The difference between strategic planning and business planning

So what’s the difference between strategic planning and business planning? There seems to be some confusion and/or disagreement about the answer. I see the two processes as related but very distinct. Here are three articles that shed some light on the subject. The first article is “Business Planning and Strategic Planning Revisited” by Herb Rubenstein of Growth Strategies, Inc., a leadership and management consulting firm. Go to: http://www.refresher.com/!hrrrevisited.html. The second article is “Strategic Planning: Some Lessons Learned about What Does and Doesn't Work” by Paul Connolly of the TCC Group (formerly The Conservation Company). Go to: http://www.tccgrp.com/pdfs/per_art_stratplan.pdf. The third article is “Business Planning for Nonprofits: Why, When — and How It Compares to Strategic Planning” by Brigette Rouson of the Alliance for Nonprofit Management.
