The purpose of a business, while being true to a noble, clear, focused mission, is to attract, serve, satisfy and retain customers with ever-improving — and new — products and services, executing effectively, efficiently and ethically, thereby allowing employees and investors,
suppliers and other stakeholders to prosper.
(Hospitals, colleges, other not-for-profits and governmental units may substitute above —   patients, students, clients, citizens — and contributors, taxpayers and volunteers, as appropriate.)

Be easily accessible to customers, not only in the sales process, but afterward with installation, repair, returns, billing and other issues.

To accomplish the purpose, fulfill the mission, of the organization, employees, managers and executives must be carefully selected, appropriately placed, fully trained, regularly recognized, fairly treated, justly compensated and well led.

Organizations and reorganizations are always some combination of these basic structures

• customer groupings (e.g. business, consumer)
• functions (e.g. accounting, sales)
• products/services (e.g. women's clothing, auto body repairs)
• geography (e.g, Southwest region, Rockland branch).

To be most effective, organize or reorganize from the customer in, the bottom up.

Introduce new and improved technologies, systems, processes, products and services as rapidly as possible — consistent with mission and current strategies — and only in such a way to maximize benefits to customers, employees and others and to minimize their pain.

When in doubt, reread the first paragraph.
