9. INFORMATION
Let’s talk about
TIMELY
It must be
7 characteristics to judge its value
#2
• Has an age suited to its use - it’s
always up to date!
• It is available in time for its use
when needed.
• E.g. a weekly sales report should

10. INFORMATION
Let’s talk about
RELEVANT
It must be
7 characteristics to judge its value
#3
• Needs to be within the context and
subject of the system.

eliminated!
11. INFORMATION
Let’s talk about
JUST SUFFICIENT
It must be
7 characteristics to judge its value
#4
• Output should be just enough for
its intended purpose.
• Systems should be smart enough
to only display information that is
relevant to specific users.

summary rather than a detailed
report; or a lecturer would not
require your hobbies when taking
your attendance.
12. INFORMATION
Let’s talk about
COST EFFECTIVE
It must be
7 characteristics to judge its value
#5
• Important: data is not free. It always
comes with a cost.
• Cost can be for operations and
system maintenance, users’ time,
salary or convenience.
• A good system is able to produce
information lesser than the actual
cost of the data, i.e. to create value!
13. INFORMATION
Let’s talk about
VERIFIABLE
It must be
7 characteristics to judge its value
#6
• Users should be able to confirm
and verify the information
presented in the system.
• It should be auditable with a clear
trace of data.
14. INFORMATION
Let’s talk about
ORGANIZED
It must be
7 characteristics to judge its value
#7
• Information should be arranged to
suit the objectives and needs of the
business / users.
• It can be in the form of tables,
reports, diagrams - any output that
makes sense!
