Analysing optimisation processesObjective & Methodology
� Objective: “Investigate current ongoing projects how money could be saved while maintaining or improving on the quality of the existing processes”
� Shadowing ‘day to day’ tasks
� Different engineering levels and regions� Use of industry experts
� Check existing processes, targets and challenges� Check Process Interfaces
� Note all tools used
� (‘Real’) Timeline of activities� Identification of potential bottlenecks

Analysing optimisation processesResults
� Lots of manual operations� visual correlation of alarms, triggers, bad KPI’s
� check Top 10-30 for XX KPI’s without prioritisation
� manual report creation
� protocol or call trace export and scrolling
� loading drive test data for replay one by one
� typing results from one tool to the other
� …
� Lots of network data collected but mainly unused
� Not enough time/resources to solve all the issues

Analysing optimisation processesResults
� Management unable to get insight and control
� Processes not known
� No uniform approach or lack of methodology
� Commercial tools not properly used to the full capabilities� bad implementation, not known, not customised, bad performance,
…
� Lots of isolated internal build sheets, Access queries and desktop tools
� Number of tools found typical 50-100 in Radio teams only

Assisted optimisationDefinition
“Efficient optimisation using future-proof automated
solutions that provide relevant prioritised issues
including all required diagnostic information for quick
resolution”
≠ SON: Self-Optimising Networks

Assisted optimisationWhy now?
� Revenues growth is slowing or non-existent
� Costs <> Workload� Budget cuts
� Headcount cuts
� Workload doesn‘t just go away
� Technology is increasingly complex� 2G+3G+4G+…
� Outsourcing� Vendor management
� First automate then think about outsourcing

Assisted OptimisationRequirements for Tooling
� Correlate data to automate issue finding� Input data: any open data source
� Correlation allows prioritisation and better diagnostics� Most important issues are addressed first
� Filter to only relevant issues� Reduced overhead of data
� Extreme data processing performance� Multi-processing, Cloud computing
� Distribute network issues as tickets� allows workflow management
� Reporting on ticket status, type of issues, per Engineer….� One combined data warehouse bringing all data together
� Cross-platform and ‘open’
� Easy to use GUI� Future proof and easy adaptable ->Customisable

How to quantify possible benefits
� Quantitative benefits:
� Labour
� Time spend optimisation resources on daily process-> Productivity
� Cost of external resources: contractors, drive test, managed services,…
� Alternative for outsourcing
� Maintenance of tools
� Less tools less opex
� Including internal tools !
� Process Cycle time improvements
� Faster time to market or launch
� Better MTTR
� Calculate savings and include in ROI
