eResource Scheduler - Flexible and comprehensive resource management for organizations of any size, including Fortune 500's
eResource Scheduler offers both Cloud and On-Premise versions with configurability & ease of use at core of its design. It’s been used by organizations of all sizes since 2011.
This resource scheduling tool’s features include a dashboard that highlights important information on single screen, along with multiple types of user-defined fields that allow capturing complete information (roles, skills, qualifications, certificates, team, office, etc.) about your projects.
The resource scheduling chart offers resources, projects and role views, and users can create their own scheduling views on the fly. Filters identify qualified resources as per project requirements. Meanwhile, features like drag and drop, availability and overload indicator, extend-shorten, precise split, copy-paste make scheduling efficient and quick.

TeamGantt - Easy-to-use online Gantt chart software with a simple read-only sharing link for quick collaboration and update opportunities
Used by Amazon and Netflix, TeamGantt is a project management tool with resource management functions like time- and budget tracking in the availability tab. TeamGantt specializes in task planning tools and charts but they also track workloads and team availability, collaboration features like chat and tagging, and customizable alerts.
One con with TeamGantt is that dashboards’ views sometimes lag behind real-time changes to resource tracking. Resource-complex projects may lag a bit due to the fact of TeamGantt being an in-browser, cloud-based application.
TeamGantt scores well in the Usability segment of the evaluation criteria, as it is incredibly flexible to use. The tool is accommodating to however you may want to set up and track your projects, no matter their resource structure or constraints. Additionally, providing an easy “read-only” URL makes it great for sharing with outside parties for input.
TeamGantt costs from $24.95/month and has a freemium version of the software for up to 3 users.
- Flexible setup/tracking for projects
- Share charts without receiver logging in
- Easy drag-and-drop task duration
- Quick learning curve
- Dependency data is awkward at times
- Lack of in-app notifications
- Views can lag behind changes
Microsoft Project can be clunky (which is why many people search for MS Project alternatives), but MS Project is still a standard, well-supported, and widely adopted tool. It includes familiar scheduling tools to assign project tasks to team members and use different views like Grid, Board, and Timeline (Gantt chart) to oversee the schedule. Users can view and compare how resources are used across projects to optimize assignments.
If you are familiar with other Microsoft programs, in particular Excel, then the interface and navigation will be familiar to you. This can help teams on a Usability level, as familiar software makes for easier training; thus, they evaluated well in Usability in this regard.
Integrations include other Microsoft software, like Outlook, Excel, Skype, and more.
A few critiques that would make this solution better for resource scheduling is that you can’t open different projects across different windows (for, say, easily comparing resources between the two) and PDF exports look messy, so if you use them for reports or printable projects you will need some manual design intervention.
MS Projects costs from $7/user/month and has a free 30-day trial.
- Can generate a Gantt chart from a spreadsheet
- Helpful project template descriptions for guidance
- Driver prioritization module for ranking strategies/objectives
- Integration with other Microsoft software
- Limitations on collaboration tools
- Higher learning curve
- Few customization options
