Introduction - How to Manage IT ?

• Too many acronyms - too little time !

• These days, IT managers are faced with a whole raft of different methodologies and approaches.

• Are they all relevant? • What are the strengths and weaknesses of

– ITIL

– CMMi

– MOPS

– six-Sigma

– LEAN

– ….. ?

• Are they mutually exclusive?

Focus on PROCESSES rather than SKILLS

Functional OrganizationFunctional Organization

Process ApproachProcess Approach

Using a Process Approach, we no longer think in terms of individual technical teams “doing their own thing”.

Rather we think in terms of the overall goal which should be directed to the main goals of the organization.

What is ITIL?

• ITIL = “Information Technology Infrastructure Library”• A Library of Processes books outlining “good practice” for

managing IT Infrastructure.• A set of ready-made “how to” references.

• ITIL IS A NON-PRESCRIPTIVE REFERENCE

• ITIL® is a Registered Trade Mark, and a Registered Community Trade Mark of the Office of Government Commerce, and is Registered in the U.S. Patent and Trademark Office

• ITIL revision 3 released in June 2007, although many people still prefer version 2 at this time.

• A British Standard (BS 15000) certification (BS 25000 to come).• Linked to ISO 9000 Quality Certification, ISO 20000

IT’s all a question of MATURITY

• Level 1 – Initial– Processes are usually ad hoc. Success depends on the

competence and heroics of the people in the organization.

• Level 2 - Repeatable [Managed]– Successes are repeatable. Existing practices are retained during

times of stress.

• Level 3 - Defined– The organization’s set of standard processes, which are the basis

for level 3, are established and improved over time.

• Level 4 - Quantitatively Managed– Using precise measurements, management can effectively control

the effort, and can identify ways to adjust and adapt

• Level 5 - Optimizing– Continually improving process performance through both

incremental and innovative technological improvements.

Some Process Areas which need to be Mature...

• “Engineering”– REQM - Requirements Management (2)

– RD - Requirements Development (3)

– TS - Technical Solution (3)

– PI - Product Integration (3)

– VER - Verification (3)

– VAL - Validation (3)

• “Support”– CM - Configuration Management (2)

– PPQA - Process and Product Quality Assurance (2)

– MA - Measurement and Analysis (2)

– DAR - Decision Analysis and Resolution (3)

– CAR - Causal Analysis and Resolution (4)

Engineering + Support + Project Management + Process Management

And More Process Areas...

• Project Management– PP - Project Planning (2)

– PMC - Project Monitoring and Control (2)

– SAM - Supplier Agreement Management (2)

– IPM - Integrated Project Management +IPPD (3)

– RSKM - Risk Management (3)

– QPM - Quantitative Project Management (4)

• Process Management– OPD - Organizational Process Definition +IPPD (3)

– OPF - Organizational Process Focus (3)

– OT - Organizational Training (3)

– OID - Organizational Innovation and Deployment (4)

– OPP - Organizational Process Performance (4)

Engineering + Support + Project Management + Process Management

How CMMi Concepts can help

• The Concept of “Maturity” is a valuable way of assessing your own organisation.– (Even if you do not want to use the whole CMMi Model).

• CMMi emphasis comes originally from the Development Project Life-Cycle, although it references the Production side.

• “roll your own” Maturity.

COBIT

Control OBjectives for Information and Related Technology

• Audit Based way of assessing IT Projects specifically.

• Emphasis on Governance, and defining IT Controls.

• Often used in SOX assessments.

• Also has it’s own maturity model...

• Basic Framework for managing IT:– Plan and Organise

– Acquire and Implement

– Delivery and Support

– Monitor and Evaluate

COBIT Structure

• Plan and Organization– PO1 Define a Strategic IT Plan and direction – PO2 Define the Information Architecture – PO3 Determine Technological Direction – PO4 Define the IT Processes, Organization and Relationships – PO5 Manage the IT Investment – PO6 Communicate Management Aims and Direction – PO7 Manage IT Human Resources, PO8 Manage Quality – PO9 Assess and Manage IT Risks , PO10 Manage Projects

• Acquire and Implement– AI1 Identify Application Software – AI3 Acquire and Automated Solutions – AI2 Acquire and Maintain , A13 Maintain Technology Infrastructure – AI4 Enable Operation and Use , AI5 Procure IT Resources – AI6 Manage Changes , AI7 Install and Accredit Solutions &

Changes

COBIT Structure (cont)

• Delivery and Support– DS1 Define and Manage Service Levels , DS2 Manage Third-party

Services

– DS3 Manage Performance and Capacity, DS4 Ensure Continuous Service , DS5 Ensure Systems Security

– DS6 Identify and Allocate Costs

– DS7 Educate and Train Users, DS8 Manage Service Desk and Incidents , DS9 Manage the Configuration , DS10 Manage Problems , DS11 Manage Data , DS12 Manage the Physical Environment , DS13 Manage Operations

• Monitor and Evaluate– ME1 Monitor and Evaluate IT Processes

– ME2 Monitor and Evaluate Internal Control

– ME3 Ensure Regulatory Compliance

– ME4 Provide IT Governance

COBIT and ITIL.... ?

• ITIL V3 references COBIT, and it can be argued that these are closely aligned.

• The emphasis in ITIL is on Continuous Improvement of Service Operations, whereas COBIT is primarily concerned with Governance (mainly of Projects).

The Six-Sigma Process Improvement Cycle

• Select Priorities• Learn about the Process• Investigate Sources of Variation• Test Theories• Study Results• Implement• Standardise• Review

DEFINE – MEASURE – ANALYSE – IMPROVE - CONTROL

Using Six-Sigma

• Although Six-Sigma originated in the field of Engineering, it is a practical Project Approach which can be used for improving IT Processes.

• Some aspects of Six-Sigma are also referenced in ITIL, including:– PDSA cycle (“PDCA”)

– Root Cause Analysis

LEAN

Value: “Something a process contributes that makes a product or service valuable in the eyes of the customer and which they are

prepared to pay for”

Value: “Something a process contributes that makes a product or service valuable in the eyes of the customer and which they are

prepared to pay for”

Identifying “Waste” in Processes

Value Enabling?

Seven Wastes

• Overproduction:– Producing ahead of what's actually needed by the next process

• Waiting:– Operators standing idle, equipment fails, needed parts fail to arrive.

• Conveyance:– Moving parts and products unnecessarily.

• Processing:– Performing unnecessary or incorrect processing.

• Inventory: – Having more than the minimum stocks necessary for a pull system.

• Motion:– Movements, such as looking for parts, tools, documents, etc.

• Correction: – Inspection, rework, and scrap.

LEAN Thinking

• LEAN is often used alongside Six Sigma.• Focuses on the causes of processes being inefficient.

• Although it originate in the engineering disciplines, it can be used effectively to reduce the “cycle time” of IT processes.

MOPS

After the Project goes Live….

… the real problems begin…

MOPS™ : Managing IT ProductionMOPS™ : Managing IT Production

IT Management = Management AND IT

• MOPS is an attempt to integrate a number of different methodologies and approaches and apply them to the technical challenges of managing IT Production.

• METRICS– Publish what IT Production does to get business buy-in– Measure what you do in order to manage the teams

• OPERATIONAL TOOLS– Chose software to improve your ability to manage the infrastructure– “Referential” approach to standardise reporting across teams

• PROCESSES AND PROCEDURES– Use ITIL pragmatically as a start, Six-Sigma / LEAN to improve,

and interface with Development Project processes.

• STANDARDS– Chose Technologies based on “Production-ready” criteria to

optimise the costs of Production Support.
