Hi AnonI dont work for the SI Practice but have worked in Assisgnments led by them - So my answers might not be totally accurate but will try my best :Most of the work we do is in what you have called the "Project Management side" but which can be clubbed into "Advisory Services" - SO things like creating Business Cases, helping clients draft RFPs, taking them through the Procurement and Sourcing cycles, Vendor Selection , helping them through the Design and Architecture stage and so on. We have a proposition caleld the "Solution Builder" where we handle Development and Implementation, though this is still a new theme but is growing quite rapidly. I dont think you will have trouble from moving from one "side" to another , as a lot of people in SI do that. Promotion timescales that you have mentioned are very close to reality - Within 3-4 years, you can expect to move from Analyst to ConsultantBonus - I cannot comment on this as I have only joined PA this year. I was in a Big-4 Consultancy and moved to PA early this year - I must say I have been impressed with them and am happy I made the switch - Great people to work with, Great projects and hopefully I will get a decent bonus too.Good Luck to you
