When you're ready to scale your team up (or down), just let us know and we will be happy to assist. If requesting a new team member, you can add the additional role to your existing team spec. We will then work with you to align on the specifics regarding role requirements and you will undergo the same process as before (proposal review, interviews, if necessary, kick-off and deployment).
Luckily, removing a team member is also easy. All you have to do is let the team member know that your engagement is coming to an end, and work together to come up with a mutually agreeable off-boarding plan. We can then assist in replacing them or simply ending their engagement with you.
