The acronym SQDP stands for four operational areas that should be reviewed every day in a well-managed manufacturing environment:
- S β Safety
- Q β Quality
- D β Delivery
- P β Production or People
The order of these letters is deliberate. It reflects the priority of daily management: first protect people, then ensure product quality, then confirm delivery performance, and finally review productivity or workforce-related results.
A board built around this structure helps a team answer four essential questions during a short daily meeting:
- Did we work safely?
- Did the product meet quality requirements?
- Did we complete the plan and deliver on time?
- Did we achieve the expected production result or staffing level?
This article explains the meaning of each SQDP area in detail. For the full system, including board design, KPI thresholds, corrective actions, daily meetings and implementation, see SQDP Board β The Complete Guide.

What does SQDP mean?
SQDP means Safety, Quality, Delivery and Production or People. The acronym is widely used in visual management, Lean Management and Daily Management Systems to structure short operational reviews.
In practice, each letter represents one section of the board. For every area, the organisation defines:
- one or more KPIs,
- a target,
- a method of calculating the result,
- green, amber and red thresholds,
- an owner,
- a reaction rule when performance is outside target.
The SQDP board should not be treated as a static report. Its purpose is to trigger management action.
A useful daily cycle is:
- identify the deviation,
- describe the problem,
- assign an owner,
- define a due date,
- verify whether the action solved the issue.
The value of SQDP therefore comes not from the acronym itself, but from the discipline created around it.
S β Safety
The letter S means Safety.
Safety appears first because no production result should be achieved at the expense of employee health or safe working conditions.
The basic daily question is:
Did we work safely?
A very simple Safety section may only record whether an accident occurred. However, this is not enough for a mature system. An accident is a lagging indicator β it describes something that has already happened.
A stronger system also monitors leading indicators that help prevent incidents.
Typical Safety KPIs
- number of accidents,
- number of near misses,
- reported hazards,
- unsafe behaviours,
- unsafe conditions,
- days without an accident,
- completed safety audits,
- overdue safety actions,
- use of personal protective equipment,
- toolbox talks completed,
- open critical risks.
Example traffic-light definition
An amber result should not automatically be treated as failure.
For example, reporting a near miss can indicate a healthy safety culture because the team identified a hazard before it caused injury.
Leading and lagging indicators
A balanced Safety section may contain both:
Lagging indicators
- accidents,
- lost-time injuries,
- medical treatment cases.
Leading indicators
- hazards reported,
- audits completed,
- corrective actions closed,
- behavioural observations,
- safety training completion.
This combination gives the team both historical evidence and preventive information.
Q β Quality
The letter Q means Quality.
The Quality section shows whether the process delivered a product or service that meets customer and internal requirements.
The core question is:
Did we produce the correct result the first time?
Quality problems affect more than the customer. They also generate:
- rework,
- scrap,
- additional inspection,
- blocked stock,
- delayed shipments,
- overtime,
- extra transport,
- production disruption,
- higher operating cost.
Typical Quality KPIs
- number of defects,
- defect rate,
- scrap rate,
- rework,
- First Pass Yield,
- PPM,
- customer complaints,
- internal non-conformities,
- first-piece approval,
- blocked batches,
- cost of poor quality,
- overdue quality actions.
Example threshold
Assume the target is a defect rate no higher than 1%.
The thresholds should reflect the actual process target, not the desire to keep the board mostly green.
What should be visible after a Quality deviation?
When the result is amber or red, the team should be able to identify:
- the product or order,
- the defect type,
- where the defect was detected,
- the quantity affected,
- the immediate containment,
- the owner of the analysis,
- the expected completion date.
Without this context, the colour only shows that a problem exists but does not support a response.
D β Delivery
The letter D means Delivery.
Depending on the organisation, Delivery may refer to:
- shipments to the customer,
- completion of the production plan,
- internal flow between processes,
- material availability,
- schedule adherence.
The basic question is:
Did we produce and deliver the required quantity at the required time?
Delivery performance often reflects the combined condition of several functions:
- production,
- planning,
- purchasing,
- logistics,
- maintenance,
- quality,
- warehouse operations.
A missed target can therefore reveal a problem outside the immediate production team.
Typical Delivery KPIs
- daily plan attainment,
- On Time Delivery,
- OTIF,
- schedule adherence,
- delayed orders,
- missed shipments,
- backlog,
- material shortages,
- lead time,
- internal delivery performance,
- output versus plan,
- order completion rate.
Example threshold
For daily plan attainment:
A useful Delivery KPI should be available quickly.
If the team needs one hour every morning to prepare the number, the system will remain dependent on manual work and may lose relevance.
P β Production or People
The letter P does not always have one fixed meaning.
In many companies, it means Production. In others, it means People.
Both interpretations can be correct if they are clearly defined.
P as Production
When P means Production, the board normally monitors how efficiently the process used its resources.
Typical KPIs include:
- output,
- productivity,
- OEE,
- machine availability,
- downtime,
- line efficiency,
- cycle time,
- capacity utilisation,
- changeover duration,
- standard attainment,
- labour hours per unit.
Production can overlap with Delivery, so the two areas should answer different questions.
A useful distinction is:
- Delivery: Did we complete the required quantity on time?
- Production: How efficiently did we achieve the result?
For example, the production plan may be achieved only through overtime. Delivery can be green while Production is amber or red.
P as People
When P means People, the board focuses on workforce readiness, capability and engagement.
Typical KPIs include:
- absence,
- staffing coverage,
- training completion,
- skill matrix coverage,
- employee improvement ideas,
- Kaizen participation,
- turnover,
- multiskilling,
- required certifications,
- team capacity.
This version may be useful when output is already covered by Delivery and the greater operational risk is related to staffing or competence.
Which interpretation should you choose?
Choose Production when the board is mainly used to control line performance and resource efficiency.
Choose People when staffing, absence, skills or employee participation have a stronger effect on daily results.
A company can also add another category instead of forcing one letter to represent two unrelated subjects.
Why the order S, Q, D and P matters
The sequence creates a clear hierarchy of priorities:
- Safety β protect people and control risk.
- Quality β ensure that the product is correct.
- Delivery β complete and deliver the required work on time.
- Production or People β review efficiency, resources or workforce conditions.
This hierarchy prevents the meeting from starting with output alone.
A day should not be treated as successful only because the production target was achieved if:
- an accident occurred,
- a critical defect was produced,
- a serious safety standard was ignored,
- a customer shipment was missed.
The order also reduces the risk of pushing production at the expense of safety or quality.
How to choose KPIs for each area
A good SQDP board should not contain every available metric.
Its role is to provide a fast daily assessment and support action.
A suitable KPI should be:
- easy to understand,
- available every day,
- connected to an operational target,
- influenced by the people in the meeting,
- easy to calculate consistently,
- useful for triggering action,
- quick to review.
Example starting set
It is usually better to begin with one main KPI for each area than to create a board with several dozen measures.
Avoid duplicate measures
A common mistake is to place the same result in both Delivery and Production.
For example:
- Delivery should show whether the schedule was completed.
- Production should show how efficiently resources were used.
Each section should answer a different management question.
Include leading indicators where possible
Results such as accidents, complaints and missed deliveries are important, but they describe outcomes.
Leading indicators can provide earlier warning.
Examples:
- safety audits completed,
- preventive maintenance completion,
- overdue actions,
- first-piece inspection,
- staffing coverage,
- material availability.
For a broader KPI discussion, see Manufacturing KPIs β How to Measure Safety, Quality, Delivery and People.
How to use green, amber and red status
The most common visual status system uses three colours:
- green β target achieved,
- amber β risk or moderate deviation,
- red β target missed or immediate response required.
Each colour should have an objective definition.
Without written criteria, two team leaders may evaluate the same result differently.
Example: Delivery
- Green: at least 98% plan attainment,
- Amber: 95% to 97.9%,
- Red: below 95%.
Example: Quality
- Green: defect rate up to 1.0%,
- Amber: 1.01% to 1.5%,
- Red: above 1.5% or any critical defect.
Example: Safety
- Green: no accident and no unresolved critical hazard,
- Amber: near miss or reported risk,
- Red: accident or serious unsafe condition.
What should happen after an amber or red result?
A status colour is only a signal.
The board should also show:
- a short comment,
- immediate containment if required,
- action owner,
- due date,
- escalation status,
- effectiveness check.
A board that records red status without creating action becomes a historical display rather than a management tool.
SQDP, SQDC and SQCDP β what is the difference?
Different organisations use different versions of the acronym.
There is no universal rule requiring one version.
The structure should reflect the daily decisions the team must make.
SQDP versus SQDC
The main difference is the final area:
- SQDP focuses on Production or People.
- SQDC focuses on Cost.
SQDC may be more suitable for managers who need daily visibility of:
- scrap cost,
- overtime cost,
- premium freight,
- labour variance,
- material consumption.
SQDP is often more intuitive at line level because production output and workforce conditions are easier for the team to influence directly.
Do not copy another companyβs acronym without defining it
Two plants may use the same SQDP label but calculate completely different KPIs.
The value depends on:
- the operational definition,
- the selected measures,
- the thresholds,
- the action process,
- the daily meeting discipline.
Common mistakes
Too many KPIs
The board becomes a reporting dashboard instead of a daily management tool.
No clear definitions
Different people calculate the same KPI in different ways.
Delivery and Production measure the same thing
The two areas become duplicates and do not support separate decisions.
Only lagging indicators are monitored
The board records accidents, complaints and missed deliveries but does not show preventive activity.
No action after red status
The team sees the deviation but no owner or due date is assigned.
Thresholds are changed to protect the colour
The target is adjusted when performance is poor, making the history unreliable.
Missing data is treated as green
No result should not be interpreted as a good result.
The board is used to blame individuals
The purpose is to make process problems visible, not to create fear around reporting.
Frequently asked questions
What exactly does SQDP stand for?
SQDP stands for Safety, Quality, Delivery and Production or People.
Does P mean Production or People?
Both meanings are used. The organisation should choose one interpretation and connect it to clearly defined KPIs.
What is the difference between SQDP and SQDC?
SQDP includes Production or People. SQDC includes Cost instead.
How many KPIs should be used on an SQDP board?
A practical starting point is one primary KPI for each area. Additional indicators should be added only when they support a daily decision.
Should every area be reviewed every day?
In a typical SQDP system, yes. If a KPI is not available daily, it may not be suitable for daily management.
Is amber status necessary?
It is not mandatory, but it can provide an early warning before a result becomes red.
Can SQDP be used outside manufacturing?
Yes. The same structure can be adapted for warehouses, maintenance, logistics, offices and service teams.
Does every red result require an action?
A red result should at least trigger a decision. Depending on the issue, the response may be containment, corrective action, escalation or root cause analysis.
Summary
SQDP structures daily operational management around four areas:
- Safety β did we work safely?
- Quality β did the product meet requirements?
- Delivery β did we complete and deliver the plan on time?
- Production or People β did we achieve the expected efficiency or workforce readiness?
The acronym only becomes useful when every letter has:
- a clear definition,
- a practical KPI,
- a target,
- an objective status rule,
- an owner,
- a reaction process.
