I was at Argos between 2012 and 2013. Fresh out of university. At one point during my time there, for around five or six weeks, me and another graduate were the only front end developers on the entire Argos website. At that stage I don't think I knew the difference between margin and padding in CSS just to give you an idea of our level.
It was truly chaotic. The amount of money they wasted on Accenture consultants should be criminal. I know it's a cliche to say money is wasted on consultants, but really, no work happened. A lot of energy was expended but nothing was built or created.
I was in a newly formed "innovation hub" which had a lot of very talented people but we were blocked from doing anything by internal and external staff at every turn.
One time we tried to have a QA environment set up so that we could demo and test our work. We were told it would take _9 months_ to provision a server for us. We were a team of about 20 in expensive central London office space and we didn't have an environment to test our work. It took about 8 hours to do a deploy to production, so if something was broken the BEST CASE scenario was it would take 8 hours to fix. I never saw the best case scenario.
The most talented and motivated staff in the innovation hub slowly left after we were told that the pace of change had to be "glacial".
Argos never stood a chance of competing against Amazon.
