There’re projects with the total time from idea to implementation is up to a few weeks.
The size of the project can affect the timing. A small process can take 2 weeks of development and 2 weeks of testing before deploying to a production environment. Likewise, a medium-sized process can take 6-8 weeks after being put into production. In the case of a large process, this can take 4-12 months after starting production. A typical example of this is when a process is introduced as an initiative to eradicate or reduce a manual process to a significant number. This takes a lot of development time, testing, and most of the time until the SME client/enterprise is fully satisfied with such a process.
It's much faster than most IT projects - RPA is usually fast to deploy and fast to get benefits from.
