To measure your DataFitness, look at yourquality, reliability, andperformance
Reliability
Reliability depends on fourfactors:
Backup: Document and test everything.Recovery: How much can you afford tolose?Availability: Are outages "okay?"Security: Crucial for every size business.
Make sure your data isavailable when you needit, even when somethinggoes wrong.
Save yourself problems later bydocumenting and testingbackups.
Don't wait for an emergency tosee if your systems work.

Quality
Quality depends on threefactors:
Accuracy: Calculations produce the sameresults when different systems are used togenerate the data.Cleanliness: Consistency between internal andexternal data entry (i.e. Michigan, MI, Mich) Timeliness: How long from data entry untilaction is needed.
What To Look For:Where can you improve your data entry?How clean is your internal/external datainput?Where can those be improved?Are your MDS (Minimum Data Set) /DQS (Data Query System) systemsworking correctly?
Performance
Performance depends ontwo factors:
Network SaturationSystem Utilization
Network Saturation:
Like a traffic jam on a highway when all lanes arefilled with cars and going very slow.
Or when people are trying to leave a stadium.There might be 10 gates and 2,000 people alltrying to push through.
System Utilization:
The overall usage or health of aserver/workstation (CPU, RAM, HHD, bandwidth,users, connections, etc).
When all those items get close to 90-100%, youget network saturation.
What To Look For:How efficiently are you using yoursystems?How much space are you taking up onyour network?Response time for internal, external, andreporting users.
Evaluating these differentelements will help youdetermine your overall datafitness.
