final iteration into production.After the release, the fifth step, production, focuses on the ongoing supportnecessary to maintain the software. The development teams must keep thesoftware running smoothly while also teaching users exactly how to use it. Theproduction phase continues until the support has ended or the product isplanned for retirement.The final step, retirement, incorporates all end-of-life activities, such asnotifying customers and final Migration. The system release must be removedfrom production. This is usually done when a system needs to be replaced by anew release or if the system becomes outdated, unnecessary or starts to goagainst the business model.Throughout the Agile cycle, different features can be added to the productbacklog, but the entire process should consist of repeating each step over andover until every item in the backlog has been satisfied. This makes the Agilecycle more of a loop than a linear process. At any time, an enterprise canhave multiple projects occurring simultaneously with iterations that arelogged on different product lines and a variety of internal and externalcustomers providing different business needs.”
