What is the real meaning of requirements?
They can be defined as the needs of the project for giving the perfect advantages and utility. There are great chances of a project’s failure if the analysis isn’t performed properly or the requirements aren’t clearly defined. It doesn’t matter how accurate the design and concept is, they will be destined to fail if the requirements are not fulfilled.
We all know that there are many functionalities in a system, the same is the case with the requirements. They are also figured out in different forms. The process of analysis become too easier and crystal clear with the help of categorization of requirements for every participating stakeholder.
According to the BABOK, the categorization of requirements is categorized in the following manners:
- Stakeholder Requirements
- Business Requirements
- Transition Requirements
- Solution Requirements
- Functional & Non-Functional Requirements
There are quite chances that you will get confused with a great range of requirements needed to be figured out. You may get puzzled about how to identify these requirements?
The complete process can be visualized by a simple approach and begin the process step by step.
Check out the example mentioned below for completing that process:
When you think about making a dish for someone, you have to take one thing in the account for whom you are cooking that food. Whether you are making it for your friends or family or even kids? Your business requirements will be defined by these things. After finding that thing, you have to find out whether you can drink alcohol with the dish or the children shouldn’t eat spicy ingredients that are stakeholder’s requirements. In addition to that, it is also important that you should also consider the time you needed for making that meal and preparation needed to serve that dish that can be defined as the non-functional requirements. AT last, you can make a delicious Italian dish with some tasty sauce and basil leaves that are technical requirements.
Now, it’s time for understanding all these requirements with the help of the technical examples. Check all these things that we have mentioned below carefully.
They can be defined as the top priority mission, objectives or needs of a company. The document of business requirements generally consists of what kind of features are needed in the object, which kind of market needs to be entered by the business, assessment of the dangers, success measured in terms of business’s view, and many more.
Main Example: Login screen needs to be there so that the users can log into the system.
Hints for identification:
Phrases or words that depict what, like “we require to be able to”, “we require for figuring out this” and “we require a path to”.
User or Stakeholder Requirements
They can be defined as those needs that are always expected by all the stakeholders from the solution that they will receive. It also includes the method to interact with the solution. The complete system is explained by the stakeholders in detail as per their perspective. The problem from the unique perspective can be seen by all the stakeholders. So, it is important to understand all the requirements in detail for making you know about the full system. Each of these requirements should be analyzed in such a way that they never collide with each other.
The customer should be redirected directly to the dashboard as a user for making login successfully as a user.
The user needs to be redirected towards the landing page of the Administrator for login successfully as an admin.
Hints for identification
The tips to identify them is the same as the business requirements, but they need to be from the view of the user. Phrases or words that depict what, like “we require to be able to”, “we require for figuring out this” and “we require a path to”.
They can be defined as the in-depth conditions and the powers that need to be met by the business as well as stakeholder requirements. The main motive behind creating the Software Requirements Specification is capturing both the functional and non-functional requirements. They are categorized into two parts that are mentioned below:
(i) Functional Requirements
The particular behaviors, details, responses, and rules related to the solution are defined by the functional requirements. The following things are addressed by this type of requirements:
- The functional capabilities that are supported by the system. (features)
- The rules related to the data validation and the way they need to be managed. (business rules)
- The level of interaction among the various stakeholders or users within the system. (use cases)
A complete detail about the technique system needs to be developed are included in it.
- The users who have registered should be able to log in successfully with the help of valid username and password.
- After login successfully, the user should be redirected towards the system’s landing page.
- In case of the failure for the not registered username, the username not registered message should be prompted, whereas the invalid credentials should display invalid credentials.
- The new users should be capable to register in the system by tapping on the sign-up option.
- In order to recover the password, the users should be able to successfully tap on the “Forgot Password” option.
(ii) Non-functional Requirements (Quality of Service)
The conditions where the solution will be operated are defined by the non-functional requirements. A solution should have those qualities through which the system can be operated in a smoother manner. Furthermore, it defines standards for security, reliability, accessibility, performance, internationalization, portability, architecture, reliability and all the other related things through which the system gets an assist in the practical world.
- Maintainability: There should be some proper logs that show the operation result along with the timestamp needs to be added to all the forgot password/ login/ signup option.
- Performance: The maximum time taken by the system to redirect the user to the landing page on successful login should be 10 seconds.
- Platform: The login functionality should be set in such a way that it conducted in a similar fashion on several platforms.
Hints for identification:
In order to make the identification process easily among these, the functional requirements should be termed as verbs, whereas the non-functional requirements should be termed as adjectives on these verbs.
Implementation or Transition Requirements
They can be defined as those circumstances or abilities that only demand enabling solution’s transition from creating to the use of real-world business. It will show them what needs to performed with the technology, training, process, education, and enhancements prior to getting transforming from as-is to the to-be.
It doesn’t valid in this instance, but the login system should work similarly the way single sign-on functionality get applied for the explanatory purpose.
Hints for identification
Check out temporary requirements, like “transforming from old system to new system”. There are lots of other kinds of requirements that are utilized throughout the diverse range of systems on the basis of scope, such as:
After clearing the requirements of the solution, the most amazing method for beginning the process with development that includes technology. It can be defined as the bridge for the communication between engineers and analysts. Also, the technical engineers are its creator. The design and its architecture are specified by these requirements for the solutions parts that need to be created and applied. The method by which solution will be programmed, display data and store data will be defined by these requirements.
– Browser Support
The present and most updated versions of Chrome, Internet Explorer, Opera, Edge, and Safari.
Hints for identification
The technical jargon is utilized as the database schema, technical algorithm password encryption algorithm, etc.
User Interface Requirements
It can be defined as the user interface design for the functionalities. The interface requirements are derived from the solution requirements. The user input controls, buttons, links, etc. should be placed on the display for making proper functioning. Wireframes are used for representing them.
- It is important that textboxes for username & password need to be set below the respective labels for username & password.
- The buttons of login & cancel should be located in the center of the display.
- The sign-up option should be situated below the login option.
- The link to forget password link should be located above the login option.
In simple language, the requirements analysis can be defined as the knowledge, identification, and setting all these requirements. It became pretty easy for the department to know and follow the details of the system after categorized requirements.
