Making it Happen – Making it Happen – PDQ Methodology (Agile)PDQ Methodology (Agile)

1. Daily Scrum meetings with mind mapping tools

2. Agility seeking i.e. maximum flexibility, least constraints in process, infrastructure, staffing, solutions, development

3. Top-Down Planning – Plan phases & milestones first, then progressive elaboration and rolling wave

4. Rapid, empowered decision-making with limited info

5. Time Boxing: Fixed time constraint for all tasks

6. Concurrent Engineering: Overlapping activities & early hands on

7. Dynamic Learning: Rapid, systematic info gathering

8. Kill Switch: Kill tasks or reduce scope where returns are diminishing

Hurdles - OracleHurdles - Oracle

Oracle database licensing– Problem: Oracle does not recognize soft partitioning– Solution: License one full blade– Problem: Oracle charges for temporary database licenses– Solution: Purchase temporary licenses

Oracle stance on supporting VMWare– Problem: Does not expressly support non-Oracle virtualization– Solution: Don’t worry, using VMWare won’t void your Oracle

support contract. Oracle just doesn’t support 3rd party infrastructure.

Hurdles – Internal PerceptionHurdles – Internal Perception

Internal mis-perceptions

• Myth: Linux is inferior to UNIX

• Fact: Linux is Oracle’s go-forward JD Edwards platform

• Myth: VMWare adds too much overhead for ERP

• Fact: VSphere in particular delivers stellar performance

• Myth: Minicomputers are superior to Intel blades

• Fact: For all MLCC’s mission-critical applications (ERP, network, point-of-sale, records management, data warehouse) blades/VMWare are better, faster, much cheaper, and far more flexible.

Hurdles – Cont’d.Hurdles – Cont’d.

Internal mis-perceptions

• Myth: No one else is doing ERP on VMWare

• Fact: We found many companies that have successfully virtualized ERP.

• Myth: If any major problems arise, VMWare must be the cause.

• Fact: During our 17 month project, virtualization was often suspected but cause was always elsewhere e.g. database or memory tuning.

Free TipsFree Tips

Relationship management (politics):• Enlist an executive champion that will help calm powerful

naysayers.

• Helpful due diligence -- networking (LinkedIn), consultant assessments, case studies, and reference calls.

• Be prepared to re-address virtualization phobia with each new problem.

Team building: • Use agile project management techniques.

• Get teams to research and try virtualization as early as possible.

Free Tips Cont’dFree Tips Cont’d

Technical:

• More assessment whether to use raw partitions for database or VMDK.

• Performance problems are hard so stress-test early.

Standards:

• Standardize on virtualization and communicate those standards.

• Make virtualization a mandatory requirement on application RFPs.

AccomplishmentsAccomplishments

Smoothest ERP go-live we’ve ever had. On time, on budget, high quality. Earned praise from Executive and Board.

Moving off minicomputers saved about $500K per year in maintenance and lease costs.

Achieved vastly greater flexibility e.g. rolling upgrades, mirroring to DR site, and server/resource provisioning.

Reduced server room power and cooling requirements – eliminated 5 racks of minicomputers at HO and DR.

Given the flexibility of our virtualized environment, the next ERP upgrade will be a piece of cake.
