Observations on Steve Job's legacy - and Apple's leadership future - are only just beginning. In recent years, many leading thinkers have contributed their thoughts on the Jobs phenomenon on HBR.org. We've compiled a few of the most insightful here, and we invite you to read them through the lens of business lessons to be learned. We've selected six pieces: two from after Jobs's August 2011 retirement and four from before. We hope you will enjoy them, learn from them, and continue to turn to HBR.org for ideas and inspiration.
