high level solution design document template

Relating to information structure is information flow. 2. In my first post on cloudelicious, I write about the importance of planning, going through required decisions and capturing those decisions and cornerstones in a documentation. A high-level design document (HLDD) describes the architecture used in the development of a particular software product. For example, if we had chosen to have a manual business process for billing rather than an automated application process. Helpful. We create structures that make sense in the context of what we are producing. High level deign gives the overview of the development of … For example you may address processes and roles in many different views. It also helps the project team in focusing efforts and ensures alignment. Sometimes the choices we make do not appear to make sense. This blog addresses this question. If you ever have to bring a High Level Design (HLD) to me for review – this blog is a good read because it sets a level of both design and review expectations. [/vc_column_text][vc_column_text]It is straightforward, a design will typically be considered good if it fulfills the requirements in a meaningful way. A picture is worth a thousand word – Pictures or diagrams are an excellent tool for visualizing a design, but they cannot convey the motivation behind a design decision. This may be small if a service is provided by a third party – because then you are only defining the business interface – but regardless we need a complete picture. CQSIM Low-Level Design Document Ren Dongxu 1 / 50 CQSIM Low-Level Design Document Ren Dongxu 1. | The solution Design Part 2 | The solution Design - The transition process | The Solution Design - Add Masking The Solution Design Document. Again remembering each view tells a story it may make sense to group together several services in the same service realization view if several services are realized in the same way – or if theres another logical reason to do so. Instead, add a footnote and refer to the online article for people who maybe don’t have the required background. Thats Ok. And a list of milestones Event can be job submit/job finish, monitor event or other event added by the user. The final document should be delivered in an electronically searchable format. Pingback: Modelling Information Flow In ArchiMate - The EA SandboxThe EA Sandbox, Designing Architecture Through Document Templates, Modelling Information Flow In ArchiMate - The EA SandboxThe EA Sandbox, Conceptual Architecture – Is a single view that sets the scope of the architecture at the highest level of abstraction. Separate details from content – Details such as a list of server names, or IP Addresses make a design document unnecessary long and hard to read. We are not using our architecture tools to produce diagrams, we are using them to produce views of architecture. 0. This document is a template for creating a High-Level Technical Design for a given investment or project. Solution Approach For Design & Development CDN Solutions Group, 304 Princes' Business Skypark, A.B. Ensure that maintaining the solution design is preserved even through role changes or organization restructures. If Microsoft reports an 64% growth in Azure sales, it doesn’t mean its partners see the same growth. ADDIE – Design | Instructional Design Document Instructional Design Document ADDIE (Analyze, Design, Develop, Implement, Evaluate) Analysis High Level Items Objective Notes What would you like the official name for this course to be? Posts usually go live on a Wednesday. Theres a lot of things that go into any architecture design and this is only one approach to creating one. A design document is a way to communicate to others what the design decisions are and why the decisions taken are right decisions. This document supersedes any previous design documents. I recently wrote about Architecture Concerns and will not go into too much detail. INTRODUCTION 1.1 Goals An event driven job schedule Simulator scans the event sequence and do the operation related to every event in time order. 3. The approach in the blog isn’t perfect, but its one I have developed and used over time to meet the requirements placed upon me by various stakeholders. If we have 100 requirements for an application by all means group them together, and put them in a single element, but only if it makes sense to do that, and you can show in other documentation how each requirement is handled separately. Growth and profit are influenced by many factors including how fast you can get an idea from idea to realization, and how well your solution can be scaled. The view gives context to some data objects that would need to be defined in the implementation views. Cisco High Level Design Hi All, Long story short my boss has asked me to utilize a MPLS link we have for our customers at a regional site, rather than just using it for customer wifi, he asked how can we get the most out of this 100 MB link. Normally I prefer to deal with architecture at a service level but there are times where thats not practical. If the document can transport this message, your job has been accomplished well. Careful analysis and study of requirement document must be made to prepare the design document. This information should be deleted from your document. I normally break architecture down into 3 basic levels. In my Planning Work With Archimate blog i talk a bit about creating motivation views for stakeholder concerns, and I also show a level of motivational modelling in my User Stories blog. 2. a High Level Design can be produced completely in an Archimate model, or maybe part of a document (I discuss this in Designing Architecture Through Document Templates. Our High Level Design is telling a story. in an archimate model: We will walk through this bit by bit. However, an excellent approach is to start with a motivational view, to create some requirements realization views from that where i figure exactly which services and processes I need to put in place to meet the requirements. It should appear in a implementation and migration view. If you don’t have a clearly defined business case, then you cannot know that any technical design or service design will be fit for purpose. When looking at HLD’s I normally like to see both of these views – however sometimes I find application cooperation and service realization views have a little bit of overlap when people model these views. Download the above template and use it as a framework to start tracking your SAP Customer Data Cloud solution. “We need to make a lot of profit” may be a true statement – but “we will make 1 million Euros in the first year” – is a lot more clear. If we are creating an entire high level design in ArchiMate you have to remember to document the model. Views. For those of you that do not know where to start I present to you a minimum set of views to consider. There may be multiple parts – such as several prerequisite documents, but they need to be referenced together in one place. Our tools enable us to document the architecture view, to explain what we are showing, as well as the elements and relationships. Formats of Design Documents The design document can take various formats or layouts. As a rule of thumb if i have more than 30 elements in a view i am asking myself if I need to split it into sub views. This section should include a high level description of why this System Design Document has been created. There might be a good reason – like not having resources to do the automation, or maybe the billing is only once a year and a 2 minute job in another system and doesn’t justify the expense. Learn how your comment data is processed. Since this is a high-level document, non-technical language is often used. If you’re following Waterfall, on the other hand, this could be a Business Requi… We link small and large data transfers across the globe into a unified solution. I already described the order i do things in normally because its the quickest way to deliver some value in my particular case. These views show basic information structures/taxomomies relating to the architecture. This Excel template works very well for larger projects with multiple tracks or sub-projects. other elements just supporting the story of how a need (driver) leads to a set of requirements that will achieve a goal. Where i currently work i normally track all decisions relating to a specific architecture on a single page so its easy to follow. Take a look at my blog on Requirements Realization Views if you are interested in going into more detail. How the process connects to the rest of the architecture, What the possible outcomes of the process are, Which roles or people provide the process. This role can either be an individual or a team. There may be reasons why you wish to use other views, or deviate from this structure. Borrowing from TOGAF – Business, Data, Application, Technology, we need to ensure we describe these layers of information. A design document is following similar patterns and if you have a structure which works for you, keep it and enhance it during the next project or update. I talk about how you might approach this in my Modelling Information Flow In Archimate blog. Figure 1 showed a simple information structure in the business layer, but of course we can create information structure views in the Business, Application and technology layers, or structures to show how they are related. Sometimes people leave positions in an organization and sometimes you never find out why. edited on: ‎07-07-2019 ‎03:02 PM . developers). Why not move this information into appendices or refer to an external document? Then I would move onto to using something like SpecFlow to create executable documentation. Stay tuned for more content, and keep it cloudelicious! In those cases related architecture may be together in a grouping box which is named something to explain what it is. An important skill for any software engineer is writing technical design docs (TDDs), also referred to as engineering design docs (EDDs). I promised a colleague I would publish this blog, so it was written in a bit of a rush and I may go back and update it later. It should appear in a requirements realisation view, It should appear in a Service realisation view. Our tools enable us to document the architecture view, to explain what we are showing, as well as the elements and relationships. For any architecture, having a defined set of requirements to validate is essential. An ABB is an Architecture Building Block. Remember to address the audience. Don’t forget to use captions for more accessible reference. I will save that for a future blog. Capture the decisions – A design document is all about decisions to meet the requirements. where I work currently normally at the point architecture begins a business person has already got a conceptual idea in their head and want to start there. Its not practical to build designs without putting them into the context of the business. Design Document, continued Sign-off Obtaining sign-off on the design document is important in ensuring agreement on the plans at this point. More detailed descriptions of the architecture and system components will be described throughout subsequent sections of the document as shown in this template.This System Design Document has been created to outline the proposed system design for new Acme Corporation Maintenance Management Sy… Of course, “there isn’t just one way of doing it”, and every customer has their requirements or preferences. Ver Date Nature of Amendment 1.0 12 Apr 2006 Initial Document 1.1 8 Jun Update Layout and style sheet 1.2 23 Nov 06 Update Layout and Style 1.3 19 Jul 2007 Update Corporate Logo If a product states it will make a million Euros per year i want to see the rationale behind that number, and to see that such numbers are realistic. For example, our best service level might necessitate us to build a technology architecture that has complete redundancy and multi site. We can see clearly that we would need to define two virtual machine templates and a standard network configuration for implementing our basic Apache – and we might chose to reuse these elements. You would use a grouping box where you might want to represent a group of elements that are cross layer. description of the product. That’s a business decision. Once the TOC is complete, add bullet-points to indicate the content that goes into these chapters. All requirements need to be shown to be managed within an architecture design. You have to know your stakeholders and ensure they all have access. Conceptual architectures can come in many forms – I am normally looking for a single view in ArchiMate that shows the concept of the business case architecture. Have a look at the tips below and understand how this could be adapted when you write your next design document for Microsoft Azure: Structure your paper – start with the table of contents with the most important chapters of the document and drill down one level after the other. After the functional design document is completed and signed off, the development team needs to start writing a technical design document. A technical design document (TDD) includes information the programmatic approach of how a particular requirement will be implemented. Like in the 3 rd example template, this one also shows the setup and the configuration of VPN instances, although there are only 2 instances here. Short documents are easier to read and lot more comfortable to maintain to keep the content up-to-date. As technical details are going to change over time, it’s even more important to build a general design as a foundation to start from. The diagram template below is of an HA design for the VPC component of the network. That blog covers the basic minimums I would expect to see in order to understand a project and its road map. This document is also intended to help detect contradictions prior to coding, and can be used as a reference manual for how the modules interact at a high level. Its important to document how information flows throughout your architecture. If we are working with ArchiMate we do not necessarily need to see every requirement on a view – its ok to group together requirements on the view to make it more manageable: The above (Figure 3) is OK- if in the documentation for those requirements you link back to a source where those requirements are all managed together – so we can easily see the working status of each underlying requirement. As an example. High Level Design – Is something in the middle. Every Service has a service realization view (Several can be part of a single view). You should always be able to list at least one compelling reason, related to the conditions, for why a design decision was made. It should also provide what the new system is intended for or is intended to replace. The technology views show how our technology layer fits together. In a non product related conceptual we make sure the view we provide hooks into the current existing architectures (services or products normally. Confidential Company Details Software Development High-End Design and multimedia: Mobile Solutions Following are our company details Company Details Company name CDN Solutions … We do not document or create views just for the sake of having them. Within the service realization I have identified a number of different application layer items (Apache & IIS) which should exist within a technology usage view. Such a decision quite often gets made in a meeting, maybe minuted and dropped into an email and forgotten about. This can take many forms (such as User Stories). Feel free to propose several options. It gives us the answers to all the fundamental questions, whilst normally staying at a level of abstraction from actual technology implementations. People are crucial to success in every project, and especially when you define the cloud platform for your servers and applications. Those mechansims are good for capturing different concerns from different stakeholders, but the important thing to note here is that we need to align the motivation model with the actual business case. Powered by Adeptia, our On-Demand Integration solution truly achieves the ability to integrate from anywhere to anywhere, pulling data from a customer site or receiving incoming data. For example I might have everything relating to application monitoring described (including its interfaces, triggers and processes) in a grouping box named “Application Monitoring”. There is a balance to be had. Important, leverage pictures to supplement a design document, not be a design document. Usually, it’s not. A good business case demonstrates the thinking behind the numbers. It is a living document and must be properly maintained. further insights on the naming convention. While probably everyone agrees with the statement, before using a new product or service in production, it’s required to have a plan in place which addresses the “why”, “what” and “where” there is usually a push-back on those planning efforts. LLD describes the class diagrams with the methods and relations between classes and program specs. Within any solution or service design there are normally many meetings, and its essential we track decisions that are made in a single space that is available for all. Its wasted time that can be easily avoided with a little discipline. 45. If you’re following Agile, Requirements Documentation is pretty much equal to your Product Backlog, Release Backlog and Sprint Backlogs. The most significant factor that determines if a design document is useful is if it clearly explains the author’s intentions. 6 min read. If we are creating an entire high level design in ArchiMate you have to remember to document the model. In a high level design we do not want to go to too much detail – Figure 6 has value because in our fictional example it shows our audience the configurations that we will need to support and helps set scope. These views are useful for seeing how application elements connect together, and how they tie into application data elements and flow of information, which is a good baseline for work with GDPR for example. To see the full list, view the Table of … Its important for all information around your architecture to be stored together. I also want to ensure as far as possible that i do not duplicate information – its better to refer to master information sources for things when required. This article can be helpful when you start your own Azure Design. If you have a suggestion for improving this document, complete and forward a copy of Suggestions for Improvements to Documentation. This site uses Akismet to reduce spam. Some of our application monitoring processes may be business related or technology related for example. The question “How Much Is Enough?” is often put to me. Figure 1 showed a simple information structure in the business layer, but of course we can create information structure views in the Business, Application and technology layers, or structures to show how they are related. normally when i am doing a review meeting i will take a copy of related documents and store them together so that there is a timeless copy that cannot be interfered with. Have a look at the article describing the different flavors of an architect; this might positively impact your staffing. Figure 3 showed a very high level view – I would expect in such a case we would also need other requirements realization views to show more detail because although figure 3 gives me a level of confidence that we are managing requirements, it doesn’t really tell me how. Following our example if we have technology devices for Apache and IIS I would want to understand how they fit together and are connected via a network. Just because a vendor has a standard reference architecture or a standard set of best practices, it doesn’t mean our job is done. We are not using our architecture tools to produce diagrams, we are using them to produce views of architecture. However, there are a few common mistakes I regularly see in projects all around EMEA, which can make the acceptance of a document difficult: What people often underestimate, a design document is like a written contract between you, your customer or manager and the project team. I want to see the following when I validate a HLD: When we talk Stakeholders its very easy to be preoccupied with just the customer or the end user but in reality many teams or people either provide something to your architecture, or require something from it. Solution Architecture Template (SAT) Design Guidelines v2.0.0 ISA² Action - European Interoperability Architecture Page 5 of 25 2 INTRODUCTION TO SOLUTION ARCHITECTURE TEMPLATES 2.1 The European Interoperability Reference Architecture The Solution Architecture Templates that are described in this document are based on the ISD / ADDIE Design Document Template 1. Keep it short – Quantity doesn’t automatically make a good document. It usually includes a diagram that depicts the envisioned structure of the software system. High Level Design Document Sample The purpose of this High Level Design (HLD) Document is to add the necessary detail to the current project description to represent a suitable model for coding. Bear in mind, this doesn’t necessarily mean that the benefit is profit. Determine who in your organization will be responsible for maintaining the solution design document. For the business processes I only want to understand: Normally this can be done a lot quicker than actually fully defining a process. The most realistic cases are based on existing numbers. There could also be related requirements realizations needed of course. I might have a simple view which shows how IIS is served by a technology device – or the scenarios could be more complex – for example we may be using virtualization. With Adeptia, integration across applications in the cloud — as a true off-the-shelf service — has been realized. If you have data elements in the Information Structure Views its good to show them here if it makes sense to. The order of things I am showing can happen in two different ways. imbashir ‎05-14-2019 02:55 PM. You eat with your eyes – The primary purpose of a design document is, of course, the technology. You most likely want to bring your A-Team to the design workshops. It does require some Excel knowledge (merging and formating cells, etc.) The important thing here is that requirements are mapped to their respective areas of architecture. Naturally, requirements are going to change sometimes. Whatever the benefit is, it needs to be stated, it needs to be clearly defined in a way that is measurable and not subject to opinion. Would be surprising, as the consultants doing the implementation usually are very knowledgeable about the technology. We have already moved through the first 6 chapters of the solution Design. The business case is basically setting the scene for what we expect from the architecture. This document includes a high-level architecture diagram depicting the structure of the system, such as the database architecture, application architecture (layers), application flow (navigation), security architecture and technology … If it states we need to hit a revenue target then these goals are part of our architecture motivation. . When you document your assumptions, decisions, risks, etc., you give others a chance to agree with the scope. This document is also intended to help I chose to use a Grouping box rather than create individual compositions to each data object. Office 365 & Exchange High Level Design Template I set up this template as a means of standardising how I deliver High Level Designs for Exchange and Office 365 to my customers. Working with requirements realization views, my key element of focus is the requirement. Low Level Design – Is architecture at its lowest level – which can include actual machine and network configurations, and exactly how things are implemented, Ensure there is version control so we know what version of a particular document or source we are referring to on our design. A design doc — also known as a technical spec — is a description of how you It basically needs to lay out what it is thats being proposed, and the value we get from it. More practically, for general software development I prefer an approach of using high level design to flesh out the overall requirements, I would recommend looking at Behaviour Driven Design to help with that. … design documentation is explaining how a feature work instead of describing a design decision; … people get lost in the details of a document and don’t find what they are looking for; … most documentation rarely is kept up-to-date as the project progresses; … people tend to forget which questions they need to answer during the writing; … the document tries to answer all questions for all possible audiences. For more complex structures we could of course use something like a UML class diagram – but most of the time the structures I use are simpler. Comments. Effectively all those prerequites we have described are setting a challenge. The high level design document must be designed by taking into account one or more of the following namely. In product service architectures i am normally showing Business Application and Technology layers, but not showing data or information flows. If an architecture isn’t providing a benefit to our business we shouldn’t be doing it. Don’t duplicate content or copy & paste text from the Microsoft Azure Documentation library. Determine where your solution document will reside. Download the Technical Design Document Template. We still have requirements that need to be realized and we still need to cover the architecture aspects when using a vendor architecture. At some point, someone will have to implement this design, so we want to make the knowledge transfer as smooth as possible. 1.2. The purpose of this High Level Design (HLD) Document is to add the necessary detail to the current project description to represent a suitable model for coding. Our product management teams are used to working in a specific way – I normally have to start by asking what is it they are trying to do, and then when I understand what – I am wanting to understand why. High level design is a subject of much discussion in pretty much every organization I have worked with. Let's look at chapter 7 - the High Level Timeline. I normally am focusing on scope. The idea of this article is to share insights from my experience how you could write a design document for Microsoft Azure, addressing the most important topics with a right balance between amount of content (amount of pages) and technical depth (level of details) / with hope that the document’s value is at its max. Its ok to reference external sources for things liike requiremetns or supporting information, but when this is done you have to consider the following. Is it because people don’t know what to write? In my blog on Aligning Archimate to BPMN – I introduced the idea of creating process overviews, such as this one: In a high level design I don’t expect to see fully defined processes. Every Service or function I have defined at the upper level needs further detailing: I do not necessarily have to see all services defined in their own service realization views, although I often will. For more complex structures we could of course use something like a UML class diagram – but most of the time the structures I use are simpler. When you have that agreement, you’re ready to move forward and develop the actual training materials. The reality is, that depending on your requirements the amount of emphasis you put into different areas of architecture radically change – for example if we are using Amazon Web Services as a provider of our technology platform we might not need to fully define that platform – although it may still need a small amount of architecture – just for us to state we use the technology level services from Amazon, and maybe what the interfaces into those services are. Consider customer requirements/user stories for our Web Hosting product: The point I am trying to make is different requirements may be realized in very different ways. 1.2 Project Overview The document is structured to initially describe the solution at a high level and progressively provide more detail to the point where all the solution requirements of each system have been detailed. A conceptual architecture for a product normally shows the product and the services within it (Like a product view), as well as showing the key application components, or technology layer components relating to the product, as well as the teams that support it, and other related products & dependencies. Why is there a “reddog” DNS Suffix for my VM’s? Networking Documents: Cisco Software-Defined Access (SDA) High Level Design (HLD) Template; Cisco Software-Defined Access (SDA) High Level Design (HLD) Template. Labels: Labels: Cisco Digital Network Architecture-DNA; LAN Switching; SD-Access; 11352. Conceptual architectures are normally a good starting point when you are in this situation, as are layered views. If you feel the complexity of the problem requires addition 'throw away' documents … Depending on how i was going to use this architecture model I might have done it the other way, but we should visualize in a way that makes sense to our stakeholders. The service realization view is showing how the business layer connects into the application layer. Working with motivations views I like to ensure i have the drivers, goals, and requirements clearly defined. Take a look at figure 6. I normally take a service focused approach to building architecture. We also probably need to establish a proper interface and set of requirements for the vendor. Take a look at my Services In Archimate blog – it shows some layered views. It doesn’t cover more complex concepts such as using plateau’s to represent different states of architecture.
