Seven wastes and software or development wastes

Defects (the effort involved in inspecting for and fixing defects)

Overproduction (making more than what is needed, or making it earlier than needed)

Transportation (moving products further than is minimally required)

Waiting (products waiting on the next production step, or people waiting for work to do)

Inventory (having more inventory than is minimally required)

Motion (people moving or walking more than minimally required)

Processing itself

• Hand offs

• External quality enforcement

• Waiting

• Transaction waste

• Reinvention waste

• Lack of system/scheduling discipline

• High process and arrival variation

• System over utilization (80% capacity)

• Large batch sizes

• Redundant tasks

• Stop and Go tasks

• Unsynchronized concurrent tasks

Principles of lean design in IT

• Exception based management

• Real time information

• Ubiquitous access

• Push based principles

• Portal for operations

• Standardization as foundation for improvement

• Only experts are allowed to break rules

• Application may be complex, usage should be simple – Do not ask for complex usage to make the application simple!

• It is vital to distinguish “data” from “information”
