Defining Requirements – The TOGAF Way

How is it different?

If you are new to TOGAF, you may be wondering how this process is different from what you do in a typical “Requirement Analysis” phase of software development. Once I tell you that the many of the techniques recommended in TOGAF are what you are already using, like UML modeling techniques like Activity Models, Use-Case Models and Class Models, you may think why bother with TOGAF?

What you really do differently in TOGAF is that you take a much wider perspective of the requirement. There are three important things that you need to do:

  1. Explicitly document the current state, the expected future state and identify the gap
  2. Assess impact of the change on other projects and other organizational initiatives
  3. State the change from the perspective (viewpoint) of different stakeholders and get their buy in

While doing this, you need to keep in mind the following:

  1. Are you adhering to all the relevant organizational standards & guidelines?
  2. Have you made an explicit attempt of reuse?

Steps for Defining the Requirement

We had discussed the following lists (without the 3 steps in “Define Requirement”) in my earlier posts –
What is TOGAF? & Planning a project.

  1. Tailor TOGAF to suit your need
  2. Define scope of work and prepare plan for rollout
    1. Define the scope and get approval from the sponsor
    2. Define requirement in terms of how the business process will change, what data, application and technical infrastructure is required for accomplishing the work
      1. What should the new business process be?
      2. What application & data do we need to support the changed process?
      3. What technology infrastructure do we require to implement the change?
    3. Select a suitable solution and make the implementation plan
  3. Oversee development and implementation
  4. Manage post-implementation change

What about defining Services? The SOA approach? TOGAF has some recommendations but it looks more like a force fit - we will cover it later.

Here are some of the terminologies used in TOGAF and their meaning as used in TOGAF.

View & Viewpoint

  • View = What you see or what a stakeholder sees
  • Viewpoint = Model or description of the information contained in a view

Baseline, Target & Gap

  • Baseline = Where you are now
  • Target = Where you want to be
  • Gap = What needs to change

Deliverable & Artifact

  • Deliverable = Contractually specified document – formally reviewed, agreed, and signed off by the stakeholders
  • Artifact = Architecture from a specific viewpoint – can be a Catalog, a Matrix or a Diagram

Thomas Bitman of Gartner wrote a blog post last year about why OpenStack projects fail. In that article, he outlined three particular metrics which together cause 60% of OpenStack projects to fall short of expectations: Wrong people (31% of failures): a successful cloud needs commitment both from the operations team as well as from "anchor" tenants. Wrong processes (19% of failures): a successful cloud automates across silos in the software development lifecycle, not just within silos.
Node.js and io.js are increasingly being used to run JavaScript on the server side for many types of applications, such as websites, real-time messaging and controllers for small devices with limited resources. For DevOps it is crucial to monitor the whole application stack and Node.js is rapidly becoming an important part of the stack in many organizations. Sematext has historically had a strong support for monitoring big data applications such as Elastic (aka Elasticsearch), Cassandra, Solr, S...

As the world moves toward more DevOps and Microservices, application deployment to the cloud ought to become a lot simpler. The Microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. Serverless computing is revolutionizing computing. In his session at 19th Cloud Expo, Raghav...
Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resource...

The following fictional case study is a composite of actual horror stories I’ve heard over the years. Unfortunately, this scenario often occurs when in-house integration teams take on the complexities of DevOps and ALM integration with an enterprise service bus (ESB) or custom integration. It is written from the perspective of an enterprise architect tasked with leading an organization’s effort to adopt Agile to become more competitive. The company has turned to Scaled Agile Framework (SAFe) as ...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...
A company’s collection of online systems is like a delicate ecosystem – all components must integrate with and complement each other, and one single malfunction in any of them can bring the entire system to a screeching halt.
