Checklists and evidence

Who this is for: field workers.

What you will learn: how to complete a checklist correctly and capture evidence that will stand up to review.

Job checklist

How a checklist behaves

  • It is a snapshot of the template when the job was created.
  • Every item has a type and may be required.
  • Some items only appear when a previous answer unlocks them.
  • Required evidence is shown next to the item.
  • You must save each step.

Item types

Type What to do
Checkbox Confirm the step is done
Pass / fail Record the inspection result
Yes / no Answer the confirmation question
Number Enter the reading and unit
Text Write a short, factual observation

Record a reading

  1. Enter the value.
  2. Check the unit (bar, °C, Ω, mm).
  3. If the value is outside the allowed range, the screen asks for an action.
  4. Record exactly what you did:
    • adjusted
    • isolated
    • reported
    • made safe
  5. Save the step.

Do not change a reading to fit the range. A real out-of-range value is useful data.

Evidence rules

Stage What to capture
Before The condition on arrival, wide shot and close-up
During The work in progress, where it adds proof
After The completed work, cleaned and tested
Defect The fault, clearly visible, with a reference

A photo must show what the caption says it shows. If you write "leak at mechanical seal", the seal must be visible.

If a photo will not upload

  1. Check signal.
  2. Keep the app open; uploads may be queued.
  3. Try a smaller photo or the gallery.
  4. Do not delete the job or clear app data.
  5. Tell the office before you leave site.

Failed items and defects

A fail is not the end of the job.

  1. Record the failure.
  2. Add a photo if required.
  3. Record a defect with severity and impact.
  4. State whether the asset is still available.
  5. State what parts or follow-up work are needed.
  6. Tell the customer what they must not use.

Tips

  • Tip: Complete the checklist in order. Conditional items depend on earlier answers.
  • Tip: Write observations a stranger could understand a year later.
  • Warning: Do not mark an item as not applicable without a reason if the checklist asks for one.

Check your understanding

  1. What happens when a reading is outside the allowed range?
  2. What are the four evidence types?
  3. What should you do if a required photo will not upload?
