If a Feature misses a timed departure and does not get planned into the current PI, it can catch the next one.<\/li><li>A new system increment every two weeks \u2013 Each train delivers a new system increment every two weeks. The System Demo provides a mechanism for evaluating the working system, which is an integrated increment from all the teams.<\/li><li>Synchronization is applied \u2013 All teams on the train are synchronized to the same PI length (typically 8 \u2013 12 weeks) and have common Iteration start\/end dates and duration.<\/li><li>\u00a0The train has a known velocity \u2013 Each ART can reliably estimate how much cargo (new features) can be delivered in a PI.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/li><li>Agile Teams \u2013 Agile Teams embrace the \u2018Agile Manifesto\u2019 and SAFe Core Values and Principles. They apply Scrum, Extreme Programming (XP), Kanban, and other Built-In Quality practices.<\/li><li>Dedicated people \u2013 Most people needed by the ART are dedicated full time to the train, regardless of their functional reporting structure. <br \/>Face-to-face PI Planning \u2013 The ART plans its work at periodic, mostly face-to-face PI Planning events.<\/li><li>Innovation and Planning (IP) \u2013 IP Iterations occur at the end of every PI and provide an estimating guard band (buffer) as well as dedicated time for PI planning, innovation, continuing education, and infrastructure work. <br \/>Inspect and Adapt (I&amp;A) \u2013 An I&amp;A event is held at the end of every PI. The current state of the solution is demonstrated and evaluated. Teams and management then identify improvement backlog items via a structured, problem-solving workshop.<\/li><li>Develop on Cadence, Release on Demand \u2013 ARTs apply cadence and synchronization to help manage the inherent variability of research and development. However, releasing is typically decoupled from the development cadence. ARTs can release a solution, or elements of a solution, at any time, subject to governance and release criteria.<\/li><\/ul><p>\u00a0<\/p><p>Additionally, in more significant value streams, multiple ARTs collaborate to build more extensive solutions via a Solution Train. Some ART stakeholders participate in Solution Train events, including the Pre- and Post-PI Planning and Solution Demo.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-965c965 elementor-widget elementor-widget-heading\" data-id=\"965c965\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">ARTs are Organized Around Value<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-80404d8 elementor-widget elementor-widget-text-editor\" data-id=\"80404d8\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>ARTs are typically virtual organizations that have all the people needed to define, deliver, and operate the solution.

While there are reasons why organizations have evolved that way, the value doesn\u2019t flow quickly, as it must cross all the silos. The daily involvement of managers is necessary to move the work across these silos, and as a result, progress is slow, and handoffs and delays rule. Instead, the ART applies systems thinking (SAFe Principle #2) and organize around value (SAFe Principle #10) to build a cross-functional organization that is optimized to facilitate the flow of value from ideation through deployment and release, and into operations, as Figure 3 illustrates.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d4bea91 elementor-widget elementor-widget-image\" data-id=\"d4bea91\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"472\" src=\"https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Agile_Release_Train_F03_WEB-2.png\" class=\"attachment-large size-large wp-image-4196\" alt=\"\" srcset=\"https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Agile_Release_Train_F03_WEB-2.png 800w, https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Agile_Release_Train_F03_WEB-2-300x177.png 300w, https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Agile_Release_Train_F03_WEB-2-768x453.png 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Figure 3.

Otherwise the potential benefits of creating ARTs that can deliver a continuous flow of value will be lost, as the teams struggle to manage the various dependencies and interconnections between them.<\/p><p>To simplify this job of team design, SAFe applies four fundamental team topologies [1] which are defined as follows:<\/p><ol><li>Stream-aligned team \u2013 organized around the flow of work and has the ability to deliver value directly to the customer or end user.<\/li><li>Complicated subsystem team \u2013 organized around specific subsystems that require deep specialty skills and expertise.<\/li><li>Platform team \u2013 organized around the development and support of platforms that provide services to other teams.<\/li><li>Enabling team \u2013 organized to assist other teams with specialized capabilities and help them become proficient in new technologies.<\/li><\/ol><p>Each of these team topologies maps to a specific set of responsibilities and behaviors, and together they provide a clearer and better model for organizing Agile teams in SAFe. Further information, as well as guidance for applying these topologies, can be found in the Agile Teams article.<\/p><p>When designing ARTs, and the teams that compose them, it can also be useful to visualize these teams in terms of the topologies that they map to. In order to make the team types clear, we use the following icons, shown in Figure 5, to represent the different team types. A stream-aligned team is represented with an arrow on the end, emphasizing flow, a square is used to represent a complicated subsystem team, a rectangle for a platform team, and a dotted ellipse for an enabling team.<\/p><p>These icons can also be used to visualize the likely interactions between the teams through their relative positioning. The names of the specific teams can then be added to these icons for a complete picture. Visualizing the teams on the ART in this manner helps to compare and contrast the merits of competing designs and also provides an indication of how well any particular design is aligned to the flow of value.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ee7f2b1 elementor-widget elementor-widget-image\" data-id=\"ee7f2b1\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"322\" src=\"https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Team_Topologies_F02_WEB.png\" class=\"attachment-large size-large wp-image-4205\" alt=\"\" srcset=\"https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Team_Topologies_F02_WEB.png 800w, https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Team_Topologies_F02_WEB-300x121.png 300w, https:\/\/www.scrum.cn\/en\/wp-content\/uploads\/2022\/04\/Team_Topologies_F02_WEB-768x309.png 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Figure 5.
