How often do you meet?
Daily (usually first thing in the morning), and whenever necessary to remove roadblocks. Pairing only when necessary to solve complex problems - or early in test development.
Have you tried different sprint lengths (one week, two week, longer) ?
Yes, but this always depends on customer-provided priorities and delivery schedules first. We respond to their requirements, not make up our own. Sometimes spikes play into this, as it is impossible to avert dependency loops.
Which tools do you use?
Pivotal Tracker and Rally. Have been forced to use TeamForge, which sucks. I really like Campfire and it seems to do the trick for my teams.
Which issue tracker do you use?
Depends on the project, but usually something that is web-based at a minimum.
What do you do about time zone differences?
Deal with it. Most of my projects are spread around the world, somebody is going to get screwed - it usually is me.
How does it work for you to integrate new people into the team?
Depends on the team, and the newbie. Some teams are more accepting than others, and some newbies are better at integrating. There should always be respect, period.
How many hours do you usually work per week?
40+ - the plus usually is due to multiple projects - pro and personal.
How does your management interact with the way you are working?
Hands-off. But, sometimes things get tense. Just takes good communication, and transparency is always better.
Do you get put on a waterfall with hard deadlines?
Sure...even within Agile projects. Customers are demanding.
What's your unit of work?
Depends on the project of course. But, usually time for me and my teams. Deliverables go with everything...but we usually have up-stream projects to support too.
What is your normal velocity? (units of work done per week)
There is no normal. Complexity, team, customer all play in as rough variables. The biggest problem is usually team maturity.
