Depending on what firm/s you want to get into I would actually say your experience far outweighs having either an ACA or some frankly pedestrian qualification like Six Sigma (more of a tool than a complete method). I don't see you fitting into an operational team though - more a commercial strategy outfit, perhaps with a TMT focus or a little broader. Firms like Greenwich Consulting, Ocean, mmcGroup, Analysys Mason etc - more concerned with the issues you have been working on, rather than ground floor ops improvement, which is a different animal.Rec firms won't be able to assist in this current market I'm afraid: we are focused on finding very precise fit for often very specific roles currently, so we don't have the wriggle room we enjoyed 6 months ago. My best advice is to stay put if you can, get more experience -especially if you can get some sort of project shape to what you're doing and look at this move again later this year: we are seeing some confidence return, and hiring pipelines becoming a little firmer again, but it will be a while before consulting firms feel they can gamble on unproven hires from when there is plenty of consulting talent available.
