VIBE – the solution to reduce IT costs

The beauty of Vibe framework is that it can reduce IT costs as well as friction between IT and business. Let us take a typical data integration project  - for example, creating a simple report — which involves taking data from multiple source systems including mainframes, AIX and load it into forecasting tool (Oracle) for analyzing future demand. The project involves a – Business analyst who gathers requirements from business users and comes up with functional requirements specification document, Solution architect understands the functional requirements specification document and comes up with a high level design (HLD) document. The design document is fed back to business users for approval and then to Designer to create a low level design (LLD) document, designer creates LLD from HLD provided by solution architect (which serves as pseudo code) and Developer who does coding, unit and system integration testing, supports UAT and deployment. In a typical outsourcing model the business analyst and solution architect role is filled by a person sitting at onsite and designers and developers will be from offshore.

Let us say the total effort for this project is100 person days (that’s three months to get only a simple report). Out of 100 person days, 10 person days will be devoted for requirements gathering, 20 for high level design, 50 for low level design + development + unit testing, 5 for system integration testing, 10 for UAT and 5 for deployment. An addition of 30 person days will have to be devoted for change requests as there will be some changes in business requirements(like real time reporting, moving data into cloud …) during this time frame.  So, in three months, we will get something, with lots of people involved.  Let’s hope it’s what we need.

 Now let us examine the effort with the Vibe framework.  With Vibe, business analyst will be able to come up with a mapping (80% reusable code) in the Informatica analyst tool which can be directly imported to multiple platforms like Informatica’s Powercenter, hadoop or the cloud. So the effort for HLD and LLD is almost nil and development effort will be an average of 20 person days which involves importing the mapping, changing the sources and target and unit testing. All other aspects remaining the same, now with Vibe there will a 45-50% of effort savings. The effort for change request will also be less as the process is more agile and the code can be imported to multiple platforms.

Expected Effort savings with Vibe framework

Now let us look at the cost perspective. In the traditional scenario, Business analyst will be taking 20% of the total cost, 20% by the solution architect, 20% by designer and the final 40% will be developer costs. With Vibe, the role of solution architect and designer is taken care of by business analyst himself.  The developer cost is also less as the mapping is partially created. So there will be 40-50% of savings in cost (both onsite cost as well as the total cost) as well.

Expected Cost savings with Vibe framework

In a traditional scenario most of the delays and cost overruns are due to the differences in what is needed Vs. what is delivered. Business users complain that IT doesn’t understand their requirements and when you ask the IT folks, they say the requirements were not properly documented and the business “assumed” that the functionality would be delivered. This miscommunication makes the job of Business analyst very challenging and also means a head ache for the C-level executives because they can’t get the information they need when they need it. With Vibe the challenges faced by business analyst for requirements documentation is highly reduced as he or she can directly show to the business the expected output (in our case- the sample output data for forecast report). From a CEO perspective, it is a “win-win” as the friction between the business and IT almost goes away and there is significant reduction in IT expenditure. He, or she, can happily concentrate more on increasing the business growth. Thus Vibe keeps everyone happy.

Evolution: The General Store to the Individualized Shopper

The retail industry has seen a major transformation since its evolution. Tracing back to the 18th century where the concept of retail was limited to a “general store” the industry has now grown to the concept of the “individualized shopper.” Initially, the power lay with the merchants, then it was shifted to “brands” and then to “big-box chain stores.” Today the power has shifted squarely to the consumer. This new consumer is empowered – primarily through online and social channels – with nearly limitless options on their path to purchase. The industry is beginning to recognize that the experience they offer, whether in store or online, must be centered on this new consumer reality. (more…)
