This is an individual chapter of Theory of Constraints Handbook. Company technique is a reasonably brand-new phenomenon, though people have actually informally been drafting and executing methods of various kinds for thousands of years. In this chapter, the dominant schools of company technique are introduced and briefly critiqued in terms of strengths, weak points, and significant contribution to the field. Also gone over are the requirements essential for an excellent technique along with how technique associates with marketing and sales. Most important is the area on the obstacles of technique and execution with a focus on application, which has actually been noted as the weakest and least developed content location of effective company technique. The chapter closes with some observations on how the Theory of Constraints helps fill important spaces in knowledge of company technique with a particular focus on the TOC contribution to application.
