Top 5 Requirements Elicitation Techniques

Top 5 Requirements Elicitation Techniques

In a software development scenario, solid elicitation abilities are a must have for everyone indicted with essential necessities for their venture or an assignment. Accomplishment is reliant on a combination of practical abilities and social abilities. Working professionals must be able to gauge which method to use and by what method can it be used apart from building associations and attaining accord. They are definitely required while meeting with your stakeholders, for various workshops, conference sessions or in one-on-one sessions too. To leave an effect you must be able to choose and implement methods, which, in turn would be able to perfectly and proficiently recognize the requirements of your business yielding desired results. With emerging and new techniques every day, it is compulsory to become conversant with the important elicitation abilities for describing, documenting, and analysing business requirements. For sure, requirements document is an experimental movement and is considered to be one of the main entities of any software firm. Before moving ahead, let us try to understand the term, elicitation to jot down all the requirements in detail and in a systematic manner.

Some light thrown on the term – elicitation

Elicitation consists of the activities that are taken to understand the consumers and explore their requirements.  Elicitation takes account of the finding and some development, in addition to recording those bits of necessities facts that consumer reps and end users offer to the business specialists.  All in all, it demands duplication.

What is the need of solid elicitation abilities and whys and wherefores mentioned?

From Business Analyst, Enterprise/Business Architect to Data Analyst or IT Business Analyst, they all do their job leading to good transformation in the firm. Either for minor incremental variations or for big variations that have need of a structural shift or social alteration, all these business roles need to collect requirements. This is one of the key functions of all the business roles in a software company. Case in point, all the business people need to pull out and document business transformation necessities from investors throughout the firm. One thing which is pretty clear and is visible too is that business analysis as a career is still growing, as is the exercise of business analysis in a lot of firms across the globe. Practicing new techniques and conversing approaches to describe investor requirements and write whole and full requirements is the key to this role.

Requirements Elicitation

Overview of the main five requirements elicitation techniques

Though there are a plethora of requirements elicitation methods, but there are five key requirements elicitation techniques. On the other hand, all of them are needed at some time or the other, but the most famous ones are the needed the most. Any business professional cannot do without these famous elicitation techniques. So, which one to pick when to get the most from it yielding oodles of benefits? Deciding on the most suitable one depends on a lot of factors, which must be contemplated prior to the selection to get the desired outcomes. The firm’s structural set-up, the strengths of the team members for the project, the environment of your project, the firm’s requirements and likings, all these factors must be taken into account before zeroing on any elicitation technique. Based on these factors decide on the method that works best for your firm and the project.

Cases in point, let us discuss the most famous requirements elicitation techniques that specialists need them at any point of the project development, which in turn will provide a pronounced profit on the venture.

Brainstorming

Brainstorming is an exceptional method of eliciting a lot of innovative notions for a zone of curiosity. Organized brainstorming yields several innovative notions around any particular vital request or area. When the brain is used to storm an imaginative difficulty by audaciously confronting the similar objective, it is brainstorming. It is a method, which supports diversion sort of thoughtfulness. Here, in this case, diversion talks about those team happenings that creates a wide or assorted set of opportunities. With the help of brainstorming, a lot of questions are solved. They are as follows:

• How many choices are obtainable to get an answer to the existing problem just around the corner?
  • What aspects are compelling the group from moving forward with a method or choice?
  • Which factor is delaying the activities involved?
• In what way can the problem be solved by a particular group?

This exercise of Brainstorming emphasizes on an issue or problem, and then offering a lot of fundamental way outs to it. This practice is best useful in a crowd as it appeals on the knowledge and imagination of all participants in the crowd. This really helps in sparking novel ideas to get a perfect solution to the existing problem.

Prototyping

Prototyping is a comparatively current technique for collecting requirements. In this line of attack, you collect introductory requirements for creating a primary type of the explanation — known as a prototype. After the creation of the primary type, it is shown to the customer to get additional requirements. Based on the client’s inputs the application is altered accordingly and then this process is repeated again till the application meets client requirements, business needs and brand essence.

Requirements Workshops

Requirements workshops includes collecting an earlier recognized investors in a planned situation for a definite quantity of time so as to elicit, improve, and/or revise necessities. To get fruitful results, requirements workshops must contain a recorder to record contributors’ effort. As contributors’ may also brainstorm together, they can offer instant reaction to recognized business requirements, which can confirm a firm, effective elicitation of requirements.

Observations

Observation helps the experts in gauging and picking up the useful info that is already present. This plays a key role as all the business analysts or experts is able to document what he or she perceives through many kinds of diagramming and business procedure prototypes along with the use cases. This way an expert is able to make out the exact needs of the business allowing them to use the most comfortable techniques and methods. It is definitely a decent exercise for an analyst to offer summaries from her observations. Also, it allows the analyst to offer an oral narrative of her understanding of the work making sure that there were no confusions of the procedure.

Interviews

In gathering requirements, interviews play a major role.  From one to one to group interviews, they help in gathering information. Ahead of time, you can discuss the business stakeholder’s thoughts, which allows getting his or her viewpoint on the business requirement and the viability of probable explanations. As a result, they are one of the most effective gathering data techniques.

Conclusion

In a nutshell, we have understood that for doing the job effectively at requirements elicitation; brace elicitation abilities to avoid getting your actions off track. You just need to make sure that everyone from the team is involved in the conversation to outline the business requirement before designing the answer for an effective outcome. What is more, make sure that there is a common idea of the necessities so that the necessities can be documented in a combined tactic with the all the project team members. This is suggested for doing an effective job at bringing about the necessities for your business. Make sure that as soon as the elicitation methods get employed, an analyst must document the elicitation swiftly. This is suggested as the discussed ideas are still fresh in her mind. And then the documented elicitation must be shared with suitable shareholders to authorize their arrangement with the results. This step is vital to make sure that the analyst has perfectly grabbed, and stakeholders have precisely conversed, the venture’s requirements. Elicitation functions as the fundamental study to requirements formation stage.

Introduction to Test Driven Development (TDD)

A lot of software’s are made these days and building them on a daily basis can be a pricey affair. As well as, much to your surprise, most of the cost is initiated in looking after the software. With so much efforts and strategies gone into making of the software, this becomes annoying. However, with the advent of Test-driven development (TDD) things are looking easy and viable as its main purpose is to help in cutting down of these runaway costs.

This really helps software developers to concentrate in a better way in building the software, enabling them to build higher quality software. Let us delve into the nitty-gritties of test-driven development, a development practice intended at constructing great quality software. In the first place, you will discover the exact meaning of test-driven development. Later on, we will try to find out that why it exists and its importance.

Let us try to understand and decipher Test-driven Development on a broader horizon.

What is Test-driven development?

Test-driven development is an improvement exercise that helps huge maintenance prices, and allows software makers to construct greater quality software. It has become an integral part of software development stages as it has the potential of solving a lot of current and future problems. In the case of automated tests failure, this improvement exercise trains software developers to compose new code, in turn evading duplication of code. Case in point, the most important objective of Test-driven development is to create the code, which is perfect, simple and devoid of bugs.

Enlightenment about the nitty-gritties involved in Test-driven development

First of all, in the Test-Driven Development process, designing and developing test cases for each and every functions of an application gets started. In general, this is the Test-Driven Development process line of attack. The test cases are developed initially insisting on and authenticating what the code will do. As a matter of fact, the codes are generated primarily and then the test cases. Codes are generated prior to the generation of test cases, as tests might miss the mark if they are established even before the development.

To get the best and desired outcomes, the software development team members develop and refactor the code, without affecting the behaviour of the same. Understanding of the steps involved in Test-Driven Development process is the key to get the desired performance of the software. They should be done the way they are explained, the steps given below outline in what way TDD test must be performed.

• Firstly, add a test
• Then all the tests are allowed to run to check for the failure of a new test case.
• And then the codes are generated.
• Again run the available test cases and refactor code.
• Lastly, the steps explained above are repeated.

This can be well understood with the help of a diagram shown below.

Fig 1: Test-driven development approach

It is all about making use of test-driven development by understanding it thoroughly. And then get the knowledge of making software by means of your understanding of test-driven development abilities, and improve the quality of software.

Is test-driven development that important?

Yes, it is important, at least for all the team members involved during the software development process. It allows the developers to take minor strides while writing software. This practice is productive offering benefits as there is a less chance of getting a broken code. Also, it becomes much easier to carry on in smaller and smaller steps making re-compilation and re-running of the exiting test cases simpler and easier. Also, the traditional methods of testing which are used may not be a perfect fit for huge projects. For huge projects, in the real scenario definitely TDD would be required as it works well for huge systems. As a result, we cannot overlook the advantages which TDD has to offer.

On the other hand, to avail the benefits which test-driven development has to offer, it is extremely important for the involved testers and the business people to act as a team. This is suggested to visualize and discuss the software and its consequences prior to the code creation.

Advantages of test-driven development explained                                                                           

• It definitely allows detecting the bugs too early, if there are any. Though software developers test their code prior to its release, still bugs can arise at any juncture of software development.
• With the help of test-driven development, software developers are able to design the software in a better way with cleaner and more adaptable code.
• It helps to recognize in what way the code will be recycled, resulting in superior software design and more viable code.
• Smaller codes can be written with a solo accountability, allowing the concerned parties to understand it better.
• What is more, test-driven development also powers to write individual code to pass tests centred on consumer necessities.
• Refactoring can be done with ease as proper warning is given if discontinuities are found, which can be fixed prior to the release of the software. This results in a cleaner and clearer code with fewer bugs that can be updated with nominal threats.
• If any team member is not present during the development process, then the new software developers can simply give a lift to the existing code. This knowledge allocation helps the team members to gain a lot of facts, and making the team more operative in doing so.
• It is definitely a boon for software developers as they can spend less time for fixing and developing new features while writing test cases. This helps in making them write cleaner and less complex code.
• Along with writing test cases, interfaces also need to be tested. However, this is not beneficial till you make an effort on a bulk of code where it was not completed. To exercise on a specified part of code it is needed to run the complete system and fix a break-point.
• It boosts trivial strides and mends the design as it makes you amend the needless needs to ease the arrangement.
• It really makes the programmer job easy and simple as they are able to grasp the code really quickly.
• Also, it provides clarity on the requirements as deciphering is needed for an input to be given and on that basis what is the expected output.

The systematic and logical environment of Test-Driven Development confirms much greater attention and high quality code, as the codes are tested, re-tested and fixed. As the tests are conducted from the very start of the software development cycle, period and cash spent in fixing at later phases is reduced. However, there are some disadvantages too. Let’s discuss them one by one.

Disadvantages of test-driven development explained

• To get fruitful results, test-driven development calls for significant expertise, mainly in the initial stages. On the other hand, a lot of systems are not built with unit testing in mind. This makes the separation of components a little difficult.
• In addition to, a lot of software developers lack the expertise to separate and generate fresh code.
• As a matter of fact, every team member needs to generate and keep up the unit tests. This is necessary to keep the tests updated, as, a firm exploring TDD will need to spend time.
• The results of the test-driven development will be good only when methodical test cases are used in tandem with the situations, which are faced by consumers of the end product. It is an advantageous practice and must be adopted by developers. Sometimes extravagant features cause a hurdle in unit testing as simple tests can be created quickly and are easy to manage.
• Generating test cases for fiascos can be monotonous but is it essential as it will offer benefits at the end of the day.
• When refactoring is done initially then the refactoring of test classes also vital.
• Also, each and every team member needs to maintain their test cases to prevent the system from damage.
• Writing test cases need a lot of focus; at times major focus gets shifted to other things resulting in not-so-perfect test cases.
• At the unit level testing, writing test cases is a little daunting.
• It is really tough to work in the same way as you have been working for all these years.

Conclusion              

In a nutshell, TDD, in all probability, is the most essential dynamic in the software development process. However, a lot of persistence is required to master TDD. It can be mastered in combinations, wherein one developer writes the tests and the other pens the execution of those test trial cases. After a while, roles can be reversed to get the feel of the task. The productivity and securities offered by TDD are particularly essential for slim start-ups anticipating making it. With a lot of functional benefits, it is definitely an asset for a software firm.

It is definitely transformative for any software development company, as, in the end a test suite is obtained with a cleaner and clearer code. However, it does not guarantee that it offers cent percent test suite. TDD can be the initial idea for well-organized, understandable code that increases proportionally depending on the requirement. For this very reason, it has been adopted by all the agile developers on a wider spectrum.

Introduction to Behaviour Driven Development (BDD)

Introduction to Behaviour Driven Development (BDD)

A lot of products and applications are launched every now and then these days. When launching a new digital project, some things must be taken care of for a smooth launch. Also, there has to be a connection between the launched product or an application and the prospective clienteles. On the other hand, more often or not a disconnection can arise between the following things which are listed below:

• The software creator is not thoughtful of the requirement of putting up the product or an application.
• The business is not able to define the desired outcomes
• The business’ consideration of the practical trials their requests may offer.

In all these situations, Behaviour Driven Development comes into play as it is able to take care of all these pain points. It can help accomplish all of the above circumstances. At the end of the day, it benefits a business and its technical side provide software that live up to business aims.

To understand it in a better way, let us understand Behaviour Driven Development in a comprehensive manner.

What is Behaviour Driven Development?

Put simply, BDD is a procedure intended to benefit the organization and the supply of software development ventures by refining communication between software creators and business specialists. By this means, BDD makes sure all growth projects continue concentrating on providing what the industry really wants while meeting all necessities of the consumer. Taking everything into account, Behaviour Driven Development (BDD) is a combination and an extension of Test Driven Development (TDD) and Acceptance Test Driven Development (ATDD). In BDD too we compose tests first and the add application code. On the other hand, some differences that are visible are that the tests are written in basic eloquent English style grammar. These written tests are customer concentrated and are clarified as behaviour of application. What is more, instances are used to shed light on necessities.  All these alterations work for the necessity to have a language which can express, in a clear layout.

Necessity of Behaviour-driven development (BDD) framework

In this age of technology and software age, software development is frequently overloaded and a lot of software developers burn the midnight oil to reap benefits and get the desired results. As we all are aware of the simple fact that in software development, it is pretty common to make an effort in attaining aims with the addition of new features to products or applications.

This definitely wastes a lot of time for both engineers and industry specialists. Communication between both sides must be clear to prevent confusion in what the business really wants from its software. Also, at times, business specialists misjudge the skills of their technical line-up. Masked in poor judgment and difficulty, the finished application or a product is frequently technically well-designed. On the other hand, it misses the mark to meet the precise necessities of the business.

The idea needs to be transferred as it is, from business owners or client to the software development. The most common mistake committed by the software teams is that while building a product or an application they start writing down the examples assigned to a single person. However, this is not enough. BDD involves diverse viewpoints and understandings so as to be well-organized. One of the essential notions behind BDD is that no solo individual has the complete solution to the problem. And this is where collaboration of business person, software developer and tester comes into play. Insights from all the three get all the angles covered in line with the software development. Behaviour-driven development (BDD) wishes to modify this as this is a collective procedure. And, BDD definitely addresses all these concerns.

On this note, let us delve into the features to get a clear picture of Behaviour-driven development (BDD).

Features of Behaviour-driven development (BDD) explained

BDD is gaining momentum day by day as it has a number of features to offer which help in offering myriad benefits. Let us discuss the features one by one, they are as follows:

• It definitely shifts the gears from thinking in tests to thinking in behaviour
• It also increases the association between the team members involved in a software development. From testers and software developers to managers and business stakeholders, it enhances the communication between them displaying teamwork with enhanced profits.
• As the language used is universal, it can be easily understood and described.
• The main feature of it is that it is motivated by business value
• What is more, it lengthens Test Driven Development (TDD) and Acceptance Test Driven Development (ATDD) through utilization of natural and universal language that non-technical members can decipher.
• With BDD frameworks available for instance Cucumber, it being an enabler, it turns as a link between business & technical Language, making things easier for everyone.

With so many features it changes the customer notion in to something that truly provides umpteen profits to prospective buyers. All the team members can work as a team offering excellent communication, which is important to their success. In a nutshell, all these features which are present in Behaviour-driven development (BDD help in increasing TDD and ATDD.

And we finish off building a strong and verified product or an application in line with the business requirements. Every line of the creation code, arrangement or even design is openly associated to its specific consequence acquiring business objectives. This is the method BDD makes sure it continuously provides software that matters and is in line with the client requirements and brand essence.With so many features, BDD has its share of downsides too.

Downsides of BDD

Apparently, using examples variation to initiate circumstances so as to provide substantial software is the essence of BDD. However, in case of architecture obstruction, BDD possibly will not be as effective. The best instance for this case is offshore testing, apprehended back by organizational limits when people sit in different offices and are geographically far from one another. This is one such challenge, which is irrational as a lot of firms go for offshore testing. At times the social challenges also occur. This can be well understood with the help of an example.  If by any chance business analysts and testers disconnect over an offshore resource by sending a specification then it does not give results and does not work. At times a software team involving a tester, developer and a business expert discussing the domain, problems and speaking about how they can resolve them, leads to all types of expectations and cut offs.

Conclusion

No matter what is the platform, technology or language, the application or a product is delivered quite often. And, in order to attain success it is necessary and is recommended also that every product or an application needs to be updated and become accustomed to the client needs regularly. Keeping updated is the key as markets and technologies vary. As well, our understanding of business variations and we acquire new prospects on a daily basis. As a result, the way we provide software should echo this continuing procedure of variation.

So as to support the leap of variation, taking on circumstance-based test-driven development is not sufficient. It is recommended that we are able to do radical and quicker variations in the system under the modules. And, this is what BDD is all about. In BDD, we recognize so as to support the knack for systems to vary, so that we are able to securely make huge variations, in addition to the minor ones. Use BDD and adapt to the situation and in turn reap a lot of benefits in line with the brand essence, client needs and business demand.

In the world of software development, it is definitely an in thing and is here to stay as it offers various features along with benefits.
