Net DAS AOS FLT EEE … • Construction Services • Support Services – Network Support Service – Application Maintenance Service – Database Maintenance Service – Infrastructure Maintenance Service • Management Services – Statistics and report – Communication and Training – Consulting

Behave like Service Providers • Align IT services to the customer and business needs. Behave like Service Providers • Align IT services to the customer and business needs. Find out what the customer needs and make those services available • Partner with the customer to create new ways of doing business. Create new competitive advantages. • Increase the quality of the existing services by organizing around services and working to make those service efficient

Realize the promise “We care about our Customer!” • Documenting, negotiating and agreeing Customer Realize the promise “We care about our Customer!” • Documenting, negotiating and agreeing Customer and business quality targets and responsibilities in Service Level Agreements (SLAs) • Regular assessment of Customer opinions in Customer Feedback and Customer Satisfaction Surveys • IT personnel regularly taking the ‘Customer journey’ and sampling the ‘Customer experience’ • IT personnel taking the Customer and Business perspective and always trying to keep Customer interactions as simple and enjoyable as possible

Expected Results • Alignment – Better match IT capability and costs to business needs Expected Results • Alignment – Better match IT capability and costs to business needs • Efficiency – Extend existing resources • Reliability – Ensure consistent performance • Agility – Response to business and technology-driven changes

ITIL Philosophy Two - Quality • Quality is the “degree to which a set ITIL Philosophy Two - Quality • Quality is the “degree to which a set of inherent characteristics fulfils requirements” as in ISO 9000 • Service Quality is “about ensuring customers get what they want” as in Managing Service Quality • Quality is a interactive term. It’s all about satisfying and exceeding Customer Expectations.

What does that mean? • High quality of the product cannot be achieved without What does that mean? • High quality of the product cannot be achieved without understanding what customer wants (requirements) • Quality cannot be measured without asking the customer’s opinions • High quality service cannot be delivered without thinking in customer’s perspective

How Customer Evaluate Service Quality? • Did the service satisfy my expectation? • Can How Customer Evaluate Service Quality? • Did the service satisfy my expectation? • Can I get the same service next time? • Is the service provided by a reasonable cost?

Continuously Improve Service Quality Where are we now? Current process & procedures Current challenges 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 How do we keep the momentum going

How to get there - Quality Improvement Model Deming Circle (PDCA) • Plan: Plan 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

ITIL Philosophy Three - Process “A process is a specific ordering of work activities 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 • Definability: It must have clearly defined input and output • 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 Oriented Management – Results can map to Activities – 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? • Service – Intangible: Customer 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? Give • Understand the whole picture • But, what does process mean to me? Give • Understand the whole picture • Know what to do in any circumstances • Clearly defined Roles/Responsibilities • Measurable performance • Save time and efforts Take • May change way we used to carry out our tasks • Take away some flexibilities

ITIL Philosophy Four - Measurement If you cannot measure it, you cannot manage it 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 What do we mean “Measure” here? • Check in PDCA • Evaluate if we are in the right direction? Goal Are we in the right direction? Start Point

Why “Best Effort” is not good enough? • “Best Effort”, “Some Progress”, “Improved Performance”… 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? • Goal (Where do we want to go? What are we 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

Example: Measure Availability Example: Measure Availability

KPI for Availability • MTTR (Mean Time to Repair): Average Down Time including Detect 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 • Measurement has costs – – Tools Time 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 Everything comes with a cost – Equipment Cost – ITIL Philosophy Five - Cost Everything comes with a cost – Equipment Cost – Software Cost – Organization Cost – Accommodation Cost – Transfer Cost – Cost Accounting

How Cost are related to us? • • Budget Salary/Bonus Reimbursement Training Cost Tools How Cost are related to us? • • Budget Salary/Bonus Reimbursement Training Cost Tools Hiring It’s everywhere in our working life! (Personal life too)

Cost Awareness – Thinking as the Management • Budget – Can we make the Cost Awareness – Thinking as the Management • Budget – Can we make the ends meet? • New Project – ROI (Return Of Investment) = Profit / Investiment • New Software/Hardware/Tool – TOS (Total Ownership Cost): Cost in its lifetime

Hidden costs • Management cost – Statistics and Report – Communication and Training • Hidden costs • Management cost – Statistics and Report – Communication and Training • Support cost – Installation/Upgrade – Incident Support – Performance Tuning

ITIL Philosophy Six - Proactive • Common feelings about work – I am too ITIL Philosophy Six - Proactive • Common feelings about work – I am too busy – Work is chasing me. I am stressed out – I don’t have time to do the meaningful things. – Those issues are so bugging. They kept coming back!

Breaking things down • Reactive activities – Handle customer complains – Handle production outage Breaking things down • Reactive activities – Handle customer complains – Handle production outage – Last minute purchase – Deal with disasters • Preventative activities – Create contingency plan – Setup knowledge database – Setup Production Monitors – Capacity Planning – Create Disaster Recovery Plan

First thing first • The more you work on Preventative Activities, the less you First thing first • The more you work on Preventative Activities, the less you need to work on Reactive Activities • Take the control back! – Preventative activities are under your control while Reactive Activities control you.

Some Proactive Activities Suggested by ITIL • Problem Management: Study the trend of the Some Proactive Activities Suggested by ITIL • Problem Management: Study the trend of the incidents. Dig out and fix the fundamental problem. • Configuration Management: Keep track of important things and their relationships • Capacity Management: Project the workload. Plan the capacity ahead of time • And a lot more….
