Project planning and monitoring • Need to show feature definition timescales: • When will a particular feature be fully defined? • When will its test specifications be available? • Manufacturers need to know: • When is it safe to introduce products to the market? • Network operators need to know: • When will equipment be available to start trials? • When will products be available for commercial supply? • When can we introduce service?
Project planning and monitoring • No attempt at project control ! • Standardization activity is “contribution-driven”. • It will proceed at the pace its active member organizations wish it to. • It is not appropriate for the Support Team to attempt to control progress. • It is appropriate for the Support Team to collate information and present it so that participating organizations can: • easily determine the current state of progress; and • therefore take actions to direct their contributions in appropriate areas.
Project planning and monitoring • The Support Team maintains a project plan showing features and subordinate building blocks and work tasks, together with their estimated schedules. • An industry-standard project management tool is used, allowing participants to download the file and run simulations for their own internal calculations – “what-iffing”. • The project plan is updated as a result of progress in working groups and TSGs, with approved checkpoints each TSG-SA meeting.
Each feature is recorded. Each feature can be expanded to show its component building blocks and work tasks. Its overall time scale is shown.
For each entry, supplementary information is recorded. Hyperlink to detailed description of the feature. Intended Release in which the feature will be introduced. The lead TSG / WG. Whether it has components in more than one Release. The current degree of completion. Rapporteur. Notes.
Project planning and monitoring • How can one tell when a feature is complete? • When all its component building blocks are complete. • How can one tell when a building block is complete? • When all its component work tasks are complete. • How can one tell when a work task is complete? • When the responsible working group says so!
Project planning and monitoring • “Freezing” a Release • When all new functionality is defined. • Does NOT imply that all specs are actually available! • But remaining specs are scheduled to be completed within a “reasonable” time.
Project planning and monitoring • “Freezing” a Release • Typically, specs will be stable within three to six months of the Release freeze date (as announced by the TSGs). • But test specs and O&M specs may be six months later still.
Project planning and monitoring • How does one implement a new feature? • By modifying equipment to comply with all the Change Requests (and new specs) related to that feature.
Influencing the work 3GPP is contribution driven… • All progress is the result of contributions… • Progress can be accelerated by more input… • New Features may be proposed by 3GPP Individual Members, so… • Make sure your company participates in 3GPP
