high level solution design document template

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. We also probably need to establish a proper interface and set of requirements for the vendor. It describes the modules so that the programmer can directly code the program from the document. For example I might have everything relating to application monitoring described (including its interfaces, triggers and processes) in a grouping box named “Application Monitoring”. I am fine with the idea of reusing with pride; several vendors have standard reference architectures. The scope of the work required for the project to be completed. “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. Remember just as with our conceptual an architecture has to address architecture aspects. At some point, someone will have to implement this design, so we want to make the knowledge transfer as smooth as possible. Is it because people don’t know what to write? 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. 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… An ABB is an Architecture Building Block. 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. The important thing here is that requirements are mapped to their respective areas of architecture. We can lay out the relationships between the data elements and can even document the relationships to explain why they exist. Some of our application monitoring processes may be business related or technology related for example. developers). Take a look at figure 6. imbashir ‎05-14-2019 02:55 PM. Creating a high-level schedule with only key activities and milestones is a very powerful communication tool. 2. 3. Its wasted time that can be easily avoided with a little discipline. Don’t the comments below somehow sound familiar? Thats Ok. Determine who in your organization will be responsible for maintaining the solution design document. To see the full list, view the Table of … I chose to use a Grouping box rather than create individual compositions to each data object. I normally start with a conceptual view and then refine and define services from there. High level deign gives the overview of the development of … Implementing a High Level Design, as described here goes a long way towards creating a solid design that mitigates risks and significantly reduces cost to business. 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. When you document your assumptions, decisions, risks, etc., you give others a chance to agree with the scope. 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. 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. Posts usually go live on a Wednesday. 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. 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. 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. It is a living document and must be properly maintained. Once the TOC is complete, add bullet-points to indicate the content that goes into these chapters. Conceptual architectures are normally a good starting point when you are in this situation, as are layered views. You most likely want to bring your A-Team to the design workshops. This information should be deleted from your document. Of course, “there isn’t just one way of doing it”, and every customer has their requirements or preferences. That reason must be kept and documented. 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. Networking Documents: Cisco Software-Defined Access (SDA) High Level Design (HLD) Template; Cisco Software-Defined Access (SDA) High Level Design (HLD) Template. 0. CQSIM Low-Level Design Document Ren Dongxu 1 / 50 CQSIM Low-Level Design Document Ren Dongxu 1. There is a balance to be had. If we are creating an entire high level design in ArchiMate you have to remember to document the model. Take a look at my Services In Archimate blog – it shows some layered views. A good business case demonstrates the thinking behind the numbers. The most significant factor that determines if a design document is useful is if it clearly explains the author’s intentions. It basically needs to lay out what it is thats being proposed, and the value we get from it. For example, our best service level might necessitate us to build a technology architecture that has complete redundancy and multi site. 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. description of the product. You have to know your stakeholders and ensure they all have access. 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. High-level design document A high-level design document or HLDD adds the necessary details to the current project description to represent a suitable model for coding. I normally break architecture down into 3 basic levels. We are not using our architecture tools to produce diagrams, we are using them to produce views of architecture. Take a look at my blog on Requirements Realization Views if you are interested in going into more detail. 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. 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. There may be reasons why you wish to use other views, or deviate from this structure. 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. For any architecture, having a defined set of requirements to validate is essential. In our web service hosting example, our business service might be realized by two different application components – Apache & Internet Information Server (IIS).The view shows how this service is provided. 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. other elements just supporting the story of how a need (driver) leads to a set of requirements that will achieve a goal. It can mean different things to different people, teams, projects, methodologies. 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. However, why is it so difficult to find a good design document? Low-level design is created based on the high-level design. After the functional design document is completed and signed off, the development team needs to start writing a technical design document. With Adeptia, integration across applications in the cloud — as a true off-the-shelf service — has been realized. This document is also intended to help 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. This document supersedes any previous design documents. I will save that for a future blog. 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. New articles are released when we have something new and unique to say. Event can be job submit/job finish, monitor event or other event added by the user. I already described the order i do things in normally because its the quickest way to deliver some value in my particular case. If an architecture isn’t providing a benefit to our business we shouldn’t be doing it. Bear in mind, this doesn’t necessarily mean that the benefit is profit. From kick-off to project completion, describe the desired project timeline … If Microsoft reports an 64% growth in Azure sales, it doesn’t mean its partners see the same growth. Since this is a high-level document, non-technical language is often used. Theres a lot of things that go into any architecture design and this is only one approach to creating one. Such a decision quite often gets made in a meeting, maybe minuted and dropped into an email and forgotten about. A design doc — also known as a technical spec — is a description of how you Keep in mind that the document was created to be customized and leveraged by technical resources (i.e. 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. Its ok to reference external sources for things liike requiremetns or supporting information, but when this is done you have to consider the following. If you have data elements in the Information Structure Views its good to show them here if it makes sense to. That’s a business decision. LLD describes the class diagrams with the methods and relations between classes and program specs. I talk about how you might approach this in my Modelling Information Flow In Archimate blog. We create structures that make sense in the context of what we are producing. Download the above template and use it as a framework to start tracking your SAP Customer Data Cloud solution. The most realistic cases are based on existing numbers. If we are creating an entire high level design in ArchiMate you have to remember to document the model. I talk about modelling projects in my blog Planning Work In Archimate. Confidential Company Details Software Development High-End Design and multimedia: Mobile Solutions Following are our company details Company Details Company name CDN Solutions … Our lowest service level may be a single server in a data center. 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. 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. 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. As an example. When assessing business cases I am normally looking to see also the reason behind the numbers. … 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. Have a look at the Table of Content (TOC) below; it highlights the most important topics to include in a design document for Microsoft Azure: You can find further insights on the naming convention for Azure Resources in our next blog post. Have a look at the article describing the different flavors of an architect; this might positively impact your staffing. If you have a suggestion for improving this document, complete and forward a copy of Suggestions for Improvements to Documentation. 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. I’ve had many engineers ask me for guidance on this. 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. Ensure that maintaining the solution design is preserved even through role changes or organization restructures. Road, Indore 452010, India, Skype:cdnindia www.cdnsol.com | www.cdndesignstudio.com | www.cdnmobilesolutions.com . 45. The diagram template below is of an HA design for the VPC component of the network. Don’t forget to use captions for more accessible reference. 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. Working with requirements realization views, my key element of focus is the requirement. There may be multiple parts – such as several prerequisite documents, but they need to be referenced together in one place. Its not practical to build designs without putting them into the context of the business. 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. This article can be helpful when you start your own Azure Design. If you can’t come up with an apparent reason for a design decision, then it is probably not adding enough value. It is vitally important that decisions are tracked in a work log and not just in a meeting; I have seen thousands of hours burned because of a decision not being tracked and then trying to track back with the relevant people how and what was decided. If you feel the complexity of the problem requires addition 'throw away' documents … 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. 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. 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? 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. 6 min read. Model the common scenarios. This Blog went live in March 2018. Every Service has a service realization view (Several can be part of a single view). The technology views show how our technology layer fits together. I normally am focusing on scope. 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. Feel free to propose several options. ISD / ADDIE Design Document Template 1. People are crucial to success in every project, and especially when you define the cloud platform for your servers and applications. Relating to information structure is information flow. Usually, it’s not. 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.
