Product managers who are not from engineering backgrounds often struggle to evaluate embedded systems engineering work. The discipline is technically specific, the outputs are often invisible until something goes wrong, and the schedules are harder to estimate than software-only development.
This overview explains embedded systems engineering in terms that help non-technical product leaders set realistic expectations and ask the right questions.
What Embedded Systems Engineering Produces
Embedded systems engineering produces firmware, the software that runs directly on a product’s microcontroller or processor, and the integration work that makes that firmware interact correctly with the hardware.
Unlike application software that runs on a standard operating system, embedded firmware runs on bare metal or a real-time operating system (RTOS) with direct access to hardware resources. The firmware controls peripheral devices, manages communication buses, handles sensor data, and executes the logic that makes the product function.
IDC research, identifies embedded and edge computing software as one of the fastest-growing segments of the global technology market, reflecting the proliferation of connected and autonomous devices across every industry sector.
Why Embedded Engineering Schedules Are Harder to Estimate
Software development schedules have become more predictable over the past two decades through the adoption of agile methodologies. Embedded engineering schedules are harder to predict because hardware dependencies introduce variables that software-only development does not face.
When hardware revisions are needed, they require PCB manufacturing turnaround times that typically run two to four weeks. A single hardware bug discovered during firmware development can add a month to the schedule.
Product managers who understand this can plan more effectively by ensuring hardware design reviews happen early and thoroughly, reducing the probability of late-cycle hardware changes.
Questions Product Managers Should Ask
- What is the hardware revision plan? Are there prototype iterations built into the schedule?
- What is the hardware-firmware integration testing approach?
- What are the real-time performance requirements, and have they been verified on target hardware?
- What is the power consumption target, and has it been validated against the battery life requirement?
Key Takeaways
Embedded systems engineering is not a black box that product managers should stay out of. The scheduling, quality, and cost of embedded development depend on decisions that product managers influence, including hardware revision frequency and integration testing investment.
Understanding the basics of the discipline helps product managers ask better questions and set realistic expectations.
