Consulting Partner Implements OKR Framework for Starter; Q2 Objective: 'Achieve Reproducible 4.2pH Environment'

The levain Derek Paulson maintains at 83% hydration had entered hour three of a projected 4.5-hour bulk fermentation window when he opened his laptop and began updating the Q1 progress cells in the OKR tracker he'd built in Notion specifically for it. The Q1 close-out deck was due to his wife by 7pm. He had forty-two minutes.

Paulson, a partner at a management consultancy whose clients pay $340,000 annually for strategic clarity frameworks, applied those same frameworks to his sourdough practice in January following what he described — in an incident retrospective he wrote and circulated to no one — as "an alignment failure": three consecutive loaves with inconsistent oven spring, traced to unmanaged ambient temperature variance between 11pm and 6am. The root cause was addressable. The solution was an Inkbird IBS-TH2 Pro mounted at counter height, a webhook piping its readings into a Google Sheet, and a conditional-formatting risk matrix flagging anything outside 74–78°F amber and anything outside 72–80°F red.

The starter's name is Meridian. Paulson named it after the firm. He has described this, when asked, as "just a thing that happened."

Meridian's Q2 objective — formalized in a shared Notion workspace that Paulson's wife, Sarah, has been invited to but has not opened since the onboarding email he sent March 4th — is to "achieve a reproducible 4.2 pH fermentation environment across no fewer than eight consecutive feeding cycles." The target is sound: 4.2 sits comfortably within the 3.5–4.5 range associated with a balanced lactic-to-acetic acid ratio in a mature wheat-rye culture. Gertrude, my own 14-year rye, holds 4.1 on her best days, which I note in my lab notebook as S/LA — stable, lactic ascendant. The issue is not Paulson's target. The issue is the supporting documentation, which runs to eleven slides.

Three key results. KR1: hydration maintained within ±2% of 83% across twelve consecutive feeds. KR2: bulk fermentation window standardized to 4.5 hours at 76°F ambient. KR3, added in the March revision after what the tracker logs as a "scope expansion event": crumb porosity variance below 18%, measured against a reference photograph printed at 4×6 and stored in a labeled sleeve in the kitchen drawer.

The photograph is of a loaf from February 9th. Paulson considers it a 10. It is, by any structural measure, a 10. He has not told Sarah why it is laminated.

The weekly QBR runs Sunday evenings. Paulson presents six slides — executive summary, prior-week KR performance, variance analysis, risk register, action items, and an appendix he calls "qualitative observations" containing tasting notes formatted as bullet points. Sarah attends. Last month, during the risks slide, she suggested the starter might benefit from a less structured environment. Paulson logged this as a stakeholder concern in the open issues tab before explaining, with what she later described to her sister as "his teaching voice," the role of consistent ambient temperature in Lactobacillus sanfranciscensis metabolic activity at 76°F — the inflection point where lactic acid production dominates without the acetic sharpness that emerges when temperatures drop below 70°F and yeast activity slows relative to bacterial fermentation.

He was not wrong. Sarah knows he was not wrong. This does not help.

There is also a Slack channel. It is called #meridian-ops. Paulson is the only member. He posts feeding logs at 7am and 10pm, formatted as situation reports: time, temperature, starter weight pre- and post-feed, observed activity at the 4-hour mark, and a single-sentence assessment. The April 1st entry reads: "Signs of early hooch formation detected at 18h; adjusted to 1:2:2 feed ratio; root cause likely 73.8°F ambient reading logged Thursday — flagged in risk matrix, mitigation applied." There have been forty-one posts. He has never scrolled up to read them.

The April 2nd bake produced an open crumb with irregular alveoli distribution that Paulson scored 9.1, his highest since the February 9th reference loaf. He filed a post-bake incident report noting favorable conditions: 76.3°F ambient, 62% relative humidity, 4h 28m bulk fermentation, a 31-minute cold retard extension approved via a change-request process he implemented after an unauthorized schedule deviation in week seven produced what the tracker classifies as "an acceptable but non-reproducible outcome."

The Q3 objective is still in draft. Early working language: "Establish scoring as competitive differentiator through motif standardization." The column for stakeholder sign-off lists Sarah's name. The cell is empty.

She told him last week that she wants to learn to score.

He has scheduled an onboarding session for Thursday.
