One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code.

Take 'Market Insight', one of BLM's major modules, for example, which is also what everyone understands as' Market Analysis and Evaluation '. Its use in formulating company strategy and product line strategy is completely different, which is related to the different levels of concern of company strategy and business strategy.

Therefore, when analyzing the market opportunities at the company level, the focus is to analyze the attraction and competitiveness of the industry environment in which each business is located, and to analyze the strategic positioning of each business and the business combination strategy that the company should adopt. The business strategy focuses on which target market segments should the business develop in? How to develop? What measures have been taken to promote development?

In order to succeed in the market segment, the 'market insight' needs to further analyze the pain point needs of the main competitors and target customer groups in the market segment, but these analyses are not the key content in the 'market insight' at the company level.
