T-shaped, pi-shaped, MBS-shaped?

It's not a good sign when things go pear-shaped.
But what about if things go T-shaped?
Pretty good, according to Minister of State for Manpower and National Development Tan Chuan Jin.
The T-shaped individual is one who combines a deep skillset with a flexible mindset brought about by a broad big-picture understanding.
And that is the key to advancement in our fast-paced rapidly changing world. But as CSC's Mr Aaron Maniam says, just a T may not be enough. Individuals need to have a deep insight into more than just one field of expertise, he says. In other words, pi-shaped (with two "legs" of knowledge rather than just one) may very well be the standard, moving forward.
In fact, he joked, alluding to the architectural design of the iconic Marina Bay Sands resort, we may have to aim towards getting an MBS-shape in the future!
As long as things don't go pear-shaped in the process, I say.
