!Mr. White has ﬁfteen years of experience designing and managingthe deployment of systems monitoring and Event Managementsoftware. Prior to joining IBM, Mr. White held various positionsincluding the leader of the Monitoring and Event Managementorganization of a Fortune 100 company and developing solutions asa consultant for a wide variety of organizations, including theMexican Secretaría de Hacienda y Crédito Público, Telmex, Wal-Mart of Mexico, JP Morgan Chase, Nationwide Insurance and theUS Navy Facilities and Engineering Command.!!Andrew White!Cloud and Smarter Infrastructure Solution Specialist!IBM Corporation!

I have a lot of experience leading !Systems and Event Management teams !My name is Andrew White!
Cloud Operations!I am here today to share some of what I have learned about!
More importantly, I am here today to talk abouthow the cloud affects…!
QUESTION:!What value does your IT organizationcreate for your business?!
If you can’t answer this question, howcan you be sure you are doing theright things and doing them well…!
HINT: “We provide infrastructure or applications thebusiness uses” is not a value statement!
Follow Us: #ITSMSummit!We are all here for one reason…!
How does IT preserve the value it creates?!• 100% Uptime*!• Scalability*!• Performance*!• Agility*!• Good UX*!!*To the best of our ability!
Follow Us: #ITSMSummit!CURRENT MARKET CONDITIONS!§ The velocity of change and the volume of data is increasing!§ Virtualization introduces complexity and increasedconsumption of resources!§ Shared services are forced to oversubscribe ﬁnite resources!§ Expertise is limited to functional silos and there is nounderstanding of how the system functions end-to-end!§ Supporting a cloud requires the ability to manage a large-scale dynamic infrastructure!§ Agile development and Continuous Delivery are in conﬂictwith ITIL processes!
We need to recognize when wehave problems to solve!
Follow Us: #ITSMSummit!To solve problems quickly, we look for solu5ons that we can use to deﬁne best prac5ces and develop processes to insert a measure of control. THE TRADITIONAL APPROACH!
Follow Us: #ITSMSummit!§ Solutions are driven by accepted conventions!§ Best practices are coveted and are usually adoptedwithout understanding how and why they were developed!§ There must always be a right answer!§ No logical analysis is required!§ People are frequently seen as the “root cause”!§ The outcomes are enforced using “re-dos” and punitiveactions (or the looming threat of these things)!THE PROBLEM WITH THIS APPROACH!
Follow Us: #ITSMSummit!§ We receive feedback from our business partners that system performance andavailability have been unacceptable for many of our critical businessapplications!§ Our productivity is impacted and we fail to meat delivery timelines!§ IT is not able to measure its impact on the business or the end user experience!§ There is a lack of clear communication during a problem!§ People are “hoarding” data and reports!§ IT lacks the information needed to prioritize performance issues andopportunities based on business need!§ We take a really long time to ﬁgure out what is wrong!§ The same old problems keep coming back!§ We never really get to the “true root cause”!HOW DO WE KNOW WE NEED TO CHANGE!
Follow Us: #ITSMSummit!Our typical approach towards serviceimprovement is a bit like attempting toput the toothpaste back in the tube!! “Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them.” -‐ Laurence J. Peter CONTROL IS AN ILLUSION!
Organizations don’t fail because they take the wrongpath, they fail because they can’t imagine a betterpath than the one they are on.!! ! ! ! ! ! ! ! ! ! !-- Marty Neumeier!
Is it the infrastructure or the application?!The perennial problem….!
Follow Us: #ITSMSummit!CLOUD PAIN POINTS!§ It takes too long to diagnose problems in theapplication and infrastructure!§ Existing management tools are outdated and don’twork at scale!§ Critical information is missed causing outages andpoor user experiences!§ Most problems are managed reactively!Does any of this sound familiar?!
Follow Us: #ITSMSummit!REQUIREMENTS FOR UNITY OF EFFORT!1. Commandand Control!2. SharedExperience!3. SituationalAwareness!• Command and control (No Leadership)!• The team lacks a clear direction!• Lots of activity, lack of progress!• Shared Experience (Poor Relationships)!• Us vs. Them mentality!• Unhealthy competition!• Situational Awareness (Poor Communication)!• Focused on cooperation, not collaboration!• Blame culture!• Infrequent or non-existent communication!Symptoms of Missing Elements!
Follow Us: #ITSMSummit!TWO TYPES OF DECISION MAKING!§ Programmed Decisions!§ Routine!§ Repetitive!§ Well-Structured!§ Predetermined DecisionRules!§ Non-Programmed Decisions!§ Unique!§ Presence of Risk!§ Presence of Uncertainty!§ Black Swans!

Four Sources of Bad Decisions:!!1. Failure to frame the problem correctly!2. Poor use of evidence!3. Faulty decision making process!4. No feedback for improvement!

Follow Us: #ITSMSummit!NORMATIVE DECISION MAKING MODEL!§ Limited Information Collection!§ 7 +/- 2!§ Tendency to acquire manageable rather than optimal amountsof information!§ Difﬁculty identifying all possible options!§ Judgmental Heuristics!§ Judgmental heuristics - rules of thumb or shortcuts that peopleuse to reduce information processing demands!§ Availability heuristic - tendency to base decisions oninformation readily available in memory!§ Representativeness heuristic - tendency to assess thelikelihood of an event occurring based on impressions aboutsimilar occurrences!§ Satisﬁcing!§ Choosing a solution that meets a minimum standard ofacceptance!
1. Adapted from Endsley, M.R. (1995b). Toward a theory of situation awareness in dynamic systems.Human Factors 37(1), 32–64.!!Our systems are capable of producing a hugeamount of data, both on the status of their owncomponents and on the status of theenvironment. The problem with today’s systemsis not a lack of information, but ﬁnding what isneeded when it is needed.!

We have experienced that many ofour clients use this as an opportunity to re-evaluate the way they operate their environmentsand the tools they leverage to deliver a quality service.!We have identiﬁed three key goals driving the adoption of the cloud:!
Follow Us: #ITSMSummit!WHAT THIS MEANS TO US…!There are a few inescapable facts we face:!1. We needs reliable systems to store the promises itmakes to its customers !2. Our systems mirror the complexity of thebusinesses they support!3. Our environments must be massive to scale tohandle the workload!4. There is too much activity for a single person to betotally situationally aware!5. If the users can’t use it, it doesn’t work!
