Pros
Many truly excellent people, particularly at junior and middle levels. Good salaries, competitive with the best. Some extremely innovative product ideas which deserve better exploitation. Some extremely long and successful client relationships (> 30 years is common). A number of charismatic and successful mid-senior managers who could go far (given the freedom and opportunity).
Cons
Large sectors of consultancy market have collapsed with current UK economic turmoil. Detica has adapted to this new reality slowly, painfully and with great difficulty. There is no new strategy to replace that which has gone - 'work harder' seems to be the only management mantra, along with never-ending re-organisations. Insane workload and pressure on staff. Long hours, burn-out common. Redundancy programmes occur yearly, at Xmas (lovely timing). 'Misfits' can disappear at any time. BAe has largely ignored company since purchase (makes you wonder why they bothered), but has now started mindlessly imposing ever more excruciatingly painful business planning, budgeting and other business processes (Detica doesn't make battleships with very long purchase cycles).
