• Let's suppose that a FTE cost £1/minute.  A tool cost £300.  Over the lifetime of that tool it has to save 5hours of time for that one person.

    Having read "The Phoenix Project" one of the points that hit home for me was that most of a project elapse time is spent waiting for people and/or resource to become available. Saving 1 person 5 hours may actually save considerably more for other people and present the organisation with revenue generating opportunities to boot!  So where is the business case for NOT buying such tools?
    If I was in charge of an organisation with a No 3rd Party Tools policy I would look for the BECAUSE then start looking for the mitigation for the BECAUSE.  There needs to be an internal certification process for such tools.

    Then there is the other extreme where a company buys an expensive tool suite then tries to save money on the training to use that tool suite.  That's got all the wisdom of buying a Ferrari to prevent your garage floor from getting dusty
