Chapter 1 Introduction

The skill of charting and consequently reading the KPI trend is one of the most basic things that I had to learn on the job as a Telco Engineer. I am using the skill to evaluate cell performance over a definite observation period (i.e. days, weeks, months, years etc.). Since it is a most basic skill, creating a guideline to do it nowadays is never a matter of serious consideration if not a downright laughable joke.

But, just like me, if you’ve become super-dependent on this 2-step procedure - first (1) create the chart out of a pivot table, second (2) slice-filter-look at the line chart, then it could be argued that you won’t be able to know the kpi trend pag di mo kita yung chart.
