This is NOT good advice. This would turn management by objectives into fanaticism. The worst examples of this proclivity for absolutism come from religious fundamentalism and political messianism, but technophoria obviously has similar strains in it. The remainder of the book reflects this uneven advice. This is premised on the profound illusion that consistency counts.
Various tasks require different methods, so the only wise policy is methodological pragmatism.
If project sponsors had the good sense to invest in properly trained implementation personnel, the likelihood of success would increase dramatically. The real challenge of experienced project management is delegation and deadlines. Work plans, like workflows, only give value through the actions they facilitate. I DO recommend this book, because the good advice is VERY good. As for the bad advice, replace it with your own better judgement.
