With the upsurge of learning various management experiences from Huawei in recent years, The BLM (Business Leadership Model, commonly known as "Don't Touch") model introduced by Huawei from IBM for 30 million yuan in 2006 has also been hotly discussed by the business and management consulting circles. However, at present, the vast majority of online information on BLM is only at the level of brief introduction. There are two kinds of BLM translations, one is the "business leadership model" and the other is the "business leadership model". The difference between the two translations reflects the difference in the specific application of this set of tools. The former regards it as a strategic planning tool, while the latter uses it to enhance the leadership of middle and senior managers. IBM's original intention in introducing BLM to Huawei was to unify the strategic thinking methods and framework of Huawei's middle and senior managers and to enhance their leadership, because managers' leadership was gradually cultivated in the process of formulating strategic plans and promoting strategic implementation. In the subsequent actual use of this tool, It was found to be an inclusive thinking framework, It can integrate various tools previously used in strategic planning, such as MM (Market Management) of IPD (Integrated Product Development), strategy decoding, strategy map, balanced scorecard, etc. into it. And can use this thinking framework and strategic language from the company strategy to the business unit strategy and then to the strategy of each functional system.
