Are you thinking Flexible?

Imagine you're building a lemonade stand. Functional requirements would be things like needing a table to hold the lemonade, a pitcher to pour it from, and a cup for the customer. These define what the stand does.

Non-functional requirements are like the quality of your lemonade stand. You want it to be sturdy enough to handle a crowd (scalability), easy to take down and put away (maintainability), and maybe even have a cute design that attracts customers (usability). These define how well the stand works.

Here's how some non-functional requirements can impact future scalability of a solution.

Performance: If your website takes too long to load for customers (slow performance), it won't scale well as you get more traffic. It's like having a tiny cup for a huge crowd - it takes forever to serve everyone!

Scalability: This refers to how well a system can handle more users or data. If your system can't easily grow as your business does, it might be like having a lemonade stand that can only hold one pitcher - you'll run out of lemonade fast!

It will bring Performance bottlenecks, Complexity, Cost and Data consistency issues.

Maintainability: Imagine your lemonade stand is built with glue and toothpicks. If you need to add something new, like a fancy umbrella, it would be a nightmare! A well-maintained system is easy to modify and add features to, which is important for future growth.

By considering these non-functional requirements during the design phase, you can build a solution that can grow and adapt as your needs change. It's like building a strong, well-designed lemonade stand that can handle a rush of thirsty customers!
