Order book without execution has no relevance!

Market continues to be fixated with order wins for companies, forgetting the fact that infra & capital goods companies had massive order books even during the 2007 bull run but when the market crashed, those order books were of little help in sustaining the high valuations. A healthy order book matters no doubt, but one cannot ignore the fact that execution matters too. And if the execution goes awry, it will have an immediate impact on profitability. What will you do with the order book unless and until it gets converted into cash?
