... The folks at Kodak made many bad decisions. How and why?..
From my perspective (I spent about two years with them), several factors. One would be: being an old company, there was a lot of fossilized bureaucracy. Then short-termism: obsession with quarterly results and "my" bonus - i.e., hasty decisions were made that look good in one quarter and got that manager a bonus for that quarter (or year-end), while consequences would be felt in the next period(s). By the time the mistake shows up, the manager might have been rotated through several other departments - there was an obsession with inter-departmental rotation, the consequence of which was that a lot of inexperienced and unqualified people got to manage things they did not fully understand. Again, being an old company, there was a lot of the "old boy club" mentality, "that's the way we do things at Kodak."
The thing that surprised me the most was that I was the only one among the management with a decent understanding of... wait... photography. Almost all others were typical salesmen and marketeers, whose knowledge of photography did not exceed the disposable cameras Kodak was peddling at the time. I am, of course, not talking about research and development departments. So, when I told my boss, a country manager (an American), back in 1999 that digital would take over in five years, he brushed it off as a distant future. Had he and others at his level (pretty high in Kodak's hierarchy) had a bit more advanced understanding of photography, he would have seen the same thing I did. Then again, when you are obsessed with this quarter results only, you develop a myopic view of the future, and can't see even the next quarter, let alone the next five years.
