Agile Methodology
Why on earth would this BOK be into existence when there are loads and loads of documentation available on company archives that we can refer to during crunch times. So, Am I reinventing the wheel? No way. The below bulleted matrix would help you keep afloat in case you hit the agile monster or have butterflies in your stomach about Agile based projects and its future. So, is Agile Immortal? Humm ……….let me think. Well Almost for the current era. Agile is a way for product companies to substance their lively hood by ensuring they power pack their software products by business driven factors which we know as requirements, enhancements, UI features, and bug fixes. Agile is a way to build software using the small optimized revisions that resembles the iterative and incremental approach. This resembles as a scaled down approach of the predecessors. The key element to Agile is it ensures that the risks elements are at bay. The earlier methodologies have galvanized into the Agile and Agile would be a reflection of its predecessor’s best practices.
Kracking the Agile Monster Sprint=Requirement/s
One sprint would contain analysis, design, development, testing, and deployment. This sprint would form one delivery e.g. 1.0.1. The next sprint would be delivery 1.0.2 so on and so forth. There would be multiple such sprints across the project/product timelines scale. Meaning there would be multiple such sprints spanning the entire product life cycle from Inception phase till end of the product life span. The following diagram depicts Agile at the core.

Agile Roles
The following diagram depicts the overall governance structure for Agile projects
Stakeholders Management
Stakeholder Management is an important discipline that successful architects can use to win support from others. It helps them ensure that their projects succeed where others fail. The technique should be used during initial in the engagement to iron out the unknowns and streamline the operations management part of the engagement.
Risk Level Classifications
Impact classification Vs Risk Level for the Unknowns listed in the following sections
| Risk Level | Impact Classification |

| Medium Risk | Minor Timelines Slippages, cost and effort overrun anticipated if not taken care |
| Low Risk | Negligible Timelines Slippages, cost and effort over anticipated if not taken care |

Passing Thoughts
So how would this so called check list benefit me and my track. Generally, for the Agile Programs everything is agile in nature. The program manager, queries, the person sitting in the adjacent cubical, the dudes serving chicken curry in the B12 canteen. But a certain thing is every time there is new project requirement/s that comes to me I have a set of generic questions that would nag me till the final deliverable is handed over to the customer. This list contains few of those questions/queries/pain points. They are all legitimate in nature the key is when you may wanna apply them in real life problems or scenarios. There are specialized version of Agile that would be applicable to custom, package, legacy, web services but the core is what I have tried explaining in my artifact.
I believe the Agile, RUP and MSF are the big-boys of the Software Methodologies and we will get to hear of them more often that not in the coming quarters. RUP and MSF are specialization of Agile to a certain extent and at time things would hover above reality and beneath illusion and in which case I generalize all the lingos to the big dady – Agile Methodology. You may wanna check this check list even if your program manager is not bulling about Agile. Think about it.
