Smartsheet's insight is that a great many project managers already run their projects in Excel and do not want to stop. So it keeps the grid, the formulas and the familiar mental model, and adds the things a spreadsheet cannot do: dependency aware scheduling, resource management, automated approvals, forms and a real audit trail.
In South Africa it shows up most often in construction, engineering, mining services and formal project management offices, which is exactly where it fits.
Where it is the right answer
Critical path scheduling with dependencies and baselines. Resource allocation across many concurrent projects. Approval workflows that need a documented trail. Portfolio roll ups where a programme director needs one view across thirty projects. Cross project reporting that actually works.
The formula language is close enough to Excel that a competent spreadsheet user is productive immediately, which is a real adoption advantage over tools that require a new way of thinking.
Where it disappoints
The interface is utilitarian. It is a grid, and next to monday.com it looks like work. Teams used to visual boards find it dry. The learning curve for the advanced features, particularly resource management and cross sheet formulas, is genuine.
Pricing is in dollars per user per month, and the tier that includes resource management and portfolio reporting is the expensive one. Small teams will find better value elsewhere.
Who should buy it
Construction and engineering firms, project management offices, and organisations running many concurrent projects with shared resources. Teams whose projects are simple should not pay for this.
