Assignment:
Review a selection of your colleagues' posts from earlier in the
week, focusing on the best practices and key activities that are
necessary in successfully managing business information
systems. Respond to two or more of your colleagues in one or
more of the following ways:
· Explain the similarities and/or differences between your own
findings and those identified by your colleague. Why do you
think your analysis of the case was similar to or different from
your colleague's?
· Share what you believe could potentially impede or enable an
organization when aligning its IT and business strategy.
· Offer additional best practices or tools organizations could use
in aligning IT strategy and business strategy. Explain why those
are important and effective. What specific steps does an
organization need to take to make sure it continuously monitors
how well these strategies align?
Please be specific, and use citations and references as
appropriate and necessary.
1st Colleague to respond to:
From my analysis and interpretation, it seems to me that there
are currently lines between business and information technology
to the point that the respective departments have very little
structures of communication or project planning. Cheryl Smith
needs to respectively show these managers an example of a

10. previous high priority project and how the lack the transparency
affected its delivery to the consumers without alienating the
group. She can then utilize a comparative model to show how
the reorganization of the department with a clear direction and
focus will allow predictive feature development and business
value quicker. Additionally, I would advise utilizing some
liberating structures (there are several to choose from) to get
inputs from the managers so that they feel like their ideas are
being heard and their concerns are being addressed.
Within my current organization that I work for, I have been
fortunate that they have promoted Agility to the teams and
continue to evaluate the organizational structure to ensure
critical business areas have dedicated IT resources.
Prioritization of features, constant feedback, iterative deliveries
that can be measured, and partnering our business with our IT
teams have been vital to building new functionality and staying
ahead in technology adoption in the marketplace. Infrastructure
is another area outlined by Munro and Khan (2017), "A common
operations team with common skills to support a common
infrastructure is highly cost-effective. This allowed the
business-facing IT groups to be totally responsive to business
needs and priorities but ensured that all applications and
systems came into and were supported by a common
infrastructure." (p.7) This has been a crucial facet of our
operating model as well. We look for additional ways to take
this to another level within IT; we empower our teams with self-
service capabilities to spin up additional environments and
databases by appropriating automation.
A couple of strategies from researching materials available to us
via the Walden Library were to utilize a scorecard or similar
mechanism to evaluate how much an IT investment is currently
costing the company in contrast to the department's contribution
towards the highest priority business value. (Karin, 1998) There
needs to be a clear vision across both business and IT that is
understood and aligned to drive the organization towards higher
goals. As written by Bruce Karin (1998), "innovations have

11. been successful because they increased their flexibility to
reconfigure markets, customers, and products, while
simultaneously increasing convenience and information
availability to the end customer" (p.2). Flexibility, alignment,
and transparency seem like simple terms that are used loosely at
times by companies. Still, without them, we risk building the
wrong things and losing strength within the marketplace. When
Cheryl Smith reviewed the current skills and number of IT
employees, it was found that WestJet was at a proper level to
support the business but not adequately focused on business
priorities or directed to different business objectives. IT
staffing levels, department investment, skillsets within those
employees, and resource dedication are items that leadership in
any size company needs to review and adapt when needed
continuously.
In closing, there are several risks to an organization that doesn’t
continue to adapt IT investments in response to the business
strategy needs. In my professional experiences, you will have a
laundry list of business projects from numerous different areas,
all trying to get the resources they need at the same time. In the
end, you reduce the effectiveness of your IT staff and increase
timeline delivery on potential improvements that could
positively impact consumers. Over time, this continues to
“snowball” as the company falls further behind from the
competition within the same market space. Those willing to
adapt to change and stay ahead of the technology curve will
have the best opportunity to continue growing.

12. 2nd Colleague to respond to:
Organizations need to understand the role of information
technology in corporate strategy because it fosters innovation
and growth which drives success. In this case study Cheryl
Smith, the CIO of WestJet understands the influence of
information technology and the importance it has on revenue-
generating operations for the company. Her internal assessment
along with the help of a third-party analysis has helped to
identify gaps. Cheryl Smith's first instinct was to bring two
performance experts to carry out a benchmarking study with
similar companies in the transportation industry. The objective
of this study was to compare WestJet’s IT cost, resources, and
budget to the industry standards. From the results of this study,
Cheryl was able to find out many facts including that the IT
group of the company was technically competent. She realized
that comparing to the industry the IT number of employees had
different skill sets. Another fact was that half of the systems,
operations, and procedures of the company were industry-
standard. The IT department had invented its operation around
the company’s needs. The study showed that IT was on target
with the industry with its budget and number of employees.
Lastly, the IT department was structured according to what
suited it better. It had been using its internal functions for
planning, operating, building, etc. The work structure allowed
everyone in each group to perform activities with other
members enabling them to respond quickly to emergency
requests. Cheryl was able to break everything down and find the
strengths and weaknesses of this strategy.
My organization is continuously looking for numerous ways to
find the right technology, expertise, efficient processes and
procedures, and solid systems. Any company or corporation
cannot survive without an IT Department run by an IT officer or
a CIO. WestJet did not have a CIO in its IT Department, and
this was a problem for them. The IT Department could not keep
up with new developments in the market, and other challenges.

13. In my organization, it is competent that there is an officer for
every department. When there is an error with the computer
software there is always a number to call and the IT department
handles it. The CFO understands that when you do not hire
someone with expertise to solve these issues it affects the
company as a whole. When the system is slow or not working it
hinders the process of teller transactions not going through. My
organization's business strategies are that any small internal
error can create a greater issue if not fixed.
The best tools and techniques that organizations can use to align
IT strategy with business strategy is strong communication,
collaboration, and care. According to Balakrishnan (2012),
“This seems like an obvious one, but most CIOs underestimate
the amount of the communication and how one-sided it can be”
(Leadership). Communication is key. It is crucial to talk to
businesspeople in a language that they understand. The IT
department must translate and consolidate requirements into a
cohesive plan. Both parties need to hear each other out and take
in interest in what they are speaking about. Not being able to
understand each other’s viewpoints can create misalignments. It
is better to plan ahead and accordingly. This creates credibility
and engagement. Collaboration is working with groups of
people to better diagnose a problem. This technique helps clean
up the issue at a faster rate because you are working with many
people. Understanding and asking questions in this team effort
will be helpful. This part of the process can include achieving
business goals, improving customer service, business
relationships, lower IT costs, improving risk management, and
organizational effectiveness. When they gather data it will give
them a comparison to where they share similar interests with
their competitor. Genuinely caring about a company’s business
is what aligns everything together. If there is no interest and no
passion then you are just doing it for the wrong reasons. When
you genuinely care your idea becomes more effective and
businesses value your thoughts and reasoning. Understanding

14. people on their level and helping them not only brings lights to
their eyes but gives you insights on what more you can do to
achieve your results. An alternative organization use to ensure
their strategies are in alignment is that they innovate and
recognize and reward those who adopt new behaviors.
Innovation helps bring in change. Change can be acquired
through different resources. It takes one person to jump ship
before everyone else does.
The WestJet must adopt these resources for it to still operate.
Not using these resources comes with many risks and can create
a catastrophe. WestJet would not operate smoothly. This
decision would affect all of the departments and employees.
There would be no communication between the IT department
and other business units. The connection would be lost and
there would be a loss of competitive advantage. Many customers
will join the rival firm. With its budgeting and planning risk,
there would be not enough funding to allocate funds in its
correct plan. Projects would not be completed which creates
unproductivity, and everyone will end up quitting out of
frustration. Eventually, all of the operations would cease due to
this horrific play. Not looking for the alignment gaps can bring
the alignment of IT and business strategy to a halt. Investing in
these resources would be a better choice if employees would
like to see this Airline operate. According to Munro and Khan
(2013), “As Smith and the senior IT leadership team pondered
the “big picture” in these opening weeks, they concluded that if
WestJet hoped to sustain its rate of growth and build on its
remarkable success, IT would be a critical success factor” (p. 7)
