  1. DØ OnlineTechnical Design Report • What is it? • It needs to be a fairly comprehensive document detailing the plans, costs, schedules, and resource (manpower) needs for the Online system. It is a component requirement of the DOE Lehman review of the entire upgrade project. • It should also be the basis for our documentation of the as built system. • In what form? • The document presented to the Lehman reviewers needs to be printed - hence it must fit into a serial format • Our working document might be better maintained as a number of (hyperlinked) distinct components • Suggest we produce chapters or sections according to the project components

  2. DØ Online TDR • What should it contain? • Requirements • As much design and implentation detail as… • is known • is possible • is correct but at a maintainable level • Costs • Only needed for the hardware section • Personnel costs not considered • Schedule • Typically only a handful of tasks (aka WBS lines) per section • Only a few milestones per section • Should feed into the (revised) master project schedule • May need to be periodically updated • Be careful to consider interdependencies with other sections!

  3. DØ Online TDR • When is it needed? • Next Lehman review is early January • Need to have: • significant portions of TDR written • schedule for completion of TDR • Important considerations: • Upgrade project is already baselined • Cost and schedule are set • Any modifications to such must go through a change control procedure • Basically, we must try to live up to the cost and schedule that I created years ago… • Final warning: • Can’t overemphasize the need to understand the relationships in design and schedule among various system components!

  4. DØ Online TDR • List each component of the document and note who should write it • Major divisions: • Hardware • Software utilities • Run and configuration control software • Event data path software (including monitoring) • Calibration • Controls path • Accelerator interface

  8. DØ Online TDR • Event data path sections: • Level 3 Interface • Gordon / Brown • Data Logger • (Computing Division, Gene O.) • Fritz • RIP (logging to FCC) • Stu • (RIP documentation) • DAQ monitoring • (Stu) • Gordon • Event distribution • (Computing Division) • Stan

  9. DØ Online TDR • Event data path sections (cont’d): • Event monitoring / Framework • Silvia • Stan • (Computing Division) • Event monitoring / Detector • Iain • Fritz • Event monitoring / Physics & Expressline • (Stu) • Nobu (for display)
