Cochrane Collaboration - Register of Studies Consultation

  1. 1. Cochrane Collaboration Register of Studies Consultation Steve Greenaway & Myles Gorton
  2. 2. Register of Studies Consultation • Objectives of the consultation – Clarify & prioritise the business & technical requirements for a new Cochrane Register of Studies Database System – Produce a Request for Proposal Document – Produce a Scoring Guide for responses to the RFP from potential solution providers
  3. 3. Register of Studies Consultation • Our approach – Document review of existing requirements (and RFP) in order to categorise into functional & non-functional – Production of the Requirements Catalogue – Production of High Level Architecture Diagrams – Prioritisation of all requirements via selected interview process using MoSCoW rules – Requirements priorities collated & aggregated • Here today to present the findings
  4. 4. High Level Architecture Diagrams

  10. 10. Requirements Prioritisation Results
  11. 11. Overall Prioritisation Overall Prioritisation • Using the MoSCoW rules 0% 6% – Must Have – the requirement is essential for the solution to work 11% – Should Have – the requirement is very important for the delivery of an efficient or cost effective solution – Could Have – the requirement is a “nice to have” and may enhance the solution, Must Have but it is not essential for functionality or Should Have efficiency. The requirement could be Could Have delivered later as an enhancement of Will Not Have the solution – Will Not Have – the requirement is of little or no benefit to the solution 83%
  12. 12. Web Application & Search Functionality Web Application & Search Functionality 2% • Requirements related to 9% the web application for the Cochrane Register of Studies, its functionality, 18% Must Have look and feel, accessibility Should Have Could Have and search functionality W ill Not Have 71%
  13. 13. Data Migration & Import Validation Data M igration & Import Validation 3% • Requirements related to 4% the importing of data from the Specialised Registers, 20% in particular relating to data migration and data Must Have validation processes Should Have Could Have Will Not Have 73%
  14. 14. Database Design & Reports Database Design & Repo rts 2% • Requirements related to the structure of database 20% tables, data types and data entity relationships. • Also requirements related Must Have to database reporting Should Have Could Have W ill Not Have 52% 26%
  15. 15. Interfaces & Integration Interfaces & Integration • Requirements related to 0% interoperability with existing 17% systems within and external to the Cochrane Collaboration 8% Must Have Should Have Could Have Will Not Have 75%
  16. 16. Workflow & Process Automation Workflow & Process Automation • Requirements related to 9% human-to-system workflow and system-to-system process automation. 16% • This area is related to Must Have Should Have interfaces and integration 46% Could Have Will Not Have 29%
  17. 17. Non-Functional Non-Functional • Non-business function 3% 1% requirements such as: – Accessibility 28% – Availability Must Have – Scalability Should Have Could Have – Performance Will Not Have – Resilience – Security 68%
  18. 18. Next Steps
  19. 19. Request for Proposal • Finalise Requirements Catalogue and High-Level Architecture diagrams for inclusion as Appendices in Request for Proposal – Produce the RFP – Produce the Scoring Guide – Publish the RFP • Obtain responses, score & rank suppliers • However…
  20. 20. Are There Other Options? • Based upon our understanding of the requirements, our findings so far and our experience – Many requirements = complex RFP = complex system – The solution has the feel of a “Rolls Royce” – Would a “Ford” or “Mini” suffice? – Is this the best use of the funding available? • Back to basics – what is the problem that we are trying to fix?
  21. 21. What are the problems? • Look of the data • Data duplication • Reference vs. Study based • Complete rebuild of CENTRAL with each publication • Searching • Workflow • Benefits of a centralised solution
