Opportunities for Standardization
Need standardization for every interaction between members
Standardizing VDW Development Processes
Standardizing Multi-site Research Studies Processes
Focus on Two Aspects
SAS Program names Sequential number Date Brief description of program Version Number
Example: 1_20110315_M2Util_v1 2_20110520_M2Util_v2 3_20110622_QAUtil_v1
SAS Output Datasets Example: 1_20110315_M2Util_v1.sas7bdat
SAS Log/SAS Output Example: 1_20110315_M2Util_v1.log 2_20110315_M2Util_v1.list
Guidelines Word document name Example: 1_20110315_M2Util_v1.doc
SAS Library names Example:Outlib/Out1/Output1/Send/SentWorkLib/In1/Input1 etc
Possible Areas for Standardization in VDW Development
Meeting Minutes TemplateAgenda TemplateHeader information for any document posted on
CRN Portal
Standardization Areas cont.
‘Header’ & ‘Footer’ information for Documents on CRN Portal
Title of the document Created by person’s name and email addressCreation dateRevision numberRevised by person’s nameRevision dateReason for revisionFinal documents location on the portal (Footer)Revision number (Footer)Revision date (Footer)Page number out of total page numbers (Footer)

Who Will Benefit Most?
New SAS Programmers/VDW Developers
Lead Site-SAS Programmers working on multi-
site Studies
HMORN Workgroup Members
Site Data Managers (SDMs)
Next StepsForm a Workgroup : ‘VDW Standards’
All standardized templates should be available on CRN
portal at:
Home ->Data Resources ->VDW ->User Guidelines and Tools
All new documents to be uploaded should go through a
standards review
All existing documents on CRN Portal should be revised as
per new standards
All Lead Site programmers should follow same standard
guidelines before sending out programs
Advantages
Keep track of revision numbers and order of
programs to run
Easier for new programmers to join on-going studies
Easy start for Lead site programmers (download
template and start working on content)
Efficient and effective way to document large
studies
Clear/consistent document standards across all
HMORN sites
