https://www.forbes.com/sites/chunkamui/2012/01/18/how-kodak-failed/
Summary:
The resource is about the strategic failure of Kodak to adapt to the technology lead to the
downfall of the company. This was the cause of the Kodak decade long decline to the digital
photography which destroyed on their business model. In this resource it highlights how the
management of Kodak was unable to see the digital photography as the disruptive technology, and they
failed in adapting to the established business model with the use of the digital photography which had
potential capability.
I have chosen this resource to provide an insight on the importance of adapting
to changes in new innovation especially to the disruptive technology. The
organization should adapt to the changes in technology especially in this era where
there has been revolution of the technology in every sector.
The main key ideas of the resource is about how the new technology
(disruptive) can impact an organization either positively or negatively. Kodak
organization failed in taking decisive action to be able to combat on the challenges in
the business through adapting to the digital photograph technology. The organization
did little in preparing for the later disruption. They did not prioritize their problem
towards turning them to opportunities for the advancement of the technology rather
than the founder George Eastman, investing in color film rather than the digital
photography.
This resource is useful since it offers some insights on the use of poor
strategies particularly in the digital era might impact on the business in negative way.
The organization lack of adapting to this new technology lead to its long decline

15
downfall.

Title and Reference: Myki ticketing system failure
Alex. W., and Matt. J., 2015. Myki ticketing system failure revealed in leaked business case. Accessed
At: http://www.heraldsun.com.au/news/victoria/myki-ticketing-system-failures-revealed-in-leaked-
business-case/news-story/b114ea522aa55a4fe8f39190690bb557
Summary:
The resource is about Myki project which involved the Victorian transport Ticketing
Authority which they intended to replace the Melbourne existing ticketing system with the use off the
smartcard system that would enable the passengers to touch on and off to all the trams, trains as well as
in the buses through the transport grid in Metropolitan. The project was a failure as it suffered various
issues from initial beginning since the assembled TTA members they lacked sufficient skills when it
came to dealing with the important ICT project as they lacked detailed knowledge of the transport
ticketing environment.
I have chosen this resource since it provide insights as to why the complex big
ICT project fail. In this case the failure was because of lack of the TTA members
lacked skills to deal with the project. There was also the issue of unnecessary
complexities of the contract as the TTA as well as the selected vendor negotiated on
the outcomes that entailed on the documentation exchanged between the parties via al
the process of tendering.
The major key point on this resource is it offers some insight on why major
ICT project fails such as this case of Myki system which failed and it cost significant
amount of money which was above the previous projected cost.
This resource article highlights how the big and complex ICT project such as

16
Myki failed as a result of lack of expertise of TTA members in dealing with major
project. From the resource I have learnt that any slight failure of a single component
of a major project could lead to the entire failure or delay in the project completion.
