Answer:
B) business portfolio analysis
Step-by-step explanation:
The Boston Consulting Group uses its BCG Matrix (AKA Growth/Share Matrix) to analyse a company's brand portfolio in order to determine possible long term strategic plans. Strategic planning should help the company achieve its growth potential through a process that reviews its product portfolio and divides them into: question marks, stars, poor dogs and cash cows.
This way the company can decide where to invest, which products to discontinue, and which products to develop.
