Getting the Most Out of Your Investment: Three Steps to Revitalize Your Legacy System

Tuesday, October 4th, 2011

Companies don’t need to “rip and replace” large portions of their IT investments in order to gain the set of features they wantBy taking a multi-phased approach to incrementally roll in functionality, organizations can benefit from quicker ROI without the costs and risks associated with “big bang projects”. This multi-step approach is a win-win for business and IT; business can reap the benefits of go-to-market features sooner and IT will be able to adapt to changes more quickly.  Here is our recommended three step approach to revitalizing your IT architecture:

  1. Leverage What You Can: Revitalization efforts have to be carried out with a focus on leveraging your existing architecture. Wrapping your existing assets in web services keeps some of the older technologies in play.
  2. Implement As Needed: Keep it simple and only add functionality that’s really needed. By purchasing pre-built components that augment your existing systems, you can add the functionality you want with minimum configuration and customization.
  3. Rapidly Build New Functionality: Once you’ve decided on the new functionality that you would like to add to your system, we recommend that you rapidly develop these applications using software development automation frameworks such as FAST 8x. By rapidly building SOA-compliant components, you can leverage modern technologies and get the benefits of development efficiency.

Once you have implemented all three steps, you are on your way to fulfilling immediate business needs while achieving long term architectural goals for the future.

Darwinism of Innovation: The Evolution of Automation and the Software Development Industry

Wednesday, August 24th, 2011

In 50 years, will we still have armies of programmers coding business systems for companies? Will it still be necessary?

In the history of industrial growth, the replacement of tedious production processes with automation is essential to the progression of invention and ingenuity. But we seem to have forgotten this key to innovation in software development. We are so caught up in creating new processes, new languages, new “big system” solutions to address the same old problems of tedious code-writing in traditional software development that we forget the true purpose of this industry in the first place – to replace tedium and inefficiencies of the paper-pushing era. We seem to have it stuck in our heads that software development is too complicated to automate.

The key to replacing expensive, labor-intensive and entrenched systems is not by engaging in expensive, labor-intensive big-bang projects, but in increasing productivity, flexibility, and function-leveraging. This is industrial Darwinism at its finest: instead of replacing one inefficient system with another, find a solution that eradicates the costliest, labor-intensive processes altogether. In short, creating dynamic software that will automate technical coding so that the user can focus on the functionality and conceptual use of the software is the true innovative key to the future of the software development industry.

Here at FAST, we have done just that. As a part of a four-person newly hired team of university graduates, we were assigned the daunting task of creating a fully functional application with FAST 8x in just four days, inclusive of training, configuration, building, and presentation. The exercise focused on showcasing how software development automation can achieve what normally would take a team of developers, analysts, and engineers months of code-writing to accomplish. None of us had any previous experience with software development; only one of us had any true technical knowledge of software design, and we were granted access to one engineer to assist us in the configuration process. By the end of the week, we had presented a production ready SOA based set of components that included 40+ database tables, 4 components, full user interface w/20+ business processes, 100+ web services, integration into other applications, 5,000+ test scripts (that are on a nightly regression cycle), technical documentation, and a how-to guide.

This proof-of-concept exercise is a reflection of what we’ve been doing for months on a larger scale with our life insurance client. In less than nine months, we were able to build an entire suite of legacy-replacing components which included 800 database tables, 35 components, full user interface w/25+ business processes, 700+ web services, integration into other applications, 13,000+ test scripts, technical documentation, and a how-to guide. This legacy system modernization process, which would have normally taken approximately three to five years to develop traditionally, is a remarkable step towards the breakthrough technology necessary to take software development to the next level.

20 Questions to Understand What Your Vendor Means by “Re-Architect”

Friday, July 29th, 2011

I think the term “re-architect” needs to be stricken from our vocabulary.

Whether you’re building a home or a system, the architecture is the first thing you decide upon.  It’s fundamental.  Just as the architecture for a home lays out the blue print for the physical structure, the architecture of a system lays out the blue print from which components and functionality are developed. Before the first batch of concrete is poured or the first line of code is written, you put that blue print in place, and from it every piece of the home or system is defined and developed.

With large-scale systems like policy administration, every line of code is written with that architecture in mind and it is core to everything in the system.  The architecture defines the very essence of the system – it is beyond “foundational”.  Once you go down an architectural path, you might be able to make changes to it, but there’s no re-doing the architecture unless you throw everything out and start from scratch.

So when vendors throw around the term “re-architect”, I think it can be very misleading.  “Re-architect” seems to imply that they have applied some fundamental, structural changes to the software without compromising the system itself; yet, to truly “re-architect” anything would mean a complete overhaul of the architecture that defines it. So, it’s kind of a misnomer.  If they had actually rewritten the system, they would say “we did a complete 100% rewrite from the ground up”.  If they didn’t rewrite it, then there is NO WAY the system is not compromised by the legacy architecture it had.  When you’re purchasing a system – large or small –, there’s a fair amount of legacy architecture and legacy code that comes with the package in almost every case.  You may be OK with that, but you need to have a good appreciation for the extent of it.

Along the lines of finding the “freshness date” or newness of the architecture of the system – as well as just doing some good due diligence – here are 20 key questions I think you need to be asking your vendor as part of the assessment:

  1. When was the last time you “re-architected”?  What parts were not rewritten and why?
  2. Why was the “re-architecting” deemed necessary? And what was the overall impact to the system in terms of % of code rewritten?
  3. What year was the oldest code in your system written?  (I suggest you have the vendor make that a contractual representation and you should get an honest answer.)
  4. For your policy administration system, do you have a monolithic or component based object structure within your code?  If component, do your components reference each other within the code?  Are there database joins that go across your components?
  5. Can you tell me how many lines of code your software is (by language)?  (The purpose here is to gain an understanding of the ratio of newer code to legacy or older code.)
  6. How many customers have converted or committed to converting to this new architecture? For those who have converted, what was the average project duration?
  7. How many lines of code did you write for each of your last three new client implementations?  How long did those implementations take?  (Make sure you can reconcile the lines of code to the duration and that it passes the “smell” test – in other words “if there’s that little code, why did it take so long?”)
  8. Assuming coding changes are required (and they will be), what restrictions are there on using external consultants?   Here the vendor will likely represent that you don’t need to make changes to the core system – do not under any circumstances accept that answer.
  9. How many developers do you have supporting clients offshore and onshore on this platform today?  (Given the low amount of programming you will be told is required, make sure you can reconcile this answer to the answer in #7.)
  10. Am I forced to use your proprietary rules engine?  How easy is it to swap out?
  11. What contractual guarantees are you willing to make about maintaining this platform in the future and future releases?
  12. What is the biggest implementation (# of policies) that anyone who is running on one of your past two releases of the platform we are buying?  (Work to make sure that the answer IS for the platform you are buying.)
  13. List your current clients for the platform I am buying and version of the platform they are running.   (Accept that some clients can’t be named, but insist on a complete list.)  Exactly what functionality are they using and what is the product mix?
  14. Can I have the attendee list from your last user group meeting?  This IS NOT highly confidential and they should be able to give it to you.
  15. Who was the last policy admin customer to go into production for individual life?  Individual annuity?  What were the released version those companies used?
  16. How long did it take your last policy admin customer to go into production (from initial requirements through production)?
  17. Over the past five years, how many companies who have selected your platform where you started projects and the customer never ended up going into production?  (This is information you can learn for yourself in the industry.)
  18. How many policy administration customers do you have that haven’t made a significant number of code changes for customization?  Please name them.
  19. How many policy administration customers have done production upgrades to a newer version over the past five years?
  20. How many customers have terminated maintenance agreement in the past three years?
