Human aspects of change - lessons from the U.S. Army and Elisabeth Kubler Ross
Conclusion: Most major IT implementations such as ERP roll-outs, do not fully realise their original objectives. One symptom is that planned functionality is not utilised by staff to the fullest extent. Another is a tendency for staff to fall back to their comfort zones, using manually-maintained records, spreadsheets and the like. The root cause is that insufficient attention is paid to dealing with the human aspects of change. Knock-on effects are largely financial. If additional resources need to be brought in to effect lasting change, this action dilutes the strength of the original business case, not only in terms of outright cost but in the time taken to achieve desired outcomes. If left untreated, the full benefits may never be realised.
