    50 75 100 2007 2009 0 50 100 150 200 2007 2009 0 25 50 75 100 2007 2010 0 17,5 35 52,5 70 0 25 50 75 100 2007 2009 7 % 8 % 10 % 11 % 29 % 35 % 0 10 20 0 5 10 15 20 2007 2008 2009 2010 0 50 100 150 200
  66. Categorize messages in Comparison Types Structure Frequency Time Series Context

  67. A structural comparison contains procentual or proportional information in the

    message 27% of the reported errors were in the user interface whereas only 4% could be allocated to the business logic 9 % 60 % 4 % 27 % UI Business 3rd party libs Other
  68. A frequency comparison aims to show how often a figure

    appears in different magnitudes Most of the bugs are CSS layout bugs 0 15 30 45 60 DB JS CSS Java
  69. A time series comparison documents the change of a figure

    over a certain amount of time „We managed to lower our build times by 45% within the last 30 weeks by introducing Gradle “ 0 25 50 75 100 0-10 10-20 20-30 AVG Build Time
  70. A contextual comparison displays data in context to each other

    an aims to deduce correlations „Too many queries are executed too often in relation to their runtime“ 0 100 200 0 100 200
  71. A Ranking evaluates data in order to deduce a order

    of precedence „Most of the developers in our team favor Apache Wicket whereas JSF is not very popular“ 0 15 30 45 60 JSF GWT Wicket
  72. Visualization of textual facts with Slides

  73. Structure Display of structure within layers, trees or a matrix

  74. Cluster Display of grouped information

  75. Flow Display of processual flows

  76. Radiate Display of correlations, knots and cores

  77. Influence Display of cause and effect

  78. Don‘t manipulate

  79. Step 5: Performance
