I need to link the Unfreeze, Freeze, and Refreeze model to a real case of a bank that wanted to change its IT system but it was a failure because of :

- poor leadership

- unclear communication about the project and the strategy (they had planned reducing costs without mentioning it during their conference with the staff) they started closing branches without noticing customers and employees found themselves without workstations just hanging there.

- departure of a lot of senior managers including the CEO, human resource manager was changed 3 times and a lot of employees dismissed for other jobs.

applying the unfreeze, freeze and refreeze model, how this bank should have handled this organizational change?

Please I need detailed explanation not only bullets.

Thank you
