This approach provides customers with product progress quickly and the development team with feedback on each layer behind a feature. You need both horizontal and vertical thinking for your project.Īgile focuses on vertical slices, allowing your team to quickly deliver value. Similarly, if each slice is a story used to plan your software architecture, then there are layers- slicing the cake vertically creates stories centered around individual features, while slicing horizontally reveals individual components. Cakes can also be sliced horizontally, separating individual layers. That vertical slice has a little of everything. Let’s say a full slice has frosting, filling, and two or three layers of sponge cake inside. Most people slice a cake vertically, through each layer. It’s helpful to think about slicing a cake. Dividing your architecture into slices can help you craft this plan in a way that delivers value to users and appropriately plans your use of development resources. Your architecture design, naturally, moves into a planning phase as you decide how you’ll deliver on your design. Wait and design the final architecture later: In all likelihood, your architecture planning will change throughout this process, so don’t expect the first draft to resemble the final result. First, you want to look at what your requirements imply for your design-for instance, where individual items from your stakeholder wish list may contradict each other or be in conflict with other functional and non-functional requirements. Start with a “perfect world”: What would your design look like if you could create it perfectly?Ĭonsider and document the implications of your requirements: Start a working draft with your team and develop it gradually. Some requirements may actually be impossible under certain assumptions or choices. Without getting too far ahead of yourself thinking about implementation, you’ll need to find out which requirements pose significant challenges to your design or your project plan. Let’s face it-with the powerful influence your functional requirements have on your project, your design and technology options may be already decided once you’ve mapped out your requirements. Your requirements should be used to shape your scope of work and plan out your project. A requirement like “performance” is key but is probably too abstract to place on the mind map. For example, verbs such as “view” and “edit” can link “account” or “profile” to each other in a mind map of functional areas.Ĭonsider non-functional requirements: While you’re working on your mind map, you can jot down your non-functional requirements for later. Map your functional requirements: You can use verbs to help you cluster nouns together. Mind mapping is an effective way to do this. Start with a high-level view: Sketch out your requirements at a “helicopter view” first. Gain a better understanding through visuals-follow these steps to map out your requirements in an intelligent diagramming platform like Lucidchart: Without a clear understanding of these requirements from the beginning, your team runs the risk of getting lost, emphasizing the wrong requirements at the expense of others, or using an inefficient amount of internal resources. These requirements guide your software architecture along and allow you to finish the project with an end product that your stakeholders are satisfied with. Have a clear understanding of your requirementsĮvery design you embark on will have both functional and non-functional requirements. How to design software architecture in 5 steps 1. Software architecture design uses programming knowledge to plan the high-level design of software so that detail can be added later, allowing software teams to sketch out the big picture and begin preparing a prototype.īy following software architecture design tips and best practices, software developers can think through their software’s characteristics and determine how to design software architecture. Using technical visuals and a careful planning process, you can outline your software architecture and design before you get started on a prototype. By making this process more effective, you can account for all of your requirements properly and give stakeholders the opportunity to provide their input. You wouldn’t want to jump into a project without a solid plan, and software architecture design is no different.
