If you are scoping an idea for a website or software and want to ensure that you have the best possible chance of success, then it is important to give a professional agency the opportunity to truly explore your idea. Scoping websites and scoping software can be very different from each other, so make sure that you understand what type of scoping phase would be appropriate for your needs. Some scopes may require only minimal investment in order to test out some ideas before committing more time and resources. Others might need heavy up-front investments because they involve complex tech requirements like database architecture, UX/UI design, and development, or integrations in order to accomplish the MVP (Minimum Viable Product) or MMP ( Minimum Marketable Product).
If truly understanding your big idea is your goal, then consider giving a professional agency the opportunity to truly explore and help with scoping the website, software or app - from understanding how scopes are different than wireframes or prototypes, what kind of investment would be needed (minimal or heavy), and if there are any UX/UI considerations before proceeding, partnering with a well-traveled, well-staffed agency to perform the earliest task, could provide you with critical visibility into the complexity or simplicity of your big idea.
The scoping phase is so much more than a quick google search or an informal chat with someone who knows the business, industry or can just help you envision the seed investment and the potential virality of the idea. It provides critical insight into your vision in order to make educated decisions about how you might proceed, and whether it's worth doing at all from a time & money investment standpoint.
