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.
Functional vs Non-functional Requirements: List & ExamplesPrecise 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.

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.
This approach is formulated by international regulatory bodies that employers and employees follow in tandem, wherein the regulations depend on the nature of work an organisation performs.
This leads us to the topic of functional safety compliance.SO, WHAT IS FUNCTIONAL SAFETY-COMPLIANCE?Before we dwell on functional safety compliance, it is important to understand the context and definitions of different aspects that constitute functional safety.
This could be caused either directly or indirectly from damage to property or the environment.
Risk on the other hand, can be defined as the amalgamation of the severity of harm that can be caused, and the probability of harm being caused.Functional safety can then be defined as the process of achieving the “absence of unwanted/unreasonable risk that is caused by hazards which take place due to malfunctioning of programmable/electrical/electronic systems.” Functional safety is a pivotal part of the overall safety that ensures a system or equipment is operating appropriately to the inputs.Failure in an operation can either be a Systematic Failure which can be eliminated only by changing the operational or manufacturing process, design and procedures; or can be a Random HW Failure which can occur at any point, unpredictably, during the lifetime of the process.Now that we have addressed the basics, let us define functional safety compliance.
In simple words, functional safety is a part of the overall safety that depends on a system or equipment operating correctly in response to its inputs.WHAT ARE FUNCTIONAL SAFETY STANDARDS?Safety-critical industries need to comply with safety standards pertaining to their industrial sector.
Here is a list of a few Functional Safety Standards associated with different Industries.IEC 61508: Functional safety of electrical/electronic/programmable electronic safety-related systems ISO 26262: Automotive IEC 61511: Process Industry IEC 62304: Medical Devices EN 50126, EN 50128, EN 50129: Railway Applications (Signaling and Rolling Stock) ISO 25119: AgricultureWHY IS FUNCTIONAL SAFETY MANAGEMENT IMPORTANT IN THIS DAY AND AGE?There is a certain degree of risk in every activity that is undertaken, and as a society, we look at mitigating and dealing with these risks in different ways.
