Architecting software in a new world

I came across an interesting O’Reilly web cast titled ‘O’Reilly Webcast: 10 Things Every Software Architect Should Know’. It is important ‘words of wisdom’ definitely for software architect

But, well, I believe much of it is quite relevant to many others as well, It is all the more so as software has become integral part of our every day life and software development is getting to be increasingly, as Grady Booch points out

The 4+1 views of game development

This title is inspired by an IEEE paper 4+1 view model of software architecture.

The referred paper on software architecture suggests five views to organize description of software architecture. This helps to separation of concerns, with each view addressing concerns of a specific stakeholder role like programmer, designer, integrator, and system engineer with usage scenarios being central to all.

Similar approach helps to understand and manage game development. Note that I am referring to game development; not necessarily game architecture. It helps to look at game development from various perspective with gamer perspective being central to all.

The 4+1 views of game development

These are not necessarily orthogonal; rather elements of one view are connected to elements of another just as in case of 4+1 view of software architecture. Each view helps define focus on specific stakeholder concerns, and in turn, roles, skill sets.

Presenting success at RSDC 2009

It feels great to selected to presented at IBM Rational Software Development Conference 2009. Unfortunately, due to personal priorities, I would not be able to make it to the conference.

Success (QM15: Effective Test Automation of SAP Implementations) would be presented by my manager Vipin Kumar (Managing Director and Software Engineering Evangelist, Astra Infotech Pvt Ltd), who has played a crucial role all through for the success of this project

What’s your opinion? Which is best? RUP, Scrum, or XP?

Following are my comments on “What’s your opinion? Which is best? RUP, Scrum, or XP?” in Agile Alliance group in Linkedin

First comment:
Why not RUP and …? RUP is a process framework/knowledge base and not a prescriptive process. You rather use RUP to derive a process instance

Subsequent comment:
Great to see the active and healthy discussion and hope to see this progressing further.

In this context, I would like to reiterate and substantiate my statement that RUP is not a process but rather a knowledge base and process framework. Lists of activities, relative order in which they should be performed, which artifacts to create, and dependency between them are more of guidelines/reference, and not meant to be prescriptions. Interesting links to read in this line would be: http://www.agilealliance.org/system/article/file/941/file.pdf and http://www.ibm.com/developerworks/rational/library/content/RationalEdge/jan03/StoryOfRUPManager_TheRationalEdge_Jan2003.pdf . There are many more but I hope these links clarifies

One does not adopt knowledge base and process framework. Rather, you pick and choose from it. I agree, “extract any element of RUP you think you need on a given project and add it to Scrum”, as pointed out by Richard, is the right way to use it. Meaning, in that case you are using RUP as a reference, and not as a textbook or bible. Again, you need not worry about size of encyclopedia if you know what you need from that

Again, I believe, good architecture and design is important for software development and role of architect, for me, is in war front (and therefor, hands on and continuous; again in sync with RUP), and not in the control room. Such architecturally-orientation is not in conflict with agile practices. In my understanding, what agile practices stand for is ‘right sized” architecture or design, rather than discounting their value.

Incidentally, I do not ask my customers to adopt RUP but I present to them as a knowledge base only. I also use it as a knowledge base, at the back of my mind, in my consulting service.

I would like to hear from you on your thoughts and on what you find in as conflicting

An old farewell note!

Rational Software Corporation was a company that I longed for, worked a couple of years there and still cherish my days there.

Going through my old records, I picked up my farewell note to Rational. It reads as below:

Farewell to ‘Rational’

Firm stands ‘today’, the moment of truth
Basking in the glory of the yesterday
Lo ! beckons the future, excitements set forth
It is time for me to move on, I say !

Shall stay with me, for ever and ever
Some ‘Rational’ thoughts, so fresh as ever
The joy of sharing, and caring for another
The fun of learning, and working together

It hurts to say ‘bye’, dear ‘Rational’
Oh! my friends, it pains to bid ‘farewell’
We shall meet again in the world, so small
We shall hold together, with a heart no small

Let me be gone now, for a while
To join our hands again, in a little while
For some purpose, quite worthwhile
To help our customers, with a sweet smile

I set forth to achieve certain tasks back in 2002, and on retrospection, I am glad to have

Authored a few successes that I had set my eyes on:
1. Case studies of success in India
2. Case study of success in Germany
3. A good customer base
4. Customer testimonies

And been part of a few others that I dreamt of:
1. Astra Model Creator
2. Astra Test Automat

Software Factory, MDA, Astra Model Creator, and Astra Test Automat

Often Software Factory and Model Driven Architecture as two orthogonal approaches.

For me, both are two different perspectives of software product engineering. Abstract and concrete modeling and transformation, and production at a software factory as dictated by production process dictated by architecture go hand-in-hand to make a successful product line

We, at Astra Infotech, enable the merge with our Ready for IBM Rational Software Astra Model Creator and Astra Test Automat

Yet another proud moment!

A great day indeed!

Astra Infotech‘s Astra Test Automat is awarded the prestigious ‘Ready for Rational Software’ certification from IBM, with best practices compliance.

This is now Astra Infotech‘s second solution after Astra Model Creator to receive this certification

Astra Model Creator is now ‘Ready for Rational Software’

Development of quality software requires a rigorous software architecting and design effort, and development strictly controlled by defined architecture and design. Astra Infotech‘s solution Astra Model Creator supporting model driven development is now ‘Ready for Rational Software’
