BI Project• Background Information In business since 1997, SetFocus is the global leader in selecting, training, placing, and supporting

Microsoft professionals worldwide. Through strategic relationships, SetFocus develops programs that directly source skilled professionals to meet the immediate hiring needs of its partners.

• Business Problem After each course week, an administrator uses a windows application to generate evaluations that are

sent to the students via email. Students fill out the evaluations and submit them using a web based application. The data generated by the evaluations is tracked and used to tune and improve performance in an array of areas. The main categories that are evaluated are lecture week, project week, room rental, and career development. Some of the areas that are evaluated within the main categories are instructor performance, course materials, curriculum, infrastructure, and support. A grading scale is used and a cumulative grade is given for each specific area per class session.

The primary categories currently used are:•Lecture Week•Lab Week•Final Evaluation

And the subcategories include:•Trainer•Support•Materials•Curriculum•Infrastructure/grid•Career development

The end user will be able to select a grade for each individual question on the evaluation. The scale is based on the numbers 1 though 10 with 1 being the lowest grade and 10 being the highest. N/A = 11Currently, the training and support department uses a set of reports to measure and manage performance. As part of the performance improvement initiative, the training and support department would like to build various reports and dashboards.

Terminology

Reporting period / quarterRefers to calendar quarter. All courses with evaluation date sent falling within the calendar quarter will be reported.

DatabasesTwo primary databases that will be used for the source data are:NewSFCoursesSurveyEvaluation

Source Database: SurveyEvaluation

Source Database: NewSFCourses

Identify Facts/Measures

Based on the report mockups the primary facts from the source database were identified as:

ScoreEvaluations Sent/Evaluations ReceivedComments

Identify Dimensions/Hierarchies

We first identified the major dimension hierarchy:

TrackTimeOfDaySessionCourseQuestion

Identify Dimensions/Hierarchies

Date Dimension: We developed a Date Dimension to join to the Session Dates. We only wanted the dates down to the Day level.

Stored Proc: Populate DimDate

Data Warehouse – Data Diagram

Set Focus Evaluation Datawarehouse ETL Utilizing SSIS

Master Package

Dim Session Course Package

- This dimension will be the most active dimension.- This dimension will consolidate the SF Courses database- Several lookups to the data dimension are referenced and the course end date is the primary date reference in the database.

Fact Evaluation

The fact evaluation table will be used as a counter for completed vs. uncompleted evaluations.A validation was done on SessionID which creates an error data file.

Summary

• Perform bulk of calcs/member in Cube– Success

• Consolidated DW = Simpler Cube– Worked well

• Phase II changes will depend on DW and Reporting needs– Phase I stable and usable as is

Reports

• Summary Drill Down Scores by Track, Time of Day, Session.

• Primary dashboard Latest week and quarter-to-date scores by track & sub-category with KPIs.

• Trainer vs. Overall Scores for a specific instructor/trainer for the current quarter compared to the overall Scores for all instructors in the same period.

• Trainer Scores for the past iterations (up to 10) for that course for that trainer .

• Trainer Date Range Evaluation scores within a date range .

• Trainer Detail Detailed report of evaluation scores on last day/night class taught.

* User should be able to access Trainer Detail report from Trainer and Trainer Date Range reports.

Summary Drill Down Report

• Developed using SSRS.• Shows [Average Score] by

track, time of day (day and evening) and session.

• Can drill down on Track. • Can collapse on Time of Day to

Primary Dashboard

• Developed in SSRS.• Shows [Average Score] “Value”

for the latest week and quarter-to-date “QTD Value” for Track & Sub-Category “Indicator”.

• The goal is 9.2. • >= 9.2 is green

>= 9 and < 9.2 is yellow< 9 is red.

• % Responded reflects percentage of evaluations completed for the latest week and quarter-to-date.

• >= 75% is green >= 50% and < 75% is yellow < 50% is red

Trainer vs. Overall

Trainer vs. Overall

• Developed using PPS.• Tracks the [Average Score] for

a specific instructor/trainer over the current quarter compared to the overall [Average Score] for all instructors over the same period.

• Instructor is a drop-down single-select parameter.

• Current quarter is defined as the most recent quarter with data.
