Agenda

  • Feature-by-Feature - Collect Ideas
    • Dependent Features / Feature-Groups

Feature-by-Feature

  • to +++ (max)
  • Product Title Display (++)
    • Essential function of the Webshop
    • Should be prioritized maximally
      • lower than pictures because fashion brand, but still high
      • Potentially Filtering based on pictures?
    • People search for names
      • Search Functionality fulfills filter functionality
  • Product Page Picture and Alternate Views Display (+++)
    • Very important for purchase decision
    • essential in increasing marketability of the products
    • strongly connected with the title display
    • Loading Time / Optimization needs to be prioritized (dep?)
  • Pricing information (+++)
    • Core Feature
  • Testing Accuracy Increase (++ to +++)
    • Previous test runs showed many problems
      • Good reason to prioritize better testing
    • As early as possible, to prevent divergence of system architecture
      • Focus on testability in architecture if postponed
  • Webshop - Page Speed Increase (+ from a time perspective)
    • > 25% leave the page if people leave the page
    • important, but should be done at the end
  • Product Quantity (+)
    • Putting multiple things in the cart works too (spam-clicking)
    • Additional Feature
  • Add to cart function (+++)
    • Core Feature
    • Customers normally order multiple things at the same time from Fashion Brands
      • Increase Sale Volume
  • Product Description Display (++)

  • Product Star Review / Ranking (+)
    • Reference Values are important for new customers
      • Other people's preferences have an important influence on the customer
    • Instagram Ads / Community Presence might be important to consider
    • Not necessarily important, because lots of people have different opinions
      • Possible alternative of the fit
        • Smaller as the size / Bigger as the size
    • Contra: Star Reviews on your own page might discourage people from buying products with low reviews

Agenda

  • Risks
  • Risk Mitigation
  • Testing Capacity?
  • Presentation

Meeting 4

Risks

  • Full Capacity Sprints at the end
    • Illness / Lower-than-expected efficiency will cause features to be delayed
    • Mitigation: Low-Priority Features reduce impact of potential delays
  • Improperly done Testing Accuracy Increase might cause major problems down the line
    • Architecture / Development Process Change ("Normal" Development -> Test-driven Development)
  • Important Features (Page Speed Increase, English Language) at the end, so they might not be completed
    • Mitigation: Irrelevant feature Live Chat at the end, so that it may be sacrificed for the more important features if the time isn't enough
  • "Related Products"-Algorithm might very well take longer than expected
    • Mitigation: Fourth Sprint, so that a One-Sprint Delay won't impact the schedule
  • A subpar implementation of all picture-related tasks might impact site loading times negatively
    • Mitigation: Standardize Image Resolution to a reasonable level, Page Speed Increase at the end so that problems can be found then
  • Feature Size might be wrongly estimated
    • Mitigation: Non-full capacity sprints at the start, big but irrelevant feature "Chatbot" at the end as a kind of buffer
  • Effort to implement Social Share Buttons is probably heavily overestimated
    • No mitigation necessary, as it might free up some time to be done earlier on
  • Improper Test Cases
    • No mitigation possible
