How to improve the quality of our IT Services? How can you contribute?

continuously improve service quality

Where are we now?

Current process & procedures

Current challenges & problems

Where do we want

to be?

What are the priorities?

How do we bridge the gap?

How do we get where

we want to be?

Informed planning

Experienced execution

Are we improving?

Did we get to where we wanted to be?

Strict control

Status communication

Continuously Improve Service Quality

How do we keep the

momentum going

how to get there quality improvement model
Deming Circle (PDCA)

Plan: Plan ahead for change. Analyze and predict the results.

Do: Execute the plan, taking small steps in controlled circumstances.

Check: Study the results

Act: Take action to standardize or improve the process

How to get there - Quality Improvement Model
itil philosophy three process
ITIL Philosophy Three - Process

“A process is a specific ordering of work activities across time and space, with a beginning and an end, and clearly defined inputs and outputs: a structure for action. ... Taking a process approach implies adopting the customer’s point of view. Processes are the structure by which an organization does what is necessary to produce value for its customers.”

- Thomas Davenport, “Process Innovation”

characteristics of processes
Characteristics of Processes
  • Definability: It must have clearly defined input and output
  • Order: It must consists of activities that are ordered by time and space
  • Customer: There must be a recipient of the process’ outcome
  • Value-adding: The transformation taking place within the process must add value to the recipient
result vs process
Result vs. Process
  • Result Oriented Management
    • Results can map to Activities
    • Results are measurable and worth measuring
    • Only applicable for low risk task
  • Process Oriented Management
    • Define a process to achieve the result
    • Break down the overall result into smaller intermediate results
    • More control and lower risk
why we need process to provide high quality service
Why we need Process to provide high quality service?
  • Service
    • Intangible: Customer Experience
    • Interactive: One-time, Cannot be stored
  • Process can help
    • Consistent performance
    • Reduce risk
    • Repeatable: Customer experience can be repeated next time
but what does process mean to me

Understand the whole picture

Know what to do in any circumstances

Clearly defined Roles/Responsibilities

Measurable performance

Save time and efforts


May change way we used to carry out our tasks

Take away some flexibilities

But, what does process mean to me?
itil philosophy four measurement
ITIL Philosophy Four - Measurement

If you cannot measure it, you cannot manage it

If you cannot measure it, you cannot improve it

If you cannot measure it, you probably don’t care about it

If you cannot influence it, you don’t need to measure it

what do we mean measure here
Check in PDCA

Evaluate if we are in the right direction?

What do we mean “Measure” here?


Are we in the right direction?

Start Point

why best effort is not good enough
Why “Best Effort” is not good enough?
  • “Best Effort”, “Some Progress”, “Improved Performance”… are not measurable.
  • “Performance is improved 10%”, “Time to Market decreased from 100 days to 50 days”, “Customer Satisfaction Rate improves 23 percents”. Those are good measurements.
  • All the measurements must be quantitative!
what to measure
What to measure?
  • Goal (Where do we want to go? What are we want to achieve?)
  • CSF – Critical Success Factors: Determinate factors to achieve the goal
  • KPI - Key Performance Indicators: Compare the CSF with standards, Quantities measurements
kpi for availability
KPI for Availability
  • MTTR (Mean Time to Repair): Average Down Time including Detect Time and Resolve Time.
  • MTBF (Mean Time Between Failures): Average Normal Operation Time
  • MTBSI (Mean Time Between System Incidents): Average time between two incidents
  • Availability Ratio: MTBF/MTBSI*100%
not too little not too much
Not too little, not too much
  • Measurement has costs
    • Tools
    • Time
    • Report
    • Analysis
  • Too many measurements only ends up with No measurement
  • Only measure the KEY performance indicators
itil philosophy five cost
