On an average we code only about 5% of our working day other 95%On an average we code only about 5% of our working day other 95%
we arewe are
– Reading code (understanding other people's code)
– Testing
– Understanding Requirements
– Communicating with colleagues
– Building and Releasing
– Problem Solving (Analyzing and Designing)
Knowing a language, knowing how to code, having a
college degree does not make you an Engineer...

Software Engineering practicesSoftware Engineering practices
– Why are we doing software - To meet a client's need?
– Keep it simple (KISS)
– Know that you only write once but others will consume
what you produce (coding standards / clear coding..)
– Be open to the future
– Plan ahead for re-use
– Think and then act (not the other way around)
– Design principles and practices – (SOLID / OOD ...)

Try new tools, learn about tools, how to use existing tools (even
when you do not need to use them like IDE tools, profiling tools,
