In order to avoid receiving a product that is unreliable, slow, and insecure when acquiring custom software, you and your development team must agree on its specifications. There are two types of requirements in the domain of software development: Functional and Non-functional requirements. Continue reading to learn the difference between the two and why they’re so important to the success of your project.

Functional Requirements

Functional requirements define what a software system should do, as well as its features and functions. It specifies a module’s or a system’s function.

Functionality is determined by comparing a set of inputs to the system under test to the system’s output. Functional requirements thereby describe a certain system outcome when a task is carried out on them by the user.

• For example, “Send email when a new customer registers up” or “Open a new account” are functional requirements that specify a specific behavior or function of the system when certain conditions are met.
• A user must be verified when they attempt to log in to the system.
• A verification email is sent to the user once they first register on a software system.
• In the event of a cyber-attack, the system will be shut down.

Types of Functional Requirements

The following are the types of functional requirements:

Business regulations

What are your goals for your system? What qualities are necessary for achieving your objectives?

For each function within the system, each system activity must be defined and all functional requirements types must be taken into account. As a result, this section will likely be the longest of all the others because so many needs may fit under this category.

Corrections, changes, and cancellations of transactions

These specifications look at each transaction’s insertion, modification, deletion, cancellation, and error checking.

Functions of authentication

They have to do with the data users divulge to the system and the amount of authentication they utilize.

Levels of authorization

These operations choose who can CRUD (alter, read, update, or delete) information and various system access levels.

Audit Monitoring

The technique of tracking crucial data is known as audit tracking.

External connections

These operations deal with the external connections between systems that are not the primary system.

Certification Requirements

Your company may require qualifications such as security certificates to work on the system.

Requirements for searching/reporting

How users can search for and obtain data is described in this area of the requirements.

Historical Data

If your database is dynamic, you will experience an increase in data, thus you must specify the amount of storage you need to handle this expansion.

Archiving

The projects must have the ability to archive the data for long-term storage because your system’s data may increase faster than your storage space can accommodate.

Requirements for compliance with the law or regulations

The organizations and their systems are required to abide by laws, government regulations, and even internal policies.

Algorithms

Algorithms are used to automate any necessary calculations or data element manipulations.

Database

The components and formats you ought to apply when deciding what data a system needs to store.

Backup and restoration

This feature will be necessary if your machine crashes and all of your data is lost.

Here are the pros and cons of creating a typical functional requirements document

• It enables you to check if the application contains each of the characteristics specified in the functional requirements.
• You can define a system’s or one of its subsystem’s functionality with the help of a functional requirements document.
• The missing needs are easier to find when the functional requirements are combined with the requirements analysis. They help to define the intended system behavior and services explicitly.
• Bugs found during the functional requirements capture phase are significantly simpler to fix.
• Support for objectives, jobs, or user activities.

Non-functional Requirements

Instead of specifying “what a system should do,” the Non-functional requirements talk about “what a system should be” (functional requirements). Non-functional requirements describe a system’s general properties. They are also referring to as quality characteristics. 

The majority of them are created from functional requirements that are based on feedback from customers and other stakeholders. The Non-functional requirement focuses more on overall system behavior than on a specific function.

• For example “A database should update modified data for all users accessing it in under two seconds.”
• Emails must be sent with a maximum latency of 12 hours.
• It should take 10 seconds to process each request.
• The website should load in three seconds even when there are more visitors at once.

Types of Non-functional requirements

The following are the types of Non-functional requirements:

Capacity, the present, and the future

Inventory forecasting, also known as demand planning, is the practice of predicting required inventory levels for a future period using past data, trends, and known upcoming events.
