In the thirty-five years of hands-on experience with the acquisition processes as applied in South Africa, the Middle East, the United Kingdom, the Nordic countries, the USA and Canada on the acquisition of medium to heavy armoured vehicles, it has intrigued the author as to what actually makes the difference between failure and success in executing these supply projects.The underlying assumption of this book was that the required processes are indeed carried out as needed for the various models and that human interaction acts as a catalyst in the process for increased success (or failure) during the typical five to twenty years of the acquisition of armoured vehicles and systems.What is the interactive human enabling factors' contribution towards the success of a project or enterprise during the acquisition phase of a complex system when interacting with a customer The idea of defining a series of interactive events between the supplier and the customer was conceived earlier and has been successfully evaluated in a few projects led by the author. An interactive supply framework was developed from literature and presented in this book.This supply framework consists of two parts:• The executable part of the framework is defined by all the processes required to execute the regular business about the product, the enterprise and the customer. This part of the framework is named the executable factors.• The enabling part of the framework is defined by the human catalytic effect on the normal process; four specific study domains of leadership, relationship, wisdom and culture were considered.These, grouped together, are named the enabler factors. As expected, the forming of professional relationships was identified as having the most significant effect on the successful outcome of the acquisition process.
