Think in terms of a multi-purpose hall, giving different teams and different sub-teams the ability to modify the box to fit their needs so they can hear themselves and each other better.
The Shariah black box is yet another financial fad like the sub-prime market where transparency is shrouded in opacity in the mad rush to market-share and quick profits.
If it is unable to either shift from the big-box retail format to smaller stores, or optimize store space by sub-leasing to other businesses, operating costs will not come down.
