� Introducing Assisted optimisation

� Requirements for tooling

� Benefits

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

5

TELCOFANTELCOFANTELCOFANTELCOFAN

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

6

TELCOFANTELCOFANTELCOFANTELCOFAN

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

Analysing optimisation processesResults

� Several isolated systems processing the same data for similar or other purposes

� Each with their own GUI

� No correlation of data

� No prioritisation of network problems

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
