L13 Completed Ahead of Schedule and On Budget
Project initiated in Oct 2008 Reported progress in April 2009 to Reliability TCC Project extended 12 months with additional
$75,000 to develop a prototype – commenced Sept 2009
Delivered preliminary draft final report in Nov 2009
Completed prototype early Jan 2010 Draft final report submitted March 2010 – six
months ahead of plan

L13 Yields Meaningful Outcomes Suited for Implementation Established conclusively that the recommended
approach based upon a digital repository management system with a flexible metadata management scheme, combined with cloud storage, is highly feasible
We were able to assemble a prototype system exclusively from no-cost, open source software that approximates the expected user experience of a real-world system
Provides a broadly applicable reference model for how the intellectual capital embodied in transportation research programs can be preserved and made accessible

L13 – A Project with Broad Implications
Study to determine feasibility of building a long-lived archive to preserve Reliability Focus area project data ► “in the range of 20 to 50 years”► “to allow others to validate the research results”► to make the data “available for researchers in the future
to refine and build on the research results”
Has a material impact on how all Reliability project data and findings can become useful “products”
SHRP 1 experience illustrates the importance of preservation planning

Users Servedby the Archival System
Researchers and AnalystsInterested in verifying research results and building new research programs
Need to find raw data and research methodologies
Non-Transportation ProfessionalsInterested in end products on operational strategies
Need to quickly find project conclusions, results and strategies
Transportation Technical StaffInterested in applying end products to daily operationsNeed to quickly find end products based on roles and responsibilities
Transportation LeadersInterested in small, critical data set for business decisionsNeed to quickly find project conclusions

Prototype
In a relatively short time the Weris team assembled a prototype system exclusively from no-cost, open source software that approximates the expected user experience of a real-world system
We were able to deploy the system on a completely virtualized environment using readily available commercial cloud computing services
We demonstrated that this approach minimizes up-front cost and risk

Findings and Conclusions
We believe that we have established that it is highly feasible for the SHRP 2 program to cost-effectively deploy a data archival system that meets all of the goals and objectives envisioned by its major stakeholders
We recommend that the SHRP 2 program proceed with the L13a Reliability archive project as planned, following the L13 approach
13
Critical Success Factor 1 for L13a and L16
Independent COTS Evaluation
COTS proposed for L13a should be evaluated independently
COTS evaluation will take time
Evaluation time must be built in to the procurement process
14
Critical Success Factor 2 for L13a and L16
Set Standards Early
Decisions on standards and practices are independent of any COTS to be implemented
Standards must be set well in advance of system implementation
15
Critical Success Factor 3 for L13a and L16
Knowledge Preservation
Institutional knowledge about a project deteriorates with time
Preparation for preserving intellectual content of research projects must start during early stages of the projects’ lifecycle
16
Critical Success Factor 4 for L13a and L16
Provide Education
Project contractors must be educated on the archiving preparation process
Archiving preparation needs to be actively managed
17
Critical Success Factor 5 for L13a and L16
Program Management
The critical program management role will encompass the systematic management of
- contractor engagement and education
- content preparation and submission
- software procurement
- system development and deployment
