Functional vs Non-functional Requirements: List & Examples
Precise functional and non-functional requirements are essential to reduce development costs because, when the requirements are clear, the team can develop the project much faster. The difference between functional and non-functional requirements is as follows:
Functional requirements are easy to define because the business idea drives them. They include all the features of your future project and ways users engage with it.
Experience drives Non-functional requirements. In order, to identify them, you need to analyze the product's performance and make it convenient and useful. Such requirements may appear when the product is being used on a regular basis.
In this way, while functional requirements describe what the system does, non-functional requirements describe how the system works.

Defining the “unknown” requirements at the project initiation stage ensures that no opportunity is missed out.
Analyzing the product's functional and non-functional requirements helps you understand what challenges might come in your way.
If you are a product manager, you need to read this blog to understand the difference between functional and non-functional requirements and how you would define each one of them.
The requirements that define how a product responds to the user’s requests are called functional.
On the other hand, the requirements not related to the functional aspect of the software are called non-functional and determine the attributes expected from the system.

Once you have an idea for a future product, the next step in its implementation is to create a list of product requirements.
Mandatory requirements include business requirements, user requirements, functional and non-functional requirements, and implementation requirements.Functional and non-functional requirements are paramount.
The first ones determine how the system should function, what additional software should be integrated, what access levels are set, determine rules for storing and processing data, and much more.On the other hand, non-functional requirements view the system from the user's point of view; they describe the attributes of the system (color, quantity, quality).Each of these two types of requirements is vital to the product you are to develop.
The more precisely the requirements are described at the very beginning of your development path, the more chances you have to create a quality product the first time while saving your budget and gaining time from competitors.Want to know where to start and what exactly to consider when compiling a list of requirements?

According to a report, app crashes cause 71% of uninstalls.
Other reasons that compel users to uninstall apps are page response time, confusing UI, and battery consumption.
Let’s take a look at the non-functional excipients that are commonly used in solid oral preparations.DisintegrantThe disintegration of solid oral tablets is very important, because for most solid oral tablets, only after disintegration can the subsequent drug be dissolved and absorbed in the body.
In the prescription, the use of natural polymers as disintegrants may cause the viscosity of the surrounding medium to increase due to the partially soluble nature of the polymer, thereby hindering disintegration and dissolution.
This problem can be solved by two methods: polymer crosslinking (to reduce the viscosity of the disintegrant) and introducing carboxyl functional groups into the polymer (to increase hydrophilicity).The mechanism of action of disintegrants includes swelling, gas production, capillary action, and wetting and heat production.
The effect of moisturizing and heat generation is that some disintegrants will break the chemical bonds when they meet with water, thereby releasing heat and expanding the air remaining in the tablet to promote disintegration.pH regulatorThe pH of the microenvironment can affect the solubility, dissolution, degradation rate and stability of solid preparations.
For weakly acidic drugs, calcium phosphate, magnesium hydroxide, magnesium oxide, meglumine and sodium carbonate can be used as alkalizing agents.Fillers and adhesivesThe role of filler is to provide a certain volume for the formulation, so that the formulation can be processed into shape.
Fillers can be divided into water-soluble fillers and water-insoluble fillers.
