/goes back to slog with the estimation calculation

But the problem facing such an idea is the lack of concern for an all-round development of employees in most of the present-day companies.

You can definitely work on such an idea in a start-up or your own company, however in alomst every well-settled organisation, the core values and visionary statements may vary, but the bottom line always intents extracting the maximum effort from the employee in order to make the targets/deadlines meet. Means of trainings and personality development do exist, but the primary motive behind them is also to make the employee skilled further for the primary job at hand.

Just my 2 cents..

Sorry for blatant self-promotion, here is the reason.

At 12 million tweets a day and growing rapidly, nobody can pull all that data out of Twitter.

I think, Twitter search can be as big as news search.

The places which made you wait, were the solutions (not engineered but desired), to be primarily low cost leading to over provisioning. Just an example mobile operator here over subscribes the capacity over the air around 20-50 times. They expect all the subscribers will not call at the same time. This overprovisioning is always there, but here the low costs are driving this fact or oversubscription to crazy limits.
he dsl backhaul infrastructure is oversubscribed around 5 times. We make the router. To make one link more reliable, despite making better s/w and h/w, we provide n:1 redundancy where N can be 1-5. We know that customers in US will always configure average redundancy, and intentionally waste the capacity (whole line card and the link both).

Take the example of datacenters, the ones which are required for any centralized information processing like banking, railways or aviation which made you wait. The factor of HA and reliability increases the cost significantly right from the enterprise side resources ( end point) to network connectivity to the server farms. When they say server is down, it could be cost cutting into anywhere in this chain. Take the cast of google or facebook, one query on the Internet is posted to around 50 servers in parallel leading typically upto 50 different locations. Thats why on google you rarely see the server is down. Yes in order to accomodate this, the s/w, h/w and system desgin also has to support this and its not purely a function of building more capacity, but cost (as seen by enterprises) is more impacted from more network elements and less from higher quality s/w running inside them.

So the IT solutions and infrastructures that have made you have suffered from, party is because of bad design. But in majority cases when impact is this big as you are talking about - waiting for hours, its about making the cheap choices in deployments.
