If you\u2019d like to see this in action, ask a product architect what they are working on, they will head to the nearest whiteboard and begin drawing boxes and arrows decomposing the system they are working on. To further simplify they will organize the components into an architecture (an architecture is an arrangement)<\/p>\n\n\n\n<p>This product decomposition is important for a variety of reasons\u2026<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Helps us communicate about the product<\/li><li>Organize the design<\/li><li>Describes what needs to flow between design elements<\/li><li>Provides infrastructure for product decisions<\/li><\/ul>\n\n\n\n<p>\u2026this architecture forms the critical communication mechanism for telling everyone where we need to go and how we are going to get there. These product architects perform the same function as a building architect; i.e. they understand what the customer needs, make decisions on how to meet those needs and communicates those decisions through a set of blueprints. We could never imagine starting a building without a set of blueprints, but often product development is started without a complete set of architecture specs, which means there is no leadership on the project; so we shouldn\u2019t be surprised when we get something out that we didn\u2019t want.\u00a0\u00a0Back in the late 90\u2019s, we did analysis into runaway projects (projects over budget, out of control) at a high-tech company, we found that unless we kept the architects ahead of the construction crews, there was a 70% probability of a project runaway. When a runaway happens, the architects go into catchup\/documentation mode. This would be like an architect walking around the construction site documenting what the construction crews were building rather than leading the way with a set of specifications.<\/p>\n\n\n\n<p>So how do you know if you have good architecture?\u00a0That\u2019s a large topic by itself, but we can point out some symptoms of bad architecture\u2026<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>Architecture that follows documentation structure&#8211;system spec\u2019s, sub-system specs, etc. This often happens in highly regulated industries where you are expected to deliver a set of documents with your design. <a title=\"Stealing wheelbarrows... \" href=\"https:\/\/community.plm.automation.siemens.com\/t5\/Teamcenter-Blog\/Requirements-Engineering-What-wheelbarrows-and-requirements-have\/ba-p\/412730\" target=\"_self\" rel=\"nofollow noopener noreferrer\">This often leads to confusion about what your product is\u2014given you spend so much time on documentation you begin to think the documentation is your product.<\/a><\/li><li>Conway\u2019s Law: Mel Conway (some 50 years ago) noticed that product architecture had a tendency to match the organization structure.<br>Dr. Kim Clark\/Dr. Steven Wheelwright from Harvard Business School noticed this as well in organizations they were analyzing for their case studies\/books on Revolutionizing Product Development <a href=\"#4%20v2.docx\" target=\"_blank\" rel=\"nofollow noopener noreferrer\" name=\"_ednref2\">[ii]<\/a>and used that to predict product issues. For example if the doors of a vehicle were designed in a different part of the organization than the chassis you could predict with some likelihood that the vehicle will have leaky doors. I attended a lecture by Dr. Wheelwright where he described how they could predict next year\u2019s product problems with a high probability. Although it was gratifying how right they were, it was like watching a train wreck because of the systemic nature of the problem&#8212;i.e. organization change was required to avoid the problem.<\/li><li>Disconnected architecture\u2014whether in documents or diagrams\u2014if an architecture doesn\u2019t track the changes, variation, product configuration, etc. we end up with a architecture view that is obsolete as soon as you print it (we know something is going to change somewhere).<\/li><\/ol>\n\n\n\n<p>\u2026thus the importance of an integrated architecture that represents the cross-product arrangement and interfaces needed to pull off the reason you are creating the product.<\/p>\n\n\n\n<p>While working on one project, I was the designee to deliver bad news in a project review\u2026 After the swearing was over, the program manager put it this way, \u201cthis is like driving a car looking thru the rear view mirror, I can see the problem after I\u2019ve run over it.&nbsp;Why don\u2019t you give me something I can see the problem coming and adjust my trajectory to avoid the problem\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image alignnone\"><img decoding=\"async\" src=\"http:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/14\/2019\/09\/dinosaur-mirror-1.jpg\" alt=\"Familiar meme from Jurassic Park\"\/><figcaption>Running a project without integrated architecture like driving looking thru the rear-view mirror&nbsp;<\/figcaption><\/figure>\n\n\n\n<p>An integrated architecture will do just that; it represents an agreement of where we are going, integrated with the lifecycle should give us constant visibility into it.
