Converting to Fusebox: asking an old CF app to FLiP* Challenges Methods Results Mark Wimer mark_wimer@usgs.gov USGS Patuxent Wildlife Research Center, Laurel MD * FuseboxLifecycleProcess
Acknowledgements • THANKS to: • Free code and advice online, especially from Hal Helms, Sandra Clark, Michael Smith, Steve Nelson, Jeff Peters, John Quarto-vonTivadar, Brian Kotek, Max Porges and the fusebox community in general • Teratech’s staff, training, hosting of MD discussion list, and willingness to host these CF conferences! • The Fusebox and Synthis forums Challenges Methods Results
Challenges • Existing application: things to change • Regular modifications • New vision of application began to build • No documentation • Minimal staff – so who is documentation for? • Starting to lose decision points of app in code • Reinvented control mechanism each time new features added Challenges Methods Results
Challenges: existing app, cont’d • What was good before considering the switch • My newer work tended to smaller file size and separated functions • I had begun to separate out a ‘controller’ (didn’t call it that though) • No documentation yet (hey…nothing to lose!) Challenges Methods Results
Weighing the options to go Fusebox • Motivation to consider it: • Several other apps in house being developed using Fusebox (one in production) • Fellow developer showed interest • No written lifecycle process in use • Fears: • Fusebox 4 relatively new (Fusebox 3 confusing) • Learning curve for ‘suite’: Fusebox, MVC, CSS, FLiP, test harnesses, etc. (all at once!) • Lots of work… but then it always is. • Seemed like an ALL or NOTHING proposition. Challenges Methods Results
Fusebox Project Life Cycle* Req. | Arch. | Build • Wireframe • HTML Prototype • Prototype + Devnotes • Sign off • Architecture + Fusedoc • Final Code (& unit testing) • Integration & Acceptance Testing * THANKS to Michael Smith @ Teratech for this Fusebox Conf 2003 slide
Methods • * • Assemble team for review • (team of clients) • Wireframes • Start building wireframes based on existing apps • Solicit comments using DevNotes • Prototypes • Prototypes screen with DevNotes, 2 rounds • Architecture: in Adalon * [Get Adalon from Synthis – my new favorite software] Challenges Methods Results
Learned from Wireframes • Better to construct them with clients in room • Our clients were distributed • DevNotes method worked, but more real-time updating of wireframes would have been better • Group brainstorming dynamic is different over web • A developer may not be the best person to build them (especially in absence of clients) • Loss of user perspective at critical early stage. Challenges Methods Results
Learned from Prototypes • Create all the screens. Do not skip steps. • Since it was existing, temptation was great to skip. • Especially dynamic sections of screens; i.e. versions of a single screen. • Challenge: global navigation, design are tough to implement early on. • But it wasn’t really early on! • Users familiar with existing application • Should have recruited more newbies. Challenges Methods Results
Learned from Prototypes • Comments on user-testing. • Either paper prototypes or real screens. • Process – is user-testing spelled out in FLiP? • Convincing others above & below that it’s worth it. • If you don’t sit and watch someone fumble with your screens IN PERSON, you’ll never “get” user-friendly. (Except you in the third row, fourth from left, of course) • Need some group discussion – in house • Bounce ideas, code review, help with testing Challenges Methods Results
Directory structure before & after Controller (by user) + Public (explore) + observer (myatlas) + reg. coordinator + proj. coordinator + administrator 13 24 1 - - 71 1 - 60 After: ~350 files Before: ~ 210 files Fusebox Nouns for model & view: Each state project is coordinated at the level of a region. Observers survey each block in a region, recorded on fieldforms. Reports: by block or species. Challenges Methods Results
Screen shots and code during session • Wireframes with DevNotes and comments • Prototypes with DevNotes and comments • Adalon diagramming – pre/post MVC • Adalon for circuit planning • Resulting Circuits – detail examples Challenges Methods Results
Questions/ your feedback • Just how badly am I abusing MVC concepts? • Suggestions on circuit arrangement? • Please find me later if you want to see and make suggestions on: • Adalon project files • Wireframes • Prototypes • Application itself Challenges Methods Results
