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
