Shortage, Excess and Imbalance Analysis

Three reasons a daily total is not enough

First, pause when demand and capacity use different units or windows. A request count is not staff time until a conversion is stated, and estimated capacity is not measured throughput. Separate session-level records before aggregating. If some sessions are unknown, label the total as partial rather than replacing missing values with zero.

Second, do not treat spare capacity as waste automatically. It may cover variability, interruptions, quality checks, or work requiring a different skill. A later idle period cannot meet an earlier need without changing timing or the service arrangement. Investigate the actual flexibility before suggesting a shift or a staffing reduction.

Third, stop before converting a practice difference into a cause. Different forms or versions may be associated with missing information, but the record also needs task context and alternative explanations. The shortage, excess, and imbalance lenses can describe the same issue; counting each label as a separate saving would duplicate a claim.

Choose between local gaps, redesign, contribution, and causes

These three lenses organize an evidenced issue list. They do not rename another lean taxonomy or rate employees. Choose a related method once the missing output becomes more specific, keeping the same units and time boundary.

Keep Clearbrook’s morning gap visible

The complete fictional I5 record is October 5 at Clearbrook Support. Demand and capacity are request-equivalents per session, assuming five staff-minutes per request and sixty available staff-minutes per session. AM demand is 18 and capacity 12; PM demand 6 and capacity 12; EV demand and capacity are both unknown. These are teaching assumptions, not observed waiting times, completed requests, or staffing requirements.

AM therefore has six request-equivalents of shortage, equivalent to thirty staff-minutes under the stated conversion. PM has six request-equivalents of unused capacity, also thirty staff-minutes. The known sessions total 24 demand and 24 capacity, but that equality does not eliminate timing constraints or establish a full-day balance. EV remains missing.

A separate audit examines ten of fifty trial forms and includes two missing-owner records. The v1 and v2 fields differ. This is a practice-variation lead, not a population estimate or proof that the version caused either case. A proposed shift or earlier booking requires skill, timing, buffer, and permission checks before any trial.

Define a small test without spending the same capacity twice

First confirm what a request-equivalent represents and whether the five-minute assumption is credible for the work considered. Different complexity or skills can make an average misleading. Retain the underlying records and quality floor instead of treating every request as interchangeable.

For a proposed timing change, identify who can move which work, who must agree, and which demand can genuinely move earlier or later. Count any booking, coordination, or checking work the change adds. The afternoon amount cannot simultaneously be a buffer, a transferred resource, and a saving.

Before an authorized trial, specify its scope, owner, stop condition, and measures for demand, capacity, completed work, waiting, and quality. Keep these measures distinct; more completed forms need not mean fewer errors or shorter waits. No reallocation or improved outcome has been supplied here.

At review, compare like sessions and include unknown or unresolved cases. Investigate the two missing-owner records separately from the load arithmetic. The decision may be to collect data, alter timing, standardize instructions, or leave a buffer intact. Explain the evidence behind it without turning an analytical label into a staffing judgment.
