Two Slack threads sit pinned: a tool swap you can reverse, and a vendor lock you cannot. Your mouse hovers over the first thread, then the second, because you already wasted 40 minutes this week overthinking the tool swap that takes 2 minutes to roll back if it flops. The vendor thread has a deadline at EOD tomorrow, and you know if you rush that call you’ll be stuck with overcharges for 18 months. You grab the notebook to your left and flip to a blank page, because you don’t want to mix up the speed rules for each call ever again.
Gather 3 physical and digital items before you start drafting rules
You only need three things to build the table, no extra research or archived meeting notes required. First, keep the two pinned Slack threads open in a dedicated browser tab, so you can reference them as examples for high and low reversibility choices as you build each row. Second, set a 12-minute timer on your phone, face up next to your keyboard, with all non-urgent work notifications muted so you don’t get pulled into a random ping mid-draft. Third, keep your favorite pen on the open blank notebook page, no extra tabs or spreadsheets open to distract you. You won’t need more than these three items, because the table is built first for the decisions you’re facing right now, not every hypothetical choice you might encounter 6 months from now.
Fill each row of the decision speed table one line at a time
You build the table row by row, starting with the two decisions from your pinned Slack threads, then adding 2 more common decision types you face at least once a month. This table is built on the reversible/irreversible decision distinction from Find Core Insight, adjusted to fit your team’s specific workflows and cost thresholds. As you fill each row, start with the reversibility check first, not how easy the choice feels at first glance. Watch for misclassifying cheap-looking choices with high exit cost: a free software trial that requires you to upload 3 years of client data that takes 10 hours to export counts as high cost to reverse, even if the subscription itself is month-to-month, so you slot it in the irreversible category. For fully reversible choices, you can even schedule slow meetings for choices you can undo on Friday, so you don’t waste high-focus work hours overthinking small calls that can be rolled back first thing Monday if they don’t work out.
| Decision Type | Reversibility Check | Maximum Allowed Decision Time | Required Pre-Decision Step | Post-Decision Rollback Window |
|---|---|---|---|---|
| Small tool swap for 3 team members | Can undo fully without extra cost in < 24 hours | 15 minute meeting | 1 sentence note of 2 worst case outcomes | 7 days |
| 10 person team workflow change | Can undo with 2 hours of team retraining, no extra monetary cost | 1 hour sync with 2 team leads | 2-sentence feedback snippet from 1 team member who will use the workflow daily | 14 days |
| 12 month vendor contract for core project management software | Requires 18% early termination fee if cancelled before end of term, plus 8 hours of data migration to switch tools | 3 30-minute syncs with finance, legal, and core team users | Full 1-page cost breakdown of 2 competing vendors with equivalent features | No rollback without fee |
| Part-time contractor hire for 8 week short term project | Can end contract with 1 week notice, no penalty or extra payout required | 2 20-minute interviews | Reference check from 1 past client of the contractor | 30 day probation window |
You can add extra rows if you have other common decision types, like budget requests for team events or new software test runs, but stick to 4 rows max for this first draft so you don’t overcomplicate it. Each row’s maximum allowed time is non-negotiable: if a reversible decision meeting runs over 15 minutes, you wrap it up and make the call by the end of the allotted time, no extensions, because you know you can undo it later if needed.
Stop drafting the moment every rule has a clear action attached
You are done drafting the table the second every cell in every row is filled, no empty spots left, and you can point to each decision type and say exactly what speed you will use for it without hesitation. You do not need to add 10 more rows for every possible decision you might face, or adjust the rules to cover every edge case, because you can add new rows later as you encounter new decision types. If the 12-minute timer goes off before you finish, you add one extra minute per blank cell and then stop, no more drafting after that. The visible sign that you are fully done: you scrawl a small, thick check mark in the top right corner of the notebook page with the table, so you can spot it instantly when you flip back through the notebook later looking for the rules. You don’t need to type it up right away unless you prefer digital notes; the handwritten version works perfectly fine for the first week of use.
Add one quick reminder to your work calendar before closing the tab
The next step takes 10 seconds, no extra work required. Open your work calendar, find the next decision-related meeting you have scheduled in the next 7 days, and mark the next calendar invite reversible or hard to undo by adding a 3-word label at the start of the meeting title. For example, if your next meeting is the huddle to discuss the Figma plugin tool swap, you change the title from “Figma plugin test chat” to “[REVERSIBLE] Figma plugin test chat”. If it’s the vendor contract sync, you change the title to “[IRREVERSIBLE] PM software vendor sync”. This is the start of your one-week test using only calendar invites to signal decision speed to your team, so everyone joining the meeting knows up front how fast to move, no long preamble explaining the rules needed. If you want, you can add a 1-sentence note in the meeting description linking to a photo of your handwritten table, but that’s optional; the label in the title is enough for now.
Open the table 2 minutes before your first scheduled decision call next week
Next week, when you sit down at your desk for your first decision-focused meeting of the week, you pull up the notebook page (or the digital copy you typed into your notes app after finishing the table) 2 minutes before the call starts. You glance at the row matching the decision you’re making that day, confirm the allowed time and required pre-decision step, and adjust the meeting agenda if you’re at risk of running over the allotted time for a reversible call. If it’s an irreversible call, you double check that everyone who needs to weigh in is present before you start discussing options, so you don’t have to reschedule or make a call without all the required input. You don’t need to rewrite the entire table that day, just add one new row if you’re facing a decision type you didn’t account for the first time around. If a decision falls somewhere between the two categories, you default to the irreversible rules to avoid rushing a choice that might have hidden exit costs you didn’t spot at first. You can update the rollback windows and allowed decision times any time you test a rule and find it doesn’t fit your team’s pace, no full rework required.
