Why are large companies so difficult to rescue (regarding bad internal technology)link

There are two big problems that plague rescue efforts at big companies: history and trust…

All of which helps explain why technology rescues at bigger, older companies are so difficult. One is constantly fighting against history…To a large extent “be agile” is almost synonymous with “trust each other.” If you’re wondering why large companies have trouble being agile, it is partly because it is impossible for 11,000 people to trust each other the way 5 people can. That is simply reality. Until someone can figure out the magic spell that allows vast groups of people, in different countries, with different cultures, speaking different languages, to all trust each other as if they were good friends, then people in the startup community need to be a lot more careful about how carelessly they recommend that larger companies should be more agile.
