When analyzing the specifications, defining the required steps, and assigning priorities, several factors may have to be taken into account. Consider having to design an air quality monitor device, with a PM10 air quality serial sensor, which collects the measurements done hourly into the internal flash, then transmits all the statistics daily to a gateway using a wireless transceiver. The target system is a custom board based on Cortex-M MCU, which is adequately sized to run the final software. The final hardware design will not be available until some real-life measurements are done on the transceiver transmitting data to the gateway.
The list of steps to be performed to reach the final goal, resulting from these ...
