We turn the product idea into a testable list of requirements
Where will the user use the device, which operation will take how many steps, which features will work without internet or phone? These questions determine the scope of electronic product development. The feature list is translated into concrete scenarios: first boot, normal use, low energy, incorrect operation, and reboot. It also defines what information will be displayed on the screen or application and how the user will know when a transaction is finished.
The initial assessment considers the target market, planned production quantity, expected product service life and maintenance approach. Rapid validation with an off-the-shelf module can be useful at some stages; a custom board becomes relevant when a smaller size or different interface is needed. An option's economics depend on more than component prices. Assembly, software maintenance, testing, spare parts and product changes all form part of the overall development decision.
- Target user, core problem and initial release scope
- Size, energy, connectivity and usage scenarios
- Stage outcomes and measurable acceptance conditions
