Theory Of Constraints (TOC) deals with change for the better and how best to bring about the change.TOC also recognises the output of any system comprising multiple processes,where the output of one such process depends on the output of one or more previous processes and is limited by the least procedure process.TOC sermonises that the goal is making money at present,and for the future.Here "future is as important as "present". Although the profit-earning capability of industry and business would have to be in the driving seat,the means around market and business as a whole were not so complex.These intricasies took an enormous turn during the last two decades,when competition became fierce and globalisation started to dictate the market.Professionals opened their eyes.There was only one buzzword-improve,and make it a continuous process. The book is oriented towards achieving goals starting from the inception of the thinking process as TOC aascribes.The book also provides a thorough insight of managing business even when there are constraints and resolving these by logical thinking.The book is also unique in that it provides the method of initialisation of the thinking process-a dominant feature of TOC. TOC throws challenges to define a goal and asks through a logical thinking process to re-examine all actions and measurements,based on how well or how poorly they serve. - from Amzon
