risk in a systems analysis and design project, and how does a project manager cope with risk during the stages of project management?
The major sources of risk in a systems analysis and design project at a strategic level include environmental, external and design risks and over t ime these can accelerate and change the entire nature of a given project plan and direction. These three strategic risks often lead engineering services, project management, organizational and legal risks as well (Fu, Li, Chen, 2012). The strategic elements of customer, technical and delivery risk also serve to further constrain and many times clarify the systems analysis and design foundation of a project (Fu, Li, Chen, 2012). Constraints force trade-offs which in turn lead a project to gain greater clarity of vision and greater acuity of focus on desired results (Fu, Li, Chen, 2012). A project manager will often cope with sources of…...

Alcan IT Management Systems Analysis
Alcan's growth as a global conglomerate in the aluminum and metal fabrication industry follows a similar trajectory of many companies whose business models forced rapid, highly distributed business models at the expense Information Technologies (IT) management systems consistency and performance. Alcan's IT management systems and underlying infrastructure have become balkanized as the company has grown into four separately functioning and highly autonomous business units. In evaluating the key success factors of successful Enterprise esource Planning (EP) implementations in multisite locations, the most critical factor overall is creating a unified, well synchronized system of record across all EP instances (Hanafizadeh, Gholami, Dadbin, Standage, 2010). A second key success factor for multisite EP implementations is the ability to negotiate a very low level of maintenance pricing with EP vendors in the form of multisite or use-based pricing instead of the traditional per-seat model (Law, Chen, Wu, 2010).

What are the advantages and disadvantages of these system installation methods?

Q1.Direct installation "cold turkey"

Direct installation 'cold turkey' is when the old system is completely shut down before the new system is turned on (What is implementation, 2001). The main disadvantage of this approach is obvious -- any unexpected 'glitches' in the new system will mean that work will be at a standstill until the new system is fixed, and there is no other alternative. This should only be used when the old system is so problematic and complicated that it is not worth continuing to run it as the new system is implemented -- or if the new system is well-tested and its ability to operate is assured.

Q2.Parallel installation (old system runs with the new)

Parallel installation occurs when the old system is allowed to run while the new system is introduced (What is implementation, 2001). The…...

Cloud Computing Changes Systems Analysis and Design
Instiution/University affiliation

Both information systems and information technology infrastructure have been incorporated into business procedures for at least two decades. In the initial development of information technology, organizations which greatly invested in information technology infrastructure achieved strong growth in market shares and returns. Given that IT is now the core of businesses, nearly all organizations own their own IT infrastructures to manage their daily business activities. In case of malfunctions in the information systems, the regular business proceedings shall be really interrupted. Though the majority of companies are not IT companies, they have to invest a great share in IT so as to run their business operations smoothly (Chou & Chou, 2011).

Information technology has turned into a necessary infrastructure which organizations need to have; however, it does not essentially offer strategic benefits for business. According to Carr (2003), the growth of the power and…...

Family Systems Theory and Farewell to Manzanar
Family roles

According to Bowen Family Systems Theory, all family members engage in role-playing beyond those of the conventional roles of 'daughter,' 'husband,' 'son,' and 'father' in relation to one another. Much like characters in a play, family members have other, unstated roles which they develop as the result of 'triangulation' or relationships with other family members. Frequently, these roles are dysfunctional. At the beginning of Farewell to Manzanar, the father of the Wakatsuki clan, Ko Wakatsuki, plays the role of a traditional, patriarchal authority. He attempts to recreate the dynamic that he regards as 'correct,' with the father's will dominating over that of his wife and children. His daughter Jeanne idolizes him.

However, after the bombing of Pearl Harbor, the family is relocated to a Japanese detention center where they must live in a collective environment with other Japanese-Americans who are being forcibly confined because…...

System Design: Oahu Base Area Network
The aim of this paper is to examine and discuss the Navy's decision to build the largest local area network (LAN) connecting the U.S. Pacific Fleet using information-gathering techniques and design methods. The system has the capacity to connect sailors and marines within the 102-million square miles of the Pacific Fleet's command coverage. Moreover it will provide the indispensable access for supplying and training the U.S. Navy. The Oahu Base Area Network (OBAN) will be the largest LAN in the world when all the phases are complete. It was started way back in 1998. It is the supporting network for the six naval commands in the Pearl Harbor, Hawaii area. Phase one has been completed. Other phases have begun in San Diego, the Pacific Northwest and the Pacific Far East, following the original business model (Kaylor, 2000). The uniqueness of this system is in its…...

System Implementation - Oahu ase Area Network
System Implementation: Oahu ase Area Network

The wireless local area network (WLAN) in the Oahu ase Area Network is made up of several different subsystems. The inputs to the system will be desktop computers, laptop computers, and embedded systems (fixed and mobile). Each client has a wireless network card that can communicate with an access point (AP). The AP manages WLAN traffic and physically connects the wireless system to the wired local area network (LAN). The wired LAN will then send the requested information back to the access points, which will relay it to the appropriate client (Conover, 2000).

The system has three modes of operation:

Op-Mode: This is the standard operating mode for system operation. The mode consists of interaction between clients and one or more server. The clients are wireless devices such as laptops, desktops and tele-robtics platforms. Servers are access points that connect the…...

However, in the most recent theory of evolution which discusses the living world appears as the result of chance and an output of different randomly selected natural mills. This kind of development came to present as a result of the need of more subjects or topics in areas such as cybernetic, general system theory, information theory, theories of games which is needed in most decision making process in line with real applications. In mathematics techniques however, there are a number of general assumption which are insufficient and most of the time very contradict themselves (Laszlo & Krippner, 1982).
Again, Laszlo (1982) outlined that von Bertalanffy considered the idea of organization to be involved at various stages in the expression of natural system. This could be highlighted from his first statement on the system which he made between the years 1925-1926, during the time when similar thinking of organism was being…...

Its business alliances have succeeded because of the past encounter and uncompromising principles of Starbucks. When Starbucks created a licensing contract with Kraft Foods, Inc., it permitted Kraft Foods to begin to make Starbucks' items available in grocery markets, and now because of that attempt their items are available all over Northern U.S. And even the United Kingdom. If Starbucks did not have the primary features of what it is looking for in an alliance, it might not have been as effective in its collaboration with Kraft Foods or any other partner. Starbucks was willing to think about the good and bad in the possible collaboration and choose on whether or not the collaboration would benefit its organization (Davidson & Fielden, 2013).

Attacks on the system security include password theft, back doors and bugs, social engineering, protocol failures, authentication failures, Denial of Service attacks, active attacks, botnets, exponential attacks including worms and viruses, and information leakage. (Fortify Software Inc., 2008); (Fortify Software, n. d.)
Servers are targets of security attacks due to the fact that servers contain valuable data and services. For instance, if a server contains personal information about employees, it can become a target for stealing identities. All types of servers, which include file, database, web, email and infrastructure management servers are vulnerable to security attacks with the threat coming from both external as well as internal sources.

Some of the server problems that can jeopardize its security include: (i) Weakly encrypted or unencrypted information, especially of a sensitive nature, can be intercepted for malicious use while being transmitted from server to client. (ii) Software bugs present in the server Operating…...

Bayesian Machine Learning for Dynamical Systems Analysis
Bayesian machine learning offers powerful tools for enhancing the understanding of dynamical systems, which are mathematical models that describe how systems change over time. By incorporating prior knowledge and uncertainty quantification into the modeling process, Bayesian machine learning can provide valuable insights into complex dynamical phenomena.
Incorporating Prior Knowledge
Dynamical systems often exhibit complex behaviors that can be difficult to capture with traditional machine learning methods. Bayesian machine learning allows for the incorporation of prior knowledge about the system, such as physical constraints or expert intuitions. This prior information can guide the learning process, resulting in....
