THE SPEC
DESCRIBE HOW THE SITE WORKS

FROM THE USER’S
PERSPECTIVE

CHANGES ARE
CHEAP
TO   MAKE   ON

PAPER
ENABLES EFFICIENCY!

      - CAN BE -

  PLANNED
 UP FRONT

SURPRISES
2
    EVALUATE POSSIBLE
EXISTING SOLUTIONS
DON’T

REINVENT
THE WHEEL
EVALUATE AGAINST
    YO U R ( N OW S O L I D )

SPECIFICATION
CONSIDER COMPROMISES:
WHERE DOES COST MATTER


MORE
THAN FEATURES?
USE EXISTING CODE AND BUILD


10% ON TOP

100%
FROM NOTHING

CONSIDER THE COST OF YOUR
DESIGN CHOICES

EVERY

UNIQUE ELEMENT

  REMEMBER: BROADBAND IS
NOT A SILVER BULLET
D E S I G N I N G F O R B R OA D BA N D P U T S

EXTRA LOAD
ON YOUR SERVERS

EXPENSIVE
CONSIDER YOUR

        TO ADAPT IT

 BUILD YOUR SITE FOR LOW COST
QUALITY ASSURANCE
       (THAT’S TESTING!)
EVERY ELEMENT OF A SITE

NEEDS TO BE TESTED

 QUALITY SUFFERS
CONSIDER THE

TESTING OVERHEAD
  OF EVERYTHING YOU ADD

BUILD ON THE SHOULDERS OF GIANTS

USE EXISTING APIS
