Digital work instructions: a guide to replacing paper

Digital work instructions show an operator how to perform a task at the point of work. They can combine text, pictures, drawings and required checks. Their value depends on whether the operator gets the right instruction for the job and whether the resulting record shows what actually happened.

A paper job traveller usually does more than explain the task. It also identifies the job, moves it between operations and collects evidence. Replacing the sheet therefore needs two decisions: how people will receive instructions, and how they will record completion, readings and exceptions.

Digital work instructions, SOPs and job travellers

An SOP describes a repeatable procedure and its responsibilities. A work instruction explains a specific task in enough detail to carry it out. A job traveller follows a particular order, batch or part through its route. One document can contain elements of all three, but separating their purposes helps you decide what belongs on the operator’s screen.

A PDF displayed on a tablet can be a useful first step. It does not, by itself, enforce a sequence or collect a measurement. Interactive instructions may add those controls, but each needs to be checked against the product and configuration you intend to use. For example, PICO’s published work-instruction features distinguish media display, version control and operator questions.

What to put in each instruction

Write for the person doing the work, at the moment they need the information. A close photograph of the correct orientation can be more useful than a paragraph describing it. A clear acceptance limit is more useful than “check carefully”.

Element	What the operator needs
Identity	Part or product, operation and applicable revision
Preparation	Required material, fixture, tool and preconditions
Action	A clear sequence, with images where they clarify the task
Acceptance	What a correct result looks like and the approved limits
Evidence	Which readings, identifiers or confirmations must be recorded
Exception	What to do if the part, tool or result does not match

Take a hypothetical seal-fitting operation. “Fit seal and inspect” leaves room for interpretation. A better instruction identifies the seal, shows its orientation, explains the seating check and says how to report damage. The actual limits and method must come from the approved engineering instruction, not from a generic template.

Control revisions before removing paper

Decide what happens when engineering changes an instruction while a job is already running. Automatically replacing every open screen with the newest file may be wrong for work that must finish against an earlier approved revision. Equally, leaving every job on an old copy can perpetuate a known problem.

Ask the software supplier to demonstrate both a new job and a job already in progress through a revision change. Check who approves the change, how applicability is selected, what the operator sees and what history remains afterwards.

The same principle applies to sign-offs and competency. An authenticated confirmation identifies who used an account; it does not prove that a physical inspection occurred. A training record is useful, but it becomes a gate only where the execution workflow actually checks it. Test expired training, shared-station sign-in and an attempted action by the wrong role.

What Bulk puts at the workstation

Bulk’s Production interface includes access to instruction PDFs associated with the processes of jobs loaded on an asset. The instruction list identifies the process and revision and opens the selected PDF. That connects the reference material to the work being run, rather than asking an operator to search a shared folder.

Treat that document access separately from any requirement for interactive step enforcement, signatures or competency checks. Demonstrate those requirements in the actual route before retiring the paper control. The document library and training records are related parts of the evaluation, not proof that every operation is automatically gated.

Pilot one traveller from start to finish

Choose a representative operation with a clear owner. List every box on its paper traveller and the downstream person who uses it. Remove fields that have no purpose only after checking contractual and quality requirements. Then decide where each remaining value will be captured and retrieved.

Run a normal job, a failed check and an interrupted job through the proposed setup. Include the operator who usually runs the station and someone less familiar with the task. Watch for awkward scrolling, unreadable drawings and confirmations people click through without reading.

Test lost connectivity and recovery on the actual device. If the required action cannot be completed offline, define the approved fallback and how its records will be reconciled. Do not infer offline support because a page stayed visible after the connection dropped.

Before removing the traveller, retrieve one completed job’s instruction revision, required results and exception history. If that record is incomplete, fix the capture or the retrieval first. Use the SOP template guide to improve the underlying procedure, then assess how production execution will carry it at the station.
