Build a 6-week look-ahead your site team will actually use

Your master programme is right. The trouble is nobody on site is going to open a five-thousand-activity P6 file to find out what they're pouring on Thursday. Here's the exact workflow to cut a clean, rolling six-week look-ahead straight from the master — the window filtered, the slip bars kept, a data-date curtain dropped, RAG'd by area — and re-generated in seconds every week.

The short-interval look-ahead is the one schedule the field genuinely reads. It's the six weeks in front of the crew: what starts, what finishes, what's tight, what's already slipping. Get it right and the Monday coordination meeting runs itself. Get it wrong — or, more often, don't produce it at all — and the site falls back on a whiteboard and whatever the last person shouted across the compound.

So why is it usually the ugliest, most out-of-date document on the job? Because most look-aheads are hand-built. Someone exports the master, deletes the rows that don't matter, wrestles the dates into a spreadsheet or a slide, colours a few cells by hand, and prints it. By Wednesday it's wrong, and by next Monday the whole ritual starts again. The look-ahead isn't a different plan — it's the master, cropped to six weeks and dressed for the field. Crop it, don't rebuild it.

Fig 1. The look-ahead lives inside the master, not beside it. It's the slice of the full programme that falls in the six weeks ahead of the data date — same dates, same logic, just cropped to what the field can act on this month.

Why the desktop look-ahead is a chore

Cropping six weeks out of the master is trivial in principle and miserable in practice with a desktop scheduler. You filter to a date band, then fight the layout: the bars are hairline-thin, the fonts are dense, there's no room for a legend, and the moment you tune it for print someone updates the master and your carefully-arranged page is stale. So it gets rebuilt in a spreadsheet or pasted into slides — which strips the logic, the slip and any link back to the source. The field ends up reading a hand-typed table that stopped being true days ago.

The category answer to "make it pretty" is usually a presentation add-in or a screenshot pasted into a deck. Both share the same fatal flaw: the picture is a copy, frozen the instant you made it. Next week you do it all again from scratch. A look-ahead's whole value is being current; a static rebuild is out of date before the ink dries.

Static rebuild vs. a live crop of the master Hand-rebuilt in a deck retype → colour by hand → stale Wednesday →✗ rebuild from scratch next week Cropped from the master filter window → keep slip + RAG →✓ Refresh — re-generated in seconds
Fig 2. The difference isn't cosmetic. A hand-rebuilt look-ahead is a dead copy you make again every week; a cropped view is a live lens on the master that you re-point and refresh. One is a chore, the other is a click.

The six-week look-ahead in six steps

Take a real shape — a plant turnaround with the outage split across a few areas: the boiler, the compressor train, the pipe rack and the electrical room. The master lives in P6, fully logic-linked. What the shift teams need on the wall is the next six weeks, area by area, with what's slipped shown plainly and the current date marked. Here's the version that takes seconds to re-cut each week instead of an evening to rebuild.

  1. Filter to the window. Import the master (P6 XER/XML, MS Project XML, or Excel) — it parses in your browser, nothing uploaded. Set a look-ahead window from the data date to six weeks out and filter the rows to activities that start, finish or run through it. Thousands of activities collapse to the few dozen the field can act on.
  2. Keep the baseline and slip bars. Leave the baseline switched on so each activity shows a thin baseline bar under the current one, and turn on slip bars so the gap between planned and current is drawn in red. The crew doesn't just see what's happening — they see what's moved, and by how much, without reading a single date.
  3. Drop a data-date curtain. Add the data date and a curtain shading everything to its left, so "past" reads instantly as greyed-out and the live window pops. Fill progress to the curtain and add a status line so ahead/behind is obvious at a glance.
  4. Colour by RAG, per area. Group the window into section bands — one per area — and drive a RAG stoplight off status or float using conditional symbology: green on track, amber tight, red slipping. Now the whole page answers "where's the trouble?" before anyone reads a word.
  5. Export the one-pager or share the link. Add your header, footer and logo, then export a clean landscape PDF, PNG or PowerPoint for the site cabin wall — print matches screen exactly. Or send a read-only link that rebuilds the whole look-ahead in the recipient's browser, no install, nothing to open.
  6. Refresh next week. When the master is updated, hit Refresh and point it at the new file. Sketchedule re-syncs and shows you what changed — dates moved, activities added, activities dropped — before you accept it. The window rolls forward, the slip re-draws, and the field view is current again in seconds. No rebuild, no retyping.

Fig 3. The look-ahead as it comes out of Sketchedule: a left grid with Activity / Start / Finish / % columns, four turnaround areas as section bands, task bars with thin baseline bars and red slip bars where work has moved, a shaded data-date curtain, two gate milestones and per-area RAG stoplights — all on a six-week week/day axis. This is a faithful redraw of the app view.
The whole point: you never retype a date. The look-ahead's bars are the master's dates, cropped to six weeks live — so when a superintendent asks "is this current?", the answer is yes, and next Monday's version is a Refresh away, not another rebuild.

What makes the field actually read it

A look-ahead the crew ignores is worse than none — it signals that planning and the field aren't looking at the same thing. Three details turn a cropped programme into a page people trust on the wall.

Slip bars, so movement is visible

A bare current bar tells you when work is happening. A baseline bar with a red slip bar tells you it's two days later than we said — and that's the conversation the coordination meeting needs. Keeping the slip in the field view means the crew argues about the right thing: recovering the days, not whether they exist.

Anatomy of a slip bar Tube renewal baseline (as planned) current (from the master) slip = 2 days late The field reads the red, not the dates: this one moved right, and by how much.
Fig 4. The slip bar in close-up — baseline above, current below, and the red span that measures the delay. Carry this into the look-ahead and every slipped activity flags itself; the crew never has to compare two date columns in their head.

A curtain, so "now" is unmistakable

Six columns of week bars blur together fast. Shade everything left of the data date and the eye snaps to the live window: past is grey, ahead is bright, and the current date is a hard line down the page. It's a small thing that does a lot of work on a busy wall in a noisy cabin.

RAG by area, so the trouble finds you

Grouping by area and colouring each band's stoplight means the superintendent reads the page in the order that matters: red areas first. On our turnaround that's the compressor train — one glance, before a single bar is studied, and the meeting starts where it should.

Where the source of truth stays. The look-ahead is a cropped, dressed view of the master — it doesn't reschedule anything. Critical path, float, logic and the real dates still live in P6 or MS Project; Sketchedule crops and presents them. Keep the engine as the master, and stop hand-rebuilding its output for the field every week.

Keeping it in step, week after week

The reason short-interval look-aheads decay is friction: if refreshing one is a half-day job, it quietly doesn't happen, and the wall goes stale. Cut that to a Refresh and the discipline sticks. Each week you re-point the same view at the updated master, review the diff — what moved, what's new, what dropped out of the window as it rolled forward — accept it, and re-export or re-share. The look-ahead becomes a living artefact that always shows the real six weeks, because it's cropped from the real programme every single time.
