The Story behind the Succinctly Series
of Books
Daniel Jebaraj, Vice President
Syncfusion, Inc.
taying on the cutting edge
As many of you may know, Syncfusion is a provider of software components for the
Microsoft platform. This puts us in the exciting but challenging position of always
being on the cutting edge.
Whenever platforms or tools are shipping out of Microsoft, which seems to be about every other
week these days, we have to educate ourselves, quickly.
Information is plentiful but harder to digest
In reality, this translates into a lot of book orders, blog searches, and Twitter scans.
While more information is becoming available on the Internet and more and more books are
being published, even on topics that are relatively new, one aspect that continues to inhibit us is
the inability to find concise technology overview books.
We are usually faced with two options: read several 500+ page books or scour the web for
relevant blog posts and other articles. Just as everyone else who has a job to do and customers
to serve, we find this quite frustrating.
The Succinctly series
This frustration translated into a deep desire to produce a series of concise technical books that
would be targeted at developers working on the Microsoft platform.
We firmly believe, given the background knowledge such developers have, that most topics can
be translated into books that are between 50 and 100 pages.
This is exactly what we resolved to accomplish with the Succinctly series. Isn’t everything
wonderful born out of a deep desire to change things for the better?
