  1. EIDE System Requirements and Specification Documents WECC DEWG EIDE Training

  2. Overview • What you will need to specify • Identifying deliverables • Specification boilerplate

  3. What you will need to specify • Network infrastructure • Security • Back office interfaces • Data mapping • Triggers • Error conditions • Redundancy

  4. Network infrastructure • How can you use your existing network infrastructure to meet your security and functionality requirements? • Possibilities include: • Smart listener with code and access to back office through secure sockets or ports • Dumb listener with ability only to write documents • Somewhere in between

  5. Security requirements • Any design you create must meet your security requirements and should be reviewed by the 1300 compliance monitor. • Firewall policy • DMZ policy • Authentication policy

  6. Back office interfaces • Which systems will you be getting data from and sending data to? • How? Database, file, three tier? • Can changes to the back office systems be isolated from the gateway? • What methods will be implemented? • How will you ensure reliability?

  7. Data Mapping • How will you flexibly map data between your system and others? • EIDE protocol is flexible and allows various methods. • Database structure and programming logic can allow any combination. • Hierarchical approach can be used.

  8. Triggers • Timed transfers? • Who sets these up and how? • Manual transfers? • What does the user interface look like? • Will you do gets?

  9. Error conditions • What happens when you get an invalid inbound document? • What happens when your database is temporarily down? • What happens when you can’t find a path for a file write? • What happens when the receiver system is down? • How are timeouts and bad responses handled? • Do you need acknowledgement?

  10. Redundancy • Dual internet connections through different vendors • No single point of failure • Hot standby configurations • Parallel configurations • Failover between database sessions

  11. Identify Deliverables • Based on what tasks are to be performed • Assign responsibilities • Specification documents can be created for each module with interfaces specified in each • Deliverables may include: System Requirements Document, System Design Document, Database Design, Detailed Design, Technical Documentation, User Documentation, Data Dictionary or Glossary, RFP, Statement of Work

  12. Specification boilerplate • Introduction including project scope, specification overview, and description of existing systems • Functional Requirements with subsections for each functional area • User interface requirements • Hardware and software requirements • Sizing, expansion, performance, upgrade, testing • Documentation and Training • Maintenance

  13. Functional Requirements • Should specify “what” rather than “how” with exceptions where required • Should allow for creative implementations • Identify which methods will be required • Identify any specific implementation requirements for back office interfaces • How 23 and 25 hour day is handled • How data is mapped

  14. EIDE requirement examples • Data sets containing a combination of EMS and Scheduling information can be configured to trigger each hour at HH:MM, each day at XX:MM, each week at XX:MM • Data from EMS and scheduling system can be sent using either PutSchedule or PutMeter • Messages received will be displayed at the _______ console in a popup box

  15. EIDE Specification • Compliance with schema and communications protocol document • Ability to integrate schema modifications • Functional requirements include validation of received documents based on your own business rules, back end system interfaces • User interface requirements include both administrative and user.

  16. EIDE Spec • Functional requirements should also specify data translation requirements, whether gets will be used, etc. • Should also include timing requirements if there are any • Be sure to include 23 and 25 hour day handling, data compression, error conditions, etc.

  17. RFP and SOW boiler plate • Needs to include: • Terms and conditions • Responsibilities, deliverables, schedule, disclosure, termination, performance, project rights, agreement on definition and handling of work outside scope, invoicing and payments, software license/ownership,etc. • Project organization and procedures • Any company specific requirements

  18. Tool choices • There are many good tools available for describing the functional requirements • These include DFD, UML, relationship charts for database…
