The Multi-Project Conflict Spotter: A Worksheet for Finding Where Two Projects Compete for the Same Week

Published

You're running two active projects at the same time. Both have milestones landing in the next few weeks. At least one person — maybe a developer, a designer, or a key reviewer — is named on both. And right now, you have no single view that shows where the weeks collide.

That's the gap this worksheet fills. In under 20 minutes, you'll map both projects side by side, week by week, and surface the exact points where they compete for the same owner, the same dependency window, or the same slice of someone's capacity.

The result isn't a plan. It's a short list of collision points — the specific weeks where you need to make a scheduling decision before a deadline makes it for you.


Why a side-by-side map catches what a single-project view misses

Most scheduling tools and deadline checklists are built around one project at a time. That works fine when your projects live in completely separate worlds. But when two projects share even one person or one upstream dependency, a single-project view hides the real risk.

The risk isn't that Project A is behind. The risk is that Project A and Project B both need the same person to deliver something in the same week — and neither project's schedule reflects that.

Some practitioner discussions describe exactly this kind of invisible overlap as one of the harder parts of managing multiple concurrent projects. A side-by-side week map makes it visible in a way that two separate status updates rarely will.


Three types of conflict the worksheet is designed to find

Before you fill anything in, it helps to know what you're looking for. Conflicts between concurrent projects tend to fall into one of three categories.

1. Shared-owner conflicts

The same person has a committed deliverable on Project A and a committed deliverable on Project B in the same week. Both project schedules assumed that person was available. Neither schedule accounted for the other project.

2. Overlapping dependency windows

Project B can't move forward until it receives output from a step that is also feeding Project A. If Project A's work takes longer than expected, it delays the shared input — which then delays Project B, even though Project B's own schedule looked fine in isolation.

3. Capacity collisions

No single deliverable looks impossible on its own. But when you add up what a person or a team is expected to produce across both projects in the same week, the total is more than one person or team can reasonably do. The conflict is invisible until you look at both rows at once.


What you need before you start

Gather these four things. The worksheet won't take long, but it's only useful if the inputs are real.

You don't need a perfect schedule. A rough list of what each project expects to happen each week is enough to start. You can refine as you go.


The five-column worksheet

The worksheet has one row per week and five columns. Here's what each column captures.


A filled example

The two fictional projects below are called Harbour (a product launch) and Ridgeline (an internal platform migration). Both are live. Both share a developer named Priya and a QA reviewer named Tom.

Week Harbour commitment Ridgeline commitment Shared owner or resource Conflict signal
14 Jul – 18 Jul Priya completes API integration; Tom begins QA pass Priya finalises data migration script; Tom on standby for smoke test Priya, Tom High. Shared-owner conflict. Priya has full delivery commitments on both projects in the same week. Tom's QA start on Harbour depends on Priya finishing, but Priya is also committed to Ridgeline. A scheduling decision is needed before this week begins.
21 Jul – 25 Jul Harbour QA complete; stakeholder sign-off requested Ridgeline migration dry run; Tom leads review Tom High. Capacity collision. Tom is expected to complete Harbour QA and lead the Ridgeline dry run in the same week. If Harbour QA slips from the previous week, both tasks land simultaneously.
28 Jul – 1 Aug Harbour launch prep; no Priya dependency this week Ridgeline go/no-go decision requires completed migration report (from external vendor) External vendor report (shared upstream input) Medium. Overlapping dependency window. If the vendor report is late, Ridgeline's go/no-go slips. That slip would push Tom's availability back into the week when Harbour needs final sign-off. Worth confirming the vendor delivery date now.
4 Aug – 8 Aug Harbour launch day Ridgeline cutover window opens Priya, Tom, and the on-call support rotation High. Capacity collision. Both projects reach their highest-stakes moment in the same week. All shared owners are at peak demand simultaneously. This week needs explicit capacity allocation before it arrives, not during it.

The blank worksheet

Copy this into a spreadsheet, a shared doc, or print it. Fill in one row per week for the next four to six weeks. You only need to complete the Shared owner column and the Conflict signal column for weeks where something actually overlaps — but scan every row before you skip it.

What to do with what you find

When you finish, you'll have a short list of weeks marked High, Medium, or Low. Start with the High rows.

For each High conflict, ask one question: What decision, made today, would remove or reduce this collision? That might mean shifting a delivery date, splitting a shared owner's week explicitly between the two projects, or confirming an upstream dependency date before it hardens into an assumption.

You don't need to resolve every conflict right now. The goal is to make each one a conscious choice rather than a surprise.

A few things that can help once you've spotted a collision:


Running this exercise more than once

The worksheet is designed to be fast enough to repeat. Try running it at the start of each planning cycle, or any time a milestone shifts on either project. A shift on one project can quietly create a new collision on the other — and it won't show up unless you look at both rows together again.

The exercise works best when both project schedules are written down somewhere accessible. If your commitments live in separate documents, separate tools, or separate people's heads, the first step is simply getting them into the same place so you can compare them. Some practitioner discussions about multi-project coordination point to exactly this — the difficulty of comparing schedules that were never designed to be seen side by side.


How Tindlo makes this view continuous

The worksheet approximates something manually: a shared time axis where both projects are visible at once. Tindlo is built around exactly that idea.

Tindlo's multi-layer workspace separates teams, projects, and work types into parallel layers on a shared time axis — Day and Week views — so you can see what's happening across projects without switching between separate schedules. Its Google Calendar integration pulls your existing calendar events into the same view, so meetings, reviews, and external commitments sit alongside project work rather than hiding in a separate tool.

That means the side-by-side comparison you're doing manually in this worksheet becomes something you can see on an ongoing basis, not just when you sit down to run the exercise.

If you're managing two or more concurrent projects and want to try that kind of shared operational view, Tindlo is free to start.
