A practical problem gives the plan a purpose

A community vegetable-box service is open only during working hours. Some intended users report that they cannot collect their boxes. The organisers propose evening collection. Before buying equipment or expanding production, they need to define the problem: which people face the barrier, and is timing the important constraint?

A food-system improvement begins with that concrete question. More boxes packed is not automatically better access. People may also face transport, cost or suitability barriers. Describe the existing service and observations before naming the change that supposedly solves them.

Specify the intended people and useful service

State who is eligible and how their outcome will be observed. A count of orders differs from a count of unique people or households. Repeat collection by one household should not silently count as reaching another household. Keep the food's intended function visible; one box definition should not change halfway through the comparison.

Include the people whose work makes the service possible: growers, packing staff, drivers and collection-site workers. Ask those who do not currently use the service about barriers too. Participation in planning can reveal constraints that a convenient list of current customers misses. It does not itself prove which proposed option will work.

Define what the pilot will observe

For this case, a practical boundary could run from accepted vegetables entering the packing service to boxes received at the collection point. State the location, pilot period and included staff time. Connect upstream production, transport and downstream use where they could change the conclusion; excluding them from measurement does not make them irrelevant.

The boundary should be narrow enough to investigate but wide enough to capture the main possible burdens. Longer opening hours may shift staff schedules or require additional utilities. Existing process-specific food-safety and suitability requirements remain applicable. Their operational design belongs in neighbouring articles, not in an invented collection-hour recipe.

Make the target observable

In an invented starting record, 40 of 80 eligible households collect the defined box in one week. The observed share is 50%. Organisers propose a pilot goal of at least 56 of the same 80 eligible households collecting in a comparable week, or 70%. The proposed change is 16 households and 20 percentage points on that fixed denominator.

This is a planning target, not a measured improvement or a universal access standard. Decide how eligibility, receipt, cancellations and missing records will be handled before collecting results. A change in the group or product definition needs its own explanation. A later successful count would still not isolate the evening-hours effect by itself.

Invented baseline and proposed pilot target
Record	Baseline	Proposed target
Defined eligible households	80	80
Households collecting the box	40	At least 56
Collection share	50%	At least 70%

An observed baseline and a proposed target

Original hypothetical planning comparison; arrows show the proposed review question, not an observed trend or causal effect. Keep eligibility and counting rules unchanged or disclose revisions.

Read the diagram as text

The invented baseline has 40 collecting households out of 80 eligible households. The proposed threshold is 56 of 80, or 70%; it remains a target for investigation.

Parts

80 eligible households: Same defined group and box function for comparison
Baseline: 40 collect: Observed 50% in the stipulated starting week
Target: at least 56 collect: Proposed 70%; 16 more households, not an achieved result

Connections

80 eligible households → Baseline: 40 collect: observe receipt
Baseline: 40 collect → Target: at least 56 collect: plan +16

Attach resources and conditions to the goal

The plan needs more than a desired count. Specify who records receipt, who supervises collection and what resources the change uses. For an invented six-week trial, two additional one-hour sessions each week require 12 session-hours before adding preparation, cleaning or other duties. Hours open are not automatically equal to person-hours if several staff are needed.

Record stopping or revision conditions and retain a usable existing service. If participation creates unexpected access or staff burdens, reconsider the arrangement. A small reversible change can answer a bounded question without committing the organisation to a permanent larger facility.

Keep the improvement open to review

A clear statement connects people, function, boundary, goal and evidence:'Test evening collection for the defined group over six weeks; record receipt, staff demand and barriers using the same rules, and review before extending it.' It leaves the expected benefit as something to learn rather than an established outcome.

Shared system-boundary and uncertainty Foundations support the record. Neighbouring topics develop option comparison, pilot feedback and causal interpretation. Readers can use the method for a useful local question without completing a course or adopting the invented target.

Worked examples

Read a proposed access target

How does the invented 56-of-80 goal differ from the 40-of-80 baseline?

Compute 40/80=50% and 56/80=70%.
The difference is 56−40=16 households and 70−50=20 percentage points.
Label 56 as a proposed threshold, not a result already achieved.

The goal proposes a 16-household increase on the same eligible-group basis. It is not evidence that the service or intervention has produced it.

Count opening time carefully

What time does two additional one-hour sessions per week over six weeks describe?

Multiply 2×1×6=12 session-hours.
Add separately any preparation, travel, cleaning and recordkeeping.
Convert to person-hours only after stating how many staff attend each session.

12 hours of additional opening time, not a complete labour budget or a verified capacity forecast.

Check your understanding

Does packing more boxes alone establish that the intended households obtained them?
Show answer and reasoning
No.
Production output and actual receipt by the intended group are different observations.
Should the same household be counted as two new households because it collects twice?
Show answer and reasoning
No.
Retain the chosen unit and avoid duplicate people or household identities.
Is a proposed 70% collection goal a universal food-security standard?
Show answer and reasoning
No.
It is an invented local planning target with an explicit group, function and period.

Key ideas

State the intended people, food function, boundary and period.
Make the goal observable while preserving its status as a target.
Include burdens and resources that the change could shift.
Define the record and review point before wider commitment.
