Designing and installing an information system is a challenge. It easily fails if we omit thinking before acting.
Everyone knows that thinking must be put before acting. But s/he fails in practice.
The reason why it happens is that they miss the content of thinking. Specifically, the methodology of information system design is lacking.
The most important components of this methodology are the understandings of the followings : (1) ends of information system expressed by the words of "user experience", (2) speciality of the organization, (3) meaning/situation of diversity of individuals, (4) culture/tradition of the organization, (5) advantageous features of the system.
As to (4) culture/tradition of the organization, the following shift becomes required : diversity-oriented, break off conservative tradition, paper-document-based, "if we build it, they will come."
The points of practice are "minute thinking", "starting small, making it pay off", and user support (induction, training), setting aside other matters of course.
