  • Challenge: Agile processes assume that features are flexible. Time and resources are fixed.But architecture design (UX, technical requirements, etc.) wants feature to be fixed. Time and resources are flexible.

    9. 9. Top-down Architectural Planning & Agile Implementation<br />Some UX and technical infrastructure needs to be planned because they are pervasive:<br />UX affects entire customer experience so must be designed from end-to-end.<br />Technical infrastructure can affect foundation for an entire product.<br />How can architects & UX work with agile implementation teams to create their designed solutions?<br />© 2011 Geoff H Wing<br />
    10. 10. Implementing UX Architecture<br />Implementation Teams<br />UX team<br />Release Planning Team<br />(Product Manager, Product Owner, UX architect, ScrumMaster)<br />Analyze and Prioritize Epics<br />Create UX epics<br />From UX backlog, assets & design, <br />implement UX in a release. <br />Break down <br />epics  features  stories  tasks.<br />Plan implementation of UX across future releases<br />Decide epics for each release, picking from UX backlog<br />Estimate size of epics<br />Create UX backlog (prioritized epics)<br />Ensure size of work “WIP = Work In Progress” <br />does not exceed team capacity.<br />Support the Implementation Teams:<br />Supply UX design<br />Supply UX assets<br />Assist teams in breaking epics into <br />features, stories & tasks.<br />© 2011 Geoff H Wing<br />Kanban “pull” system<br />
    11. 11. Kanban?<br />Kanban: a lean “pull” system where the UX / architect team pulls UX epics from a prioritized backlog at a rate that matches the Implementation Team’s capacity.<br />Provides visibility into UX / architectural epics that need to be done.<br />Allows UX / architect team to balance amount of UX versus Feature implementation work the Agile teams are doing.<br />Helpful for UX / architect team to be advisors to the implementation teams, rather than being implementers.<br />© 2011 Geoff H Wing<br />
    12. 12. Recommendations<br />Use Kanban approach for architecture / UX scenarios where a top-down design approach is best.<br />Enable the benefits of emergent & bottom-up agile approach by having Agile implementation teams do architecture / UX work where possible.<br />Keep architecture / UX team focused by doing things that implementation team cannot: UX design, UX assets. And by taking role as advisor to teams when they are implementing.<br />© 2011 Geoff H Wing<br />
