Microsoft Project Alternative: When the shared resource pool is the real problem

Microsoft Project has been a standard tool for classic project planning for decades. Activities, dependencies, critical path and Gantt charts are familiar and solid. Organizations rarely leave Microsoft Project because of single-project scheduling.

The trigger is usually the multi-project case. Once the same employee appears in several MPP files at the same time, the pain begins, and the Microsoft answer often points toward a server architecture that can be oversized for mid-sized companies.

Three paths, three pain points

Microsoft offers several paths into multi-project planning. None is automatically ideal for mid-sized industrial companies.

Path 1: Shared resource pool as an MPP file. This is the classic approach. In practice, a central MPP file is linked to several projects. Parallel access, missed updates and fragile master data can become recurring issues. The architecture was not designed as a modern multi-user planning database.

Path 2: Project Online / Project Server. Technically capable, but often an implementation project of its own: Microsoft infrastructure, per-user licensing, configuration work and reporting setup. This can make sense in large organizations, but can be too much for companies with 60 to 150 employees.

Path 3: Project for the Web. Modern and easier to deploy in Microsoft 365, but positioned differently. A full resource pool with qualification filters, machine capacity and target-actual comparison against several baselines is not the center of that product model.

In all three paths, the core issue remains: the resource pool is an add-on layer, not the center of the application.

How Rillsoft solves the pool question differently

In Rillsoft, the resource pool is not a shared file or a server-side add-on. It is the central data structure around which planning is built.

  • Several project managers can plan in the same database without file-locking workarounds.
  • Utilization is current because changes in one project affect the portfolio view immediately.
  • Qualifications and roles are first-class data, not just notes on a resource.
  • Machines are treated like personnel with calendars, availability and utilization calculation.
  • Site-related allocation can support distributed teams and location-based analysis.

Target-actual and controlling: where classic planning becomes too loose

Microsoft Project can work with baselines, but in many teams the comparison logic remains manual and difficult to maintain. Rillsoft Project works with multiple reference plans that remain structurally comparable.

Schedule, resource and cost deviations are shown graphically and in tables. Financing and liquidity control can add a time-based comparison of cash inflows and project costs, which is outside the core focus of Microsoft Project.

Where Microsoft Project remains the better path

For pure single-project planning, organizations with a mature Microsoft stack, established MPP templates and external partners who expect MPP files, Microsoft Project can remain the natural choice.

Rillsoft does not compete primarily in that niche. The difference becomes visible when cross-project resource control is the central issue, which is common in mid-sized industrial planning.

Data sovereignty: your own database instead of Microsoft 365 lock-in

The route into multi-project planning leads through Project Online, Project Server or Project for the Web, and therefore into the Microsoft 365 and Power Platform ecosystem. The planning data then resides where the vendor’s licensing model and infrastructure apply.

Rillsoft keeps project and resource data in its own database, either on-premise with the Rillsoft Integration Server in your own infrastructure or as Rillsoft Cloud with server location Germany. Data sovereignty stays with the company, and the operating model can be chosen freely without changing the planning logic. For mid-sized industrial companies that do not want to couple their project data to a cloud ecosystem, this is a selection criterion in its own right alongside the pool question.

What remains familiar, what becomes new

Familiar:

  • Activities, durations, effort, predecessors and critical path
  • Gantt chart as a central planning view
  • Milestones, activity types and constraints
  • Excel import/export and MS Project import

New:

  • Real central resource pool without heavy server architecture
  • Qualification-based activity planning
  • Choice between capacity-faithful and date-faithful planning
  • Machines and personnel in one planning logic
  • Multiple reference plans with structured target-actual comparison
  • Site-related allocation for distributed teams

More detail: resource planning, capacity planning and multi-project planning.

Typical switching scenario

An engineering office with 80 employees, 12 parallel projects, four Microsoft Project licenses for project managers and a central Excel sheet where management maintains utilization. Maintaining that sheet costs days per week. Moving to Rillsoft replaces that spreadsheet with a calculated view and addresses the unresolved resource-pool issue.

Frequently asked questions(FAQ)

The classic resource pool in Microsoft Project Desktop is a shared MPP file used by several projects. In practice, this can mean file locks, manual updates and fragile maintenance. Organizations that need a real multi-project resource pool often move toward Project Online or Project Server, with the associated license and infrastructure complexity. Rillsoft focuses on a central pool without that enterprise server layer.

They address parts of the multi-project gap, but remain tied to the Microsoft 365 ecosystem, licensing model and platform logic. Companies that want a specialized planning tool instead of a composed Microsoft 365 architecture may become productive faster with Rillsoft.

Users familiar with Microsoft Project will recognize activities, durations, effort, predecessors, milestones and the Gantt view. What is new are the layers above that: qualifications, a cross-project resource pool, capacity-faithful versus date-faithful planning and more structured target-actual comparison.

Yes. MS Project files can be imported. The structure of activities, dependencies and durations can be used as a basis. The resource layer is usually set up cleanly in Rillsoft because it is organized around qualifications and a central pool.

Rillsoft can export to MS Project. External partners who require MPP files can receive them. Internally, the source of planning truth can remain in Rillsoft with a working resource pool.

Microsoft Project licenses plus optional Project Online or Project Server scale with the number of users and the chosen environment. Rillsoft uses a structured edition and license model in which not every employee needs a full planning license. Concrete comparisons depend on user count and operating model.

Project Online, Project Server and Project for the Web build on Microsoft 365, SharePoint and the Power Platform, so the planning data lives in the Microsoft ecosystem. Rillsoft keeps project and resource data in its own database. Companies that want to keep data sovereignty and freedom of operation can run Rillsoft on-premise or as Rillsoft Cloud with server location Germany, with the same planning logic.

Yes. The Rillsoft Integration Server can be operated on-premise in your own infrastructure; alternatively, Rillsoft Cloud is available. The edition and planning logic of the desktop client does not change with the operating model.
