Wimbledon's roof policy

The Wimbledon Championships are a good opportunity to look into how other businesses are building and operating their processes. Last week's matches have triggered discussions around the Wimbledon roof policy.
• Time to close the roof in Halle (german grass tournament) : 88 seconds
• Time to close the roof and resume play in Wimbledon : 40 minutes.

As a possible explanation you will be tempted to think that the stadium in Wimbledon is much bigger. Not really, as 15'000 seats expand »instead of 12'300 seats. So where is the trick?

It boils down to the business requirements. The Business Analysts in charge to capture the Wimbledon roof requirements had to consider several additional challenges in comparison to the Halle roof :
• The unpredictable London weather
• The extension of play with lighting in the evening
• The recreation of an outdoor atmosphere via the air management system

• Things should be quick and simple: a new roof should be closed in 5 or max. 10 minutes
• Things should be logical : open the roof once the weather is again sunny

• The header says ‘Murray backs roof policy’ but the detailed text says ‘Wimbledon's Centre Court roof policy is still very much a work in progress’
