Case study 3.1 Innovation at Google
Question
Explain how Google generates revenue and exploits innovation in digital technology to
identify future revenue growth. You should also consider the risk factors for future
revenue generation.
Googles revenue has traditionally been based predominantly on advertising which is divided
into these models:
Chaffey, Digital Business and E-Commerce Management, 6th edition,
Instructors Manual on the Web
Pay-per-click Sponsored links within the Google Search Results (and partner search
engines
such as AOL)
Pay-per-click and CPM model within partner sites of the content network which
Risk factors for future advertising revenue include:
Competition in bidding has traditionally driven up prices but this could fall as
companies
become more effective at optimising their investment through introducing
wastage.
Advertising revenue from the content network may fall as site owners explore other
ad
models and clickthrough rates on Google Ads fall as familiarity increases.
Questions for debate
Debate 3.1 Best-of-breed vs. single-source systems
Selecting best-of-breed applications from multiple system vendors for different digital
business applications such as enterprise resource planning, customer relationship
management, transactional e-commerce and supply chain management is a better
approach for an effective digital business infrastructure than using a single-vendor
solution.

Activity answers
Activity 3.1 Infrastructure risk assessment
Make a list of the potential technology problems faced by customers of an online retailer.
Consider problems faced by users of digital business applications which are either internal
or external to the organisation. Base your answer on problems you have experienced on a
website that can be related to network, hardware and software failures or problems with
data quality.
Some of the possible problems you may have identified are:
2. Website not available.
4. Ordered products not delivered on time.
6. Customers privacy or trust is broken through security problems such as credit cards
being
stolen or addresses sold to other companies.

Activity 3.2 Opportunities for using web services by a B2B company
Develop a balanced case for the managing director explaining the web services approach
and summarising its advantages and disadvantages.
Advantages of web-service
Readily accessible from remote locations.
Disadvantages
Performance slower due to network and shared access.
Activity 3.3 Overcoming limited use of intranets and extranets in a B2B
Company
1. A B2B company has found that after an initial surge of interest in its intranet and
extranet, usage has declined dramatically. Many of the warning signs mentioned in the
KM (2002) article listed above are evident. Suggest ways in which the digital business
manager could achieve the following aims:
1. Increase usage.
2. Produce more dynamic content.
3. Encourage more clients to order (extranet).
1. Increasing usage.
The solution is similar to marketing any product, or indeed a website. First, the digital

2. Produce more dynamic content.
The manager must check that suitable processes are in place to update static information such as
phone numbers if the intranet is not trusted it will not be used. An education programme
3. Encourage more clients to order.
Encouraging use of an extranet or intranet is similar to encouraging usage of a public facing
open website, that is, its managers:

Activity 3.4 Selecting open-source software
1. For the different alternatives facing a technical manager below, assess:
(a) Which is most popular (research figures).
(b) The benefits and disadvantages of the Microsoft solution against the alternatives.
(a) Popularity

C.
Language
(b) Benefits
Benefits could include paid support and a good quality knowledge base. However, many
bulletin boards are available for open-source software. Disadvantages of using the Microsoft
solution are the cost and the time it is likely to take to communicate the problem and have it
solved in a new release.
2. Make recommendations, with justifications, of which you would choose for a small
medium or large organisation.
A. Operating system: Microsoft/Windows XP/Vista/Server or Linux (open-source) for
server and desktop clients.
B. Browser: Internet Explorer browser or rivals such as Mozilla Firefox or Google
Chrome which is part based on open source.
C. Programming language for dynamic e-commerce applications: Microsoft.Net or
independent languages/solutions such as the LAMP combination (Linux operating
system, Apache server software plus the MySQL open source database and scripting
languages such as PHP, Perl or Python).
A. Operating system.
B. Browser.
C. Programming language.
This is more difficult to establish. PHP is used on main free web servers such as Apache, so
possibly is more popular than ASP or ASP.Net.
For small organisations, using non-Microsoft products such as OpenOffice is appealing in terms
of price. For larger organisations, the lack of paid-for support and uncertainty of future support
