73. Silos cause disconnects and mismatches Backlog Information I need X PrioritiesTools Backlog I do X Requests for X Silo A Information Priorities Silo B Tools Context Context Process Process Tooling Tooling Capacity Capacity

74. Function A Function B Function C Becomes siloed labor pools of functional specialists Requests fulfilled by semi- manual or manual effort Primary management focus is on protecting team capacity

75. How do we cover for our silos disconnects and mismatches? Silo A Silo B

76. How do we cover for our silos disconnects and mismatches? Silo A Silo B Ticket Queue

77. ?? Silo A Silo B We all know how well that works Ticket Queue

78. Ticket queues are an expensive way to manage work Ticket Queue Queues Create… Longer Cycle Time Increased Risk More Variability More Overhead Lower Quality Less Motivation Adapted from Donald G. Reinertsen, The Principles of Product Development Flow: Second Generation Lean Product Development

79. Tickets queues become “snowflake makers” ?? Silo A Silo B Ticket Queue

80. Tickets queues become “snowflake makers” ?? Silo A Silo B Ticket Queue Snowflakes (each unique, technically acceptable but unreproducible and brittle)

81. Silos + Ticket Queues = Locked into a broken system Unreproducible Snowflakes More Outages Longer Lead Times / Unpredictibility Siloed Labor Pools Ticket Queues Diminished Labor Capacity Brittle Environments Errors Error-Prone ManualTasks Interrupt project work Information Mismatches / Miscommunication Silo-Specific Optimization Handoffs With Capacity, Pace, Priority Mismatches “Managing to the Queue” Working out of Context “Align by Functional Capability” Management Strategy

82. Excessive toil prevents fixing the system

83. Excessive toil prevents fixing the system “Toil is the kind of work tied to running a production service that tends to be manual, repetitive, automatable, tactical, devoid of enduring value, and that scales linearly as a service grows.” -Vivek Rau Google

84. Excessive Toil prevents fixing the system Toil Engineering Work E.W.Toil Reduce toil Improve the business ǡ No capacity to reduce toil No capacity to improve business Toil at manageable percentage of capacity Toil at unmanageable percentage of capacity (“Engineering Bankruptcy”)

86. So what can we do differently?

87. Obvious: Get rid of as many silos as possible Old Silo A Old Silo B Old Silo C Old Silo D

88. Old Silo A Old Silo B Old Silo C Old Silo D Cross-Functional Team 1 Cross-Functional Team 2 Cross-Functional Team n Obvious: Get rid of as many silos as possible “Horizontal” shared responsibility is key feature!

89. But what about the cross-cutting concerns? Old Silo A Old Silo B Old Silo C Old Silo D Cross-Functional Team 1 Cross-Functional Team 2 Cross-Functional Team n Specialist Capabilities Specialist Capabilities Specialist Capabilities
