Its scalability is beyond a perfect ten; it's incredibly and impressively scalable.

Planisware scales effortlessly when hosted on decent Linux Server(s) with ample RAM and sufficient CPUs. 

In a SaaS environment, what Planiware determines is adequate performance by sevice level agreement may not align with your company's users over time. Planisware can upgrade servers your organization uses after appropriate negotiation. 

I don't see any challenges with the scalability of Planisware. I haven't seen scalability as an issue with Planisware during the six to seven months of the rollout we have done. Currently, around 5,000 users are using Planisware in our organization.

We have more than 100 people using the solution in my organization. We do not plan to increase our usage over the next year.

I rate the scalability of Planisware a six out of ten.

What are your impressions of the stability of this solution?

Stability for SaaS environments is excellent. Most cases of stability problems traced back to incorrect data, such as schedule dates that are impossible in the real world. Identifying and fixing bad data resolved stability issues about 80% of the time.

Planisware is a highly scalable solution.

It is all managed through a contract. There is a process, and the client cannot add licenses or new users. There are a defined number of licenses that are sold to the client, but in terms of scalability, as far as I know, there are no limits related to the number of projects, etc. There can be an enormous amount of projects. It is just the process that defines the rights and the responsibilities of the users.

Not really. The solid data model, and selection of state of the art servers has guaranteed very decent system performance. Users located across Europe, US, and Asia continue to enjoy stable and equal performances.

The solution is scalable.

We have one department using this solution and it has approximately 50 users.

I did not encounter any scalability issues.
