GanttPRO Alternative: When the bar chart needs resource planning behind it
A Gantt chart shows when something should happen. It does not by itself show whether it can happen. That is where a Gantt-only planning approach reaches its limit, and where Rillsoft Project starts.
Teams that use GanttPRO and notice that bars can be moved while the employee behind them is already planned three times are usually not looking for a prettier visualization. They are looking for planning logic that would have made the conflict visible earlier.
What GanttPRO does well, and where it structurally ends
GanttPRO is designed as a visual planning tool. Creating activities, entering durations, drawing dependencies and setting milestones works well. For one project with a dedicated team, that can be enough.
The boundary appears when three conditions meet:
- Several projects run at the same time
- They share the same employee or machine pool
- Dates must be reliable, not only displayed
At that point, a Gantt tool is no longer a complete decision basis. It can show parallel bars while the engineer behind them still has only 40 hours per week.
The concrete break: utilization is not calculated deeply enough
GanttPRO provides workload views that summarize hours and can indicate overload. That is useful, but the focus is not on resolving cross-project conflicts, checking qualifications, translating buffer times into planning decisions or treating machine capacity with the same logic as personnel capacity.
Rillsoft Project goes further:
- Shortage is calculated, not guessed. It becomes visible next to the schedule, marked per day and resource.
- Free capacity is quantified and highlighted, so shifts can target real gaps.
- Buffer times are evaluated: Which activity still has room, and which one blocks the plan?
- Employees and machines follow the same logic. A bottleneck on a CNC machine is calculated like a bottleneck for a senior engineer.
What Rillsoft does differently: qualification before person
In Gantt tools, tasks are often assigned directly to a person. That is intuitive, but long-term plans then depend on names that may not be final months in advance.
In Rillsoft, each activity can first describe the role and qualification required, for example “senior electrical engineer, 80 hours”. This has two consequences:
- Long-term planning works even before the final team is assigned.
- The concrete person is assigned shortly before execution from the pool of people who fit professionally and are available.
This intermediate qualification layer is the key difference.
When GanttPRO is still the right choice
For one well-bounded project with a small team, a fast overview and no need for capacity logic, GanttPRO can be the better choice. It is lightweight, quick to introduce and focused on visual scheduling.
Rillsoft Project is justified where planning has consequences: delivery dates, staffing decisions and machine allocation. In that environment, the chart must be backed by a calculation.
Strengths in direct comparison
| Question | GanttPRO | Rillsoft Project |
|---|---|---|
| Draw a clear Gantt chart | Yes | Yes |
| Show workload per person | Yes, summarized | Yes, with buffer analysis and conflict resolution |
| Assign employees across projects | Limited | Shared resource pool |
| Qualification-based planning before naming a person | Not the focus | Yes |
| Treat machine capacity like personnel capacity | Not the focus | Yes |
| Choose capacity-faithful or date-faithful planning | Not the focus | Yes |
| Target-actual comparison against baselines | Limited | Multiple reference plans |
More detail: resource planning, capacity planning and multi-project planning.
Who typically moves from GanttPRO to Rillsoft?
Not the single-project planner. Typical candidates are engineering offices where five engineers work on three machine projects, technical service providers whose specialists appear in every second proposal, or industrial companies where project managers compete for the same welder.
In that situation, the Gantt chart is only the visible layer. The real question is who can do what, and when. Rillsoft Project answers that question.
