Problems in RAD (Rapid Application Development)

Innovative ideas are necessary for any application development. When we planned for any application, we need to think its problem (i.e. what kind of problem can be occurred) also & when problem occurred then there must a solution for that problem.

The same rules applied for RAD (Rapid Application Development) too. Let see what kind of problem can be occurred:

Problems

In 1970’s when processes developed, for instance the Waterfall development methodology, repeatedly resulted in the development of applications that did not meet up client needs as applications take so long to make that requirements had changed before the system was complete. As a result, for bigger projects, these methodologies often resulted in complete, except unfeasible, system.

The reason of the crisis was recognized in the strict devotion to completion of one lifecycle stage before touching on to the next lifecycle stage. Particularly, building an application based on necessities that have been frozen at a point in time means that the longer development take, the more possible that industry needs will transform and overthrow the necessities that the system being developed is based upon.

In my next post I’ll discuss little bit of solutions of these problems.

Brief history of RAD (Rapid Application Development)

In my previous post, outline of RAD (Rapid Application Development) was discussed. In this post I elaborate little bit about the history of RAD and Problems of RAD. I’ll discuss the solutions and Pros and Cons of RAD on my next post.

History of RAD

Rapid Application development refers to the growing of programming applications and differs from programming itself in that it has a higher level of dependability, including for necessity capturing and testing. Rapid Application Development was a response to non-agile processes developed in the 1970s, for example the Waterfall model. The difficulty with earlier methodologies was that application takes so time-consuming to construct that necessities had changed before the scheme was full, often resultant in impractical systems. Initial with the thoughts of Brian Gallagher, Scott Shultz & Barry Boehm, James Martin developed the Rapid Application Development shift toward during the 1980s at IBM and finally formalized it by publishing a book in 1991.

Rapid Application Development (RAD) has been in survival for nearly 20 years, but is as suitable these days as it was when it was primarily conceptualized.

Introduction to RAD (Rapid Application Development) Methodology

Now we start posting on rapid application development (RAD). Well it’s started on the early 90’s. It is an advertising catchphrase that about every software development tool uses, yet one that seldom applies. At a high level it is a Custom Application Development method that uses:

§ Iterations in System Development Life Cycle

§ The Prototyping Approach to Development

§ CASE Approach to Development

Look on the outline of RAD (Rapid Application Development)

Outline

Rapid Application Development (RAD) is a software development methodology that focuses on building software applications in a very short amount of time; conventionally with compromise in usability, skin and/or implementation speed. The term has recently turn out to be an advertising catchphrase that generally describe applications that can be designed and developed within 45-90 days, but it was initially planned to describe a procedure of application development that involves application prototyping and iterative development.

This is the only outline of Rapid Application Development, in my next blogs there’ll be some history of RAD.

software development requirement analysis

Now it’s a time to write about software development requirement analysis.

Software Development Requirement analysis is a clear step in the software development life cycle (SDLC) replica. Since insufficient awareness to requirements is a key reason of software defects, getting software requirements without a doubt defined in the beginning saves time, cost, and irritation in later on phases. This way details the procedure of seminal requirements. Topics consist of definitions and levels of requirements, common system and advantageous characteristics of requirements, risks connected with requirements, requirement analysis methods as well as sources, necessities roadmap, justification and traceability of necessities, and requirement transform administration.

Theoretically, requirements analysis includes three types of action:

Eliciting requirements: the job of communicating with clientele and users to conclude what their necessities are.

Analyzing requirements: shaping whether the stated necessities are undecided, imperfect, vague, or conflicting, and after that resolve these issues.

Recording requirements: necessities may perhaps be documented in different forms, for example natural-language credentials, use case studies, or procedure condition.

Software development requirement analysis Introduction

In my previous post, I posted some basic concepts of Software development and Iterative software lifecycle methodology.

Now its time to elaborate little bit about custom software development requirement analysis which is the most crucial part of any application development. This is the base of any software, i.e. if you don’t understand your requirement it creates major problem in later stage. Sometime after completion of a project, it comes to know that we skip these features like that kind of things; it causes to back and redesign the whole process again. And of course cost of the project increase, unreliable and time also increased.
Now question arise, how can we avoid this mishap or uncertainty in software development? Answer is simple; we need proper documents of requirement analysis. Remember, requirement analysis is critical to the success of any application projects.
Next blog I’ll post all about requirement analysis.

Information about Iterative Software Development Lifecycle Methodology

So before writing Iterative software development lifecycle methodology, let’s have a look on software development…

Now question arise what is software development? Now this kind of question put up what are the basic needs of software development? How we develop software? What are the basic requirements to develop software?

Here I only give brief information of software development rather than answering all the questions what I put up?

Software development is the version of a user require or advertising goal into a software product. Software development may consist of new development, re-development, change, reprocess, continuance, or any other activities that effect in software products. A software development procedure is a procedure used to build up PC software. It may be an informal process, devise by the group for one assignment, but the term often refers to a standardized, accepted method which has been used before on similar projects or one which is used routinely within an organization.

Now, it’s is enough information about software development and its process.
Let’s move on to Iterative software Development Life Cycle Methodology.
Running complex software development project is concerning well-organized operation of assets, risk management and Control, precise cost estimation of budgets and timelines, skilled variety of suitable technologies, and scheduling quality development to congregate time-to-market necessities. Risk assessment is a truth in every project; Data Solution Inc.’s iterative method designed for software development is purposely to lessen risk.
Any Software Development Life Cycle (SDLC) is comprised of four facets:

1. Requirements Analysis: What are the main features, will the product encompass?
2. Designing: How will the product recommend these main features?
3. Coding & Testing: How will the features be coded and unit & integrated tested?
4. Delivery & Maintenance: How will the product be tested and deliver to clientele?
   

By an Iterative Software Development life Cycle model, the four facets of a software product are included so that business objectives compel the complete process, and the necessities and plan are constantly polished while the code evolves. The project plan arranges the growth into small releases, and mandates ongoing amalgamation of all coded components, incremental build, and cyclic validation of developed requirements and plan. By means of doing so, it encourages a common possession of the product with business analysts, software designer, architect, programmers and software testers; this common ownership reduces the threat of miscommunication and discrepancy. It also enables ongoing modification and addition to keep away from any unlikable surprises just ahead of the deliverance date.
