Can somebody recommend a book on Strategy Planning and Analysis?

I pass this Strategy Planning and Analysis course when I was in B-School. Now I am going for some corporate finance jobs and need insights on this field. Can someone recommend a book on this to me? Thank you in advance.

I used this book in b-school and found it very useful. Exploring Corporate Strategy: Text & Cases 8th Edition Gerry Johnson Kevan Scholes Richard Whittington

In addition to Johnson & Scholes, check out Tompson and Strickland…can remember the edition but combined with J & S makes beautiful pair to sort you out clean
