Agile methodology took its place, which works iteratively to overcome its predecessor’s drawbacks. Yet again, the industry evolved to look for something more collaborative; agile no longer served the purpose precisely.

I just got an email from a venture capitalist. For about the hundredth time, the venture capitalist told me they were anxious to invest money in us. The only qualification was that we needed to already have at least $10 million in sales. If we had $10 million in sales, we wouldn’t need to be talking with the venture capitalist.
