For some, this is the consulting version of Siberia; lost in a hopeless no-man’s land. Without a plan, you'll have very little to do and what you are assigned is often either busy-work or unfulfilling at best. Like a utility player on a sports team, you are sitting in reserve waiting until your skills are needed for another project. It doesn't have to be this way tho. Here are some of the things that you could be doing:
1) Self-promotion: make sure folks know what your interests are, and the sales team know what style of engagements are appealing to you. When was the last time you took an account manager out for coffee or ran a knowledge sharing brown bag? Did you learn something cool yesterday? Run a brown bag or author a thought piece.
2) Helping out: Use the standup to signal that you want to pair with folks. Your peers, state and national leadership teams have a bunch of things they always need help with. Consulting typically involves aspects of leadership, and that can be tiring. Recharge by helping others achieve their goals. It's quite rewarding.
3) Shipping: Create something small, ditch all of the traditional best practice guidelines such as test-driven development or CI and hack away in notepad on a web-server. Get your idea live by the end of the day - i.e. https://noyaml.com/ Taking something from concept to production in a short period is a rush, and I find that the energy compounds. Done right you'll have something to do a brown bag on or show at the next standup.
