The main filter I use when deciding whether to implement a change request is whether the constraint (forcing the change) that the customer has identified actually costs the customer anything to impose, or is just a preference of theirs that they are treating as if it were a constraint. In hardware-backed systems, there are many more costs to making a change in the middle of a cycle than the line item in the contract. Thus, one has to requalify, retest, re-stock engineering, etc. So, the criteria for accepting a change request into a plan for a hardware-backed system is: 1) is it tied to increasing revenue or retention for the requester; 2) are multiple customers asking for this change; 3) does this not revisit work that has already been validated. If any of these criteria are not met, then the change request gets rolled to the following cycle. The loudest person asking for change requests in a hardware-backed system for big accounts is most likely wrong. Big accounts ask for custom work. Most of the wider market wants consistency. 2\. A very large broker client once asked us to switch from our standard CPU (e.g., Intel Core i7) to a "faster" one (e.g., Core i9) in the middle of our rollout. In theory, the new processor would execute faster. In reality, we had to re-tune the BIOS for the new silicon and re-run our latency benchmarks. The end result of all this extra work was about 3-5 ms of additional latency that the client's strategy couldn't even take advantage of. Nowadays, we require the requester to explain how their change will affect their real metrics (and not just some spec sheet number). We also "flash freeze" all hardware under test once validation has begun and all new silicon goes into the next build. --- ### Block Local Exceptions That Threaten Governance Choosing what modifications to incorporate in a complicated manufacturing program relies on a formal Impact Analysis that compares the cost of interference with an eventual ROI. Large-scale implementation of systems makes it clear that asking whether the request is good enough is not sufficient; one should figure out whether it will make the program fail. If a request is not connected to a major problem in the main process or does not deal with a required regulatory change, it is normally a distraction. I analyze these interferences by studying the amount of technical debt caused by them and the 'Change Management Tax' they inflict on workers. There is one example of a change request that clearly showed my team the importance of preserving priorities. The request was connected with the modification of a procurement workflow due to the vendor's request during the project. It seemed to be an insignificant change, and we proceeded to make it in order not to stop the process. However, this little change had a huge impact on the global compliance template we had been elaborating on for weeks. We had to spend lots of time on regression testing in order to eliminate data inconsistencies caused by this change. What this experience has taught us was to understand that in order to protect project priorities, it is crucial to protect global designs from local exceptions. Today, we apply the 'Change filter' to all changes: if it alters the governance profile or the definition of a transaction, the request will require approval from a steering committee, regardless of its appearance and format. The final point is that the major criterion of the correct interference is whether the operations and IT divisions have determined a revised definition of 'done'. If a change request has rewritten the finish line with no increase in the operational ROI, it is rarely reasonable to approve the change. --- ### Reject Complexity That Betrays Core Users I'm Runbo Li, co-founder and CEO of Magic Hour. The framework for evaluating mid-stream change requests is the same whether you're building chips or building AI products: every change has a cost, and most people dramatically underestimate it. The way I think about it is what I call "disruption debt." Every change you accept mid-plan doesn't just cost the hours to implement that change. It costs the context-switching tax on your team, the downstream rework on everything that touched the original spec, and the invisible cost of resetting momentum. So the filter I use is simple: does this change unlock a fundamentally different outcome, or does it just make someone more comfortable? If it's the latter, it's a no. Here's a real example that taught us this the hard way. Early on at Magic Hour, we had a template system that was working well. A wave of user feedback came in asking us to add granular parameter controls, things like specific frame rates, custom aspect ratios, advanced model settings. It felt like a reasonable ask. These were paying users telling us what they wanted. So we started building it. Halfway through, we realized we were solving for the 2% of power users while actively making the experience worse for the 98% who came to us because they didn't want to think about parameters. We had disrupted our own roadmap to chase a change request that sounded urgent but conflicted with our core thesis: simplicity is the product. We killed the feature mid-build. That hurt. But the lesson was permanent. Now every change request runs through one question first: does this move us closer to the person who has never edited a video before, or further away? If it pulls us toward complexity, it doesn't matter how loud the request is. In semiconductors the stakes are higher because physical production cycles are unforgiving. But the principle is identical. Protect the user you're actually building for, not the loudest voice in the room. The best product teams don't say yes to good ideas. They say no to good ideas that don't fit. --- ### Hold Recurring Cross-Functional Priority Reviews Scheduled cross-functional reviews help teams confirm that priorities still match the product goal. These meetings should include the groups affected by changes, such as architecture, RTL design, verification, firmware, validation, and program management. The team can review new requests alongside tape-out dates, available resources, and known technical risks. This creates a regular point for stopping low-value work before it consumes more effort. It also gives each group a chance to explain dependencies that may not be visible to others. Set a recurring priority review and use it to confirm the next critical work. ### Maintain One Versioned Needs Ledger A single, versioned requirements backlog gives semiconductor teams one trusted place to find current needs. Each change should include a date, source, reason, and approval status. This record prevents engineers from building against old documents or informal messages. Version history also helps the team understand why a feature, performance target, or test condition changed. Clear access rules ensure that everyone sees the same approved baseline. Create and maintain one versioned backlog for every requirement change. ### Assign One Arbiter for Competing Demands One accountable owner should resolve conflicts when requirements compete with each other. This person can bring together design, verification, software, product, and manufacturing views before making a decision. The owner does not need to make every choice alone, but they must ensure that no conflict remains unclear. A clear decision maker prevents teams from waiting on long email threads or acting on different assumptions. The final decision should be recorded with the affected schedule, cost, power, area, and risk. Assign a named owner for resolving requirement conflicts today. ### Protect Interface Contracts From Change Damage Interface contracts limit the damage when one part of a chip or system changes. A contract clearly defines signals, timing, data formats, power behavior, error handling, and ownership between connected blocks. When a requirement changes, the team can first determine whether the contract is affected. If the contract remains stable, downstream teams can continue their work with less disruption. If it must change, the contract identifies exactly which teams need to update designs, tests, or software. Define and protect interface contracts before the next requirement update arrives. ### Explain Every Priority Decision Clearly Teams stay aligned when leaders explain the reason behind every important priority change. A short decision note can describe the customer need, technical limit, schedule effect, and tradeoff that shaped the choice. This helps engineers understand why one feature moved forward while another was delayed or removed. Consistent communication reduces rumors and keeps teams from reopening decisions without new facts. It also makes it easier for managers to answer questions from partners and customers. Share clear decision reasons whenever priorities change. ## Related - [How Semiconductor Teams Make Smarter Late-Change Decisions](https://semiconductormagazine.com/qa/how-semiconductor-teams-make-smarter-late-change-decisions.md) - [How Semiconductor Teams Stay on Track When Trade and Export Rules Shift](https://semiconductormagazine.com/qa/how-semiconductor-teams-stay-on-track-when-trade-and-export-rules-shift.md) - [Plan Semiconductor Production Capacity Under Uncertain Demand](https://semiconductormagazine.com/qa/plan-semiconductor-production-capacity-under-uncertain-demand.md) - [How Semiconductor Teams Prevent Costly Handoff Surprises](https://semiconductormagazine.com/qa/how-semiconductor-teams-prevent-costly-handoff-surprises.md)
