Direct Answer
Manage multiple projects by maintaining a master dashboard showing all active projects' schedule status, a weekly cross-project resource allocation review, and by assigning a dedicated project manager to each major project. The single most common failure mode when running multiple projects is resource conflict — the same detailer, the same CNC machine, or the same key welder needed by two projects simultaneously.
Full Explanation
Multi-project management requires: (1) A master project dashboard — one view showing all active projects, their fabrication stage, shipping status, and any critical issues. (2) Centralized resource scheduling — CNC machine hours, key equipment, and skilled welder assignments planned across all projects simultaneously. (3) Buffer management — build schedule buffers into each project plan and use them intentionally when a problem arises, rather than letting one project's problem cascade to the next. (4) Clear escalation paths — when a conflict arises, there must be a clear decision-maker who resolves it without delay.
What This Means for Your Shop
The growth risk for small-to-mid-size fabricators is taking on too many projects simultaneously. Five projects running at 60% efficiency is worse than four projects at 90% efficiency. Know your shop's true capacity and protect it.
Common Mistakes
Taking on a new project when the shop is already at full capacity because 'we'll find a way.' This is how shops miss delivery dates on every project simultaneously.
Recommended Process
Implement a weekly cross-project operations meeting with the shop foreman, project managers, and estimating. Review capacity for the next 8 weeks across all active projects. Before accepting a new project, confirm available capacity for its critical fabrication window.
