reworking of lead 

I wandered into this article from dabbawala and had to look below the table of contents to figure out what it is.  I have reworked the lead so the definition comes before the details of who has used it or developed it.  Also, does anyone else notice an unencyclopedic tone (nevertheless non-standard formatting) to this article?  Less management jargon advocacy and more straightforward explanation about what it is and what it is used for would be appreciated. - BT
