1

Load Research – Process Map

MainFrame SAS

Obtain Population File

(“Pop file”)

Identify decision parameters, such as

Sample size, error ratio, precision level,

etc. in MBSS Parameter Sheet File

MBSS/PC SAS

Populate MBSS tables

with Population Data

Load Research – Process Map

MainFrame SAS

Is the precision level

within ±10%?

Draw Stratified Random Sample

from Population File based on

given decision criteria

Analyze a combination of parameters (e.g. precision level, sample size, error ratio, etc.) for preliminary sample

Yes

MBSS/PC SAS

No

Load Research – Process Map

Run the list of accounts/service

numbers against CBMS mirror to obtain additional customer & meter data

MainFrame SAS

MBSS/PC SAS

Metering to install all IDRs for the

sample list and report back after the installation of IDRs in the list is complete

Send out the sample list with additional variables to metering

MBSS/PC SAS

Provide alternate sample

IDRs on case-by-case basis

Yes

Any IDRs not installed

due to constraints?

Metering & Field

Operations

Inventory newly installed IDRs into RDS & IDRP databases

No

New sample complete

4

Load Research – Process Map

Are all samples installed

and providing data?

MainFrame SAS

Periodically audit the IDRP tables against Primary & Alternate sample Lists for completeness (i.e. all newly installed meters have been read at least once)

Collection of half-hourly interval data and storing on IDRP

Send out the removal list of IDRs that were part of the old sample
