Productized Services - Definition





Software failure is, for the mostpart, predictable and avoidable.Unfortunately, most organizationsdon't see preventing failure as anurgent matter, even though thatview risks harming and maybe evendestroying the organization.

Understanding why this attitudepersists is not just an academicexercise; it has tremendousimplications for business andsociety.

Software failure





Enterprise System Life cycle cost





Software is a vital component of anycomputer system and allows usersto perform tasks such as wordprocessing, database managementand Internet browsing.The pricing structure of softwareranges from free applications such

as web browsers to expensivecustom programming solutions for corporations.

What Factors Affect Computer SoftwarePrices?





Computer software prices arebased on a number of factors,including the intendedconsumer, development costs,licensing fees, age of theproduct and an economicdetermination of what price

point will maximize revenues.

Software is divided into two primarymarkets, home and enterprise.Home consumers generally spendtheir own money and buy software for fun or to make their lives easier.Software companies often producecheaper versions of their products

with fewer features for the home user.





Enterprise-level consumersusually need robust, full-featured packages for their businesses and often pay lessper unit by purchasing manysoftware licenses at a time. Inthe academic market, studentsand educators often can buydiscounted software for schooluse.





Most IT professionalsknow that project failureis a common andserious problem inorganizations of allkinds. New researchattempts to quantify theextent of IT failure in theworldwide economy.

Worldwide cost of IT failure: $6.2 trillion




Most IT failure researchseeks to determine thepercentage of projectsthat run over-budget,are late, or do notdeliver expectedresults. While thosenumbers are important,they do not convey aconcrete sense of theoverall cost impact

created by failed IT.

Worldwide cost of IT failure: $6.2 trillion




According to the World Technology and Services Alliance, countries spend, on average, 6.4% of the Gross Domestic Product (GDP) onInformation Communications Technology, with43% of this spent on hardware, software, andservices. The other 57% is spent oncommunications technology. This means that, onaverage, 6.4 X .43 = 2.75 % of GDP is spent onhardware, software, and services. I will lumphardware, software, and services together under the banner of IT.

Worldwide cost of IT failure




According to the 2009 U.S.Budget [02], 66% of all Federal ITdollars are invested in projectsthat are "at risk". I assume thisnumber is representative of therest of the world.

A large number of these will

eventually fail. Assume the failurerate of an "at risk" project isbetween 50% and 80%. For thisanalysis, I'll use the average:

65%.

Generation Role of Vendors (1 st ) Insourcing Provide tools(2 nd ) Outsourcing Provide testing(which subsumes the

tools)(3 rd) Testsourcing Provide test artifacts(which subsumes

the testers, testing and tools)

Generations of testing




Insourcing :-

In the beginning, very littletesting was outsourced. Testingwas performed by insourcers ,

people employed within thesame organization that wrotethe software. Developers andtesters (often the same peopleperforming both tasks) worked

side by side to get the softwarewritten, tested and out the door.The vendors’ role in theinsourcing days was to providetools that supported this self

service testing.

Outsourcing :-

The vendors’ role soon changed asdemand for more than just toolssurfaced. Instead of just providingtools to insourcers, vendors emergedthat provided testing itself. We callthis outsourcing and it is still thebasic model for the way many

development shops approachtesting: hire it out.

Productized Services - Definition

Rethinking IT services in a new World - The Service Productization Approach- By Sindhu B, Practice Manager - Telecom VAS, CTO Office



It is defined as an offering with a set of repeatable activities anddeliverables

Productization of services can be mostly accomplished byassociating tangible features with intangible service offerings. These

tangible features could be in the form of personnel, collateral,methodologies, pricing, facilities, or other attributes. By associatingtangible features with intangible services, we can build clientconfidence during the sales cycle as well as during the servicedelivery phase.

Productized Services : Definition - 2



Allow the market to self-service their final deliverables bymeans of standardized packages with key parametersand KPIs, which dramatically shortens sales cycles andreduces cost of sales.

Help in ensuring repeatability and consistency, and alsoreduce the amount of customer intervention in theprocess, which in turn improves profitability.

Allow service providers to achieve efficiencies asdeliverables are pre-defined, and enable them to offer differentiated and top-up services at a premium, therebyincreasing profitability.
