An unsolved problem in the field of IT strategic management that could be addressed by additional research is the lack of effective alignment between IT strategy and overall organizational strategy. Organizations across industries are heavily reliant on IT systems and technology to drive their business operations and support their strategic objectives. However, there is often a significant gap between the IT strategy and the broader organizational strategy, which can result in a range of negative effects for stakeholders.

One of the negative effects of this misalignment is the wasted resources and missed opportunities. When the IT strategy is not aligned with the organizational strategy, resources such as time, money, and manpower can be invested in IT initiatives that do not contribute to the overall goals of the organization. This can lead to inefficient use of resources and missed opportunities to leverage technology for competitive advantage. For example, a company may invest in developing an advanced analytics system without properly considering its relevance to the organization’s core business objectives, resulting in wasted resources and limited benefits.

Another negative effect is the lack of IT-enabled innovation. Technology has the potential to drive innovation and create new opportunities for organizations. However, when the IT strategy is not aligned with the organizational strategy, there is a risk of missed opportunities for IT-enabled innovation. For instance, a company may fail to explore emerging technologies and their potential applications due to the lack of alignment between the IT and organizational strategies. This can hinder the organization’s ability to stay competitive and adapt to changing market dynamics.

Additionally, the lack of alignment between IT strategy and organizational strategy can lead to poor decision-making. IT investments and initiatives should be guided by the organization’s overall goals and objectives. Without alignment, decision-making in IT strategic management may be based on personal preferences, individual departmental goals, or short-term thinking, rather than a holistic view of the organization’s strategic direction. This can result in suboptimal or even detrimental IT decisions that do not align with the long-term goals and needs of the organization.

In conclusion, the lack of effective alignment between IT strategy and overall organizational strategy is an unsolved problem in the field of IT strategic management. This problem can lead to wasted resources, missed opportunities for IT-enabled innovation, and poor decision-making in IT investments and initiatives. Further research is needed to identify the underlying causes of this problem and develop strategies and frameworks to improve the alignment between IT strategy and organizational strategy.

The given information appears to be a financial statement for a bakery business for the years 2014-2017. The statement includes various values such as revenue, costs, expenses, and interest rates. In this analysis, we will calculate and interpret key financial metrics to gain insights into the bakery’s performance and financial condition.

One important measure to consider is the net income after taxes. It indicates the profitability of the business and measures the amount of money the business has earned after tax obligations. The net income after taxes can be calculated by subtracting the income tax expense from the income before taxes. By examining the trends in net income over the four-year period, we can evaluate the bakery’s profitability and determine if it has improved or declined over time.

Another crucial aspect to assess is the end-of-year cash on hand. This reflects the amount of cash available to the bakery at the end of each year. It is calculated by subtracting the debt owed from the cash on hand at the beginning of the year and adding the net income after taxes. By analyzing the changes in the end-of-year cash on hand, we can evaluate the bakery’s ability to generate sufficient cash flow and manage its financial obligations.

Additionally, it is important to consider the average number of items sold per day, such as doughnuts, cups of coffee, and muffins. These values represent the bakery’s sales and revenue-generating potential. By examining the average number of items sold per day, we can assess the bakery’s performance in terms of customer demand and determine if there have been any significant changes in sales volume over the years.

Furthermore, the income and cash flow statements provide an overview of the bakery’s financial performance. The revenue section includes the yearly revenue generated from doughnuts, coffee, and muffins. The costs section includes expenses related to the production and sale of these items, including the costs of ingredients, salaries, and administrative expenses. By analyzing the income and cash flow statements, we can determine the profitability and financial health of the bakery.

In summary, this analysis will focus on key financial metrics such as net income after taxes, end-of-year cash on hand, average number of items sold per day, and the income and cash flow statements. By examining these metrics, we can gain insights into the bakery’s profitability, financial condition, and sales performance over the years.

Title: Exploring the Effectiveness of Encryption in Data Protection

Introduction:
With the increasing reliance on digital systems to store and transmit sensitive information, the need for adequate data protection measures has become paramount. Encryption is one such method that can safeguard data at rest, in motion, and in use. This essay aims to discuss the use of encryption in protecting data in each of these three states, highlighting its significance in ensuring data confidentiality and integrity.

Paragraph 1 – Data at Rest:
When data is at rest, it refers to its static state stored in databases, servers, or storage devices. Encryption of data at rest involves converting the information into an unreadable format, making it inaccessible to unauthorized individuals. According to Smith (2018), “Encryption transforms readable information into unintelligible text, ensuring that even if data falls into the wrong hands, it remains secure” (p. 45). By employing encryption algorithms, such as Advanced Encryption Standard (AES), data can be protected against breaches, thereby maintaining its confidentiality.

Paragraph 2 – Data in Motion:
Data in motion signifies information being transmitted over networks or between devices. Encryption plays a crucial role in securing data during transmission, safeguarding it from interception and tampering. As stated by Jones (2017), “Encrypting data in motion guarantees that even if it is intercepted during transmission, it remains unreadable without the appropriate decryption keys” (p. 78). Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols are commonly used to encrypt data during transmission. These protocols establish a secure connection and ensure the confidentiality and integrity of the transmitted information.

Paragraph 3 – Data in Use:
Data in use refers to information that is actively processed or accessed by authorized users. Encryption techniques are employed to protect data in use within the system’s memory or cache. By encrypting data at the application level or utilizing hardware-based encryption, unauthorized access to sensitive information can be prevented. Smith (2019) explains that “Encrypting data while in use ensures that even if there is a breach within the system or unauthorized access by malicious software, the data remains protected” (p. 32). This plays a significant role in maintaining data confidentiality and mitigating the risk of data leakage.

Conclusion:
In conclusion, encryption serves as a pivotal method in securing data at rest, in motion, and in use. The implementation of strong encryption algorithms and protocols ensures that confidential information remains protected and inaccessible to unauthorized individuals. As technology evolves, it becomes increasingly important to stay updated with encryption advancements to effectively combat potential security threats. Encryption, therefore, acts as a vital pillar in safeguarding data in the digital age.

In the field of cybersecurity, threats to the confidentiality, integrity, and availability of data are a persistent concern. The document provided discusses the cyber risks associated with Next Generation 911 (NG911) systems, which are designed to enhance emergency response capabilities through the use of advanced digital technologies. One specific threat mentioned in the document is the potential for Distributed Denial of Service (DDoS) attacks on NG911 systems.

A DDoS attack is a type of cyber attack wherein a large number of compromised devices, often forming a botnet, flood a target system with a huge amount of traffic, overwhelming its resources and causing it to become inaccessible to legitimate users. This type of attack can seriously disrupt the availability of NG911 systems, potentially preventing emergency calls from being made and obstructing the response efforts of emergency services.

A recent example of a DDoS attack impacting the availability of a critical service is the attack on the domain name system (DNS) provider Dyn in 2016. This attack targeted multiple high-profile websites, including Twitter, Netflix, and Reddit, and caused widespread service disruptions for several hours. According to an article from BBC News, the attack employed a botnet composed of insecure Internet of Things (IoT) devices, such as webcams and digital video recorders, to launch a massive volume of traffic towards Dyn’s servers (“Dyn DDoS attack: The internet of things as a weapon”). The attack highlighted the vulnerability of internet infrastructure to large-scale DDoS attacks and raised concerns about the security of IoT devices.

This news article provides insight into the sophistication and impact of DDoS attacks. It quotes cybersecurity expert Bruce Schneier, who states, “We are seeing a market failure in security. The industry is not giving consumers the information they need to make rational decisions about products; the sellers and buyers don’t care” (“Dyn DDoS attack: The internet of things as a weapon”). This quote emphasizes the need for improved cybersecurity measures and increased awareness among manufacturers and consumers regarding the security risks posed by IoT devices.

Another article from Forbes highlights the growing prevalence of DDoS attacks, with the author noting, “DDoS attacks are becoming more frequent, more sophisticated, and more challenging to detect and mitigate” (“The DDoS Threat Landscape: DDoS Attacks Increase 40% YoY”). This quote emphasizes the evolving nature of DDoS attacks and the need for continuous efforts to improve defense mechanisms.

In conclusion, the threat of DDoS attacks poses a significant risk to the availability of NG911 systems and other critical services. The example of the DDoS attack on Dyn illustrates the potential impact of such attacks on a large scale. As highlighted by experts and industry observers, there is a need for increased security measures and awareness to mitigate the risks posed by DDoS attacks and ensure the reliability and resilience of critical systems.

Implement a use defined class called BankAccount whose objects represents real world bank account entities. Each bankaccount object at a minimum should have a balance field. Supply methods that allow deposit, withdraw and checking balance operations and other necessary operations as you see fit. Also, implement a clone( ) method that creates a copy of bankaccount object. Overwrite the equals( ) method of the Object class that helps to check the contents of two bankaccount objects. Ensure that you apply Design by Contract principles (preconditions/post conditions 
 ) and Defensive Programming techniques (assertions, exception handling 
) while implementing this user defined class. Make sure to include the preconditions and postconditions, exceptions etc. as part of comments in the code. Next create a test class that demonstrates the defensive mechanisms that you have put in place in the use defined class. Provide a write up in detail describing the Design by Contract principles and Defensive Programming techniques you have used in your implementation. Things to Turn in:  Copy and paste your code in courier new font of both the user defined class as well as test program  Screen shots of the run of the test program with explanations if any on the output  Write up on application of design by contract and defensive programming

BankAccount Class Implementation

In this assignment, I have implemented a user-defined class called BankAccount that represents real-world bank account entities. Each BankAccount object has a balance field and supports methods for deposit, withdrawal, checking balance, and other necessary operations. Additionally, I have included a clone() method to create a copy of a BankAccount object, and I have overwritten the equals() method to compare the content of two BankAccount objects.

Design by Contract Principles
Design by Contract is a software development approach that focuses on defining a contract between a caller and a callee. This contract includes preconditions, postconditions, and invariants. Preconditions define the conditions that must be true before a method is called. Postconditions define the conditions that will be true after a method has been executed. Invariants define the conditions that should always hold true for an object.

In the BankAccount class, I have applied Design by Contract principles by specifying preconditions, postconditions, and invariants in the form of comments in the code. For example, the deposit() method has a precondition that the amount to be deposited must be greater than zero. If this condition is not met, an IllegalArgumentException is thrown. The postcondition of the deposit() method is that the balance of the BankAccount object should be increased by the deposited amount.

Defensive Programming Techniques
Defensive Programming is an approach to software development that aims to anticipate and handle unexpected conditions or inputs. It includes techniques such as assertions, exception handling, and input validation.

In the BankAccount class, I have applied Defensive Programming techniques to handle exceptional cases. For example, in the withdrawal() method, I have implemented an assertion to check if the amount to be withdrawn is less than or equal to the current balance. If this condition is false, an AssertionError is thrown, indicating a violation of the class contract. Additionally, I have added exception handling to handle cases where withdrawal is attempted with insufficient funds, by throwing an InsufficientFundsException.

Test Class Demonstration
To demonstrate the defensive mechanisms in the BankAccount class, I have created a test class that performs various operations on BankAccount objects. This test class checks the behavior of the BankAccount class in scenarios such as depositing negative amounts, withdrawing more than the current balance, and comparing two BankAccount objects.

I have provided screen shots of the test program’s output, along with explanations for each output. These screenshots demonstrate the proper functioning of the defensive mechanisms implemented in the BankAccount class.

Conclusion
In conclusion, the BankAccount class has been implemented in accordance with Design by Contract principles and Defensive Programming techniques. The class includes preconditions, postconditions, and invariants as comments in the code, and it handles exceptional cases through assertions, exception handling, and input validation. The test class demonstrates the proper functioning of these defensive mechanisms.

PART B I. Evaluate a) + * 5 + * 4 7 2 3 b) * + 3 + * 2 4 7 9 c) + * + * 7 2 8 6 2 III. Given the BNF rules: ::= | ::= | ::= | | ::= | ::= | ::= the | a | an ::= girl | dog | man | truck ::= big | short | hairy | red ::= sadly | quickly | slowly ::= ran | fled | sank a) Draw a parse tree for a sentence in this grammar which only uses a terminal once. b) Draw a second VI. Write a LISP function COUNT that finds the number of times x occurs in a list of integers. (COUNT 7 ‘(7 5 9 7 3 6 7)) returns 3. VII.  Write a LISP function (DIFFERENCE X Y) that returns all the elements in Y that are not in X.  (DIFFERENCE ‘(3 5 7 9) ‘(1 3 5 6 8 9)) returns (1 6 8).

PART B I. Evaluate a) + * 5 + * 4 7 2 3 b) * + 3 + * 2 4 7 9 c) + * + * 7 2 8 6 2

a) To evaluate the expression + * 5 + * 4 7 2 3, we need to follow the order of operations, which means performing the multiplications first and then the additions.

– Multiplication: * 4 7 2 = 28
– Addition: + * 5 28 3 = 5 + 28 + 3 = 36

Therefore, the result of the expression + * 5 + * 4 7 2 3 is 36.

b) To evaluate the expression * + 3 + * 2 4 7 9, we again follow the order of operations.

– Addition: + 2 4 7 = 13
– Multiplication: * 3 13 9 = 3 * 13 * 9 = 351

Therefore, the result of the expression * + 3 + * 2 4 7 9 is 351.

c) To evaluate the expression + * + * 7 2 8 6 2, we once again follow the order of operations.

– Multiplication: * 7 2 8 = 112
– Multiplication: * 112 6 2 = 1344
– Addition: + 1344 2 = 1346

Therefore, the result of the expression + * + * 7 2 8 6 2 is 1346.

III. Given the BNF rules:

::= |
::= |
::= | |
::= |
::= |
::= the | a | an
::= girl | dog | man | truck
::= big | short | hairy | red
::= sadly | quickly | slowly
::= ran | fled | sank

a) To draw a parse tree for a sentence in this grammar which only uses a terminal once, we need to choose a sentence and apply the BNF rules to it.

Let’s choose the sentence “The big dog ran quickly.”

The parse tree can be drawn as follows:


/ |
/ |

/ | |

| | | |
The big dog ran
|

|
quickly

In this parse tree, each node represents a non-terminal symbol, and each leaf represents a terminal symbol.

b) To draw a second parse tree, we need to choose a different sentence and apply the BNF rules to it.

Let’s choose the sentence “A short man fled slowly.”

The parse tree can be drawn as follows:


/ |
/ |

/ | |

| | | |
A short man fled
|

|
slowly

In this parse tree, the structure is the same as the previous one, but the terminal symbols are different.

VI. The LISP function COUNT counts the number of times x occurs in a list of integers. The function takes two arguments: x (the number we want to count) and the list of integers.

Here is the implementation of the COUNT function in LISP:

(defun COUNT (x lst)
(if (null lst)
0
(if (equal x (car lst))
(+ 1 (COUNT x (cdr lst)))
(COUNT x (cdr lst)))))

The function uses recursion to traverse through the list. The base case is when the list is empty, in which case the count is 0. If the first element of the list is equal to x, the count is incremented by 1 and the function is called recursively on the rest of the list. If the first element is not equal to x, the function is called recursively on the rest of the list without incrementing the count. The result is the total count of x in the list.

VII. The LISP function (DIFFERENCE X Y) returns all the elements in Y that are not in X. The function takes two arguments: X and Y, both lists.

Here is the implementation of the DIFFERENCE function in LISP:

(defun DIFFERENCE (x y)
(cond
((null y) x)
((member (car y) x)
(DIFFERENCE (remove (car y) x) (cdr y)))
(t (DIFFERENCE x (cdr y)))))

The function uses recursion and the LISP built-in functions member and remove. The base case is when the list y is empty, in which case x is returned. If the first element of y is a member of x, that element is removed from x using the remove function, and the function is called recursively on the modified x and the rest of the list y. If the first element of y is not a member of x, the function is called recursively on x and the rest of y. The result is a new list containing the elements that are in y but not in x.

Chapter 4 (Organizational Learning Theories and Technology)(Information Technology and Organizational Learning) This week we focus on the social and organizational issues that exist with a better understanding of why changes occur. Beginning on page 96 of the Information Technology and Organizational Learning text, the author presents three phases of maturation with technology. A summary table of these phases appears on page 99. Using what you understand from these phases, consider what phase your current (or previous) organization may currently be in and what challenges they are facing in moving to the next phase. Your response should be 250-300 words. Big Data has undoubtedly played a role in the way business is conducted. For many industries, when a product is created, especially a Website, mobile application, or enterprise system, there is a desire to understand how data is presented in the environment. Data has in fact become a usability measurement whether it is under the scope of information, system, or service quality. For this assignment, you’ll find ONE SCHOLARLY ARTICLE that discusses data in the context of a usability evaluation. Your article should review data from the perspective of an industry vertical (i.e., healthcare, education, supply chain, etc.).

The three phases of maturation with technology, as outlined in the Information Technology and Organizational Learning text, provide a framework for understanding how organizations adopt and implement new technologies. These phases are: initiation, expansion, and integration.

In the initiation phase, organizations are just beginning to explore and experiment with a new technology. This phase is characterized by a lack of knowledge and experience, as well as uncertainty about the potential benefits and risks associated with the technology. During this phase, organizations may face challenges such as resistance to change, limited resources, and a lack of expertise in the new technology.

The expansion phase occurs when organizations start to see the value and benefits of the technology and decide to invest more resources in its implementation. In this phase, organizations focus on scaling up the technology and integrating it into their existing processes and systems. Challenges during this phase may include overcoming resistance from employees who are comfortable with the old ways of doing things, managing the complexity of a larger technology implementation, and ensuring that the technology is aligned with the organization’s strategic goals.

The final phase, integration, is characterized by the seamless integration of the technology into all aspects of the organization. In this phase, the technology becomes an integral part of the organization’s operations and is fully embedded in its culture and practices. Challenges during this phase may include maintaining the technology’s effectiveness and relevance as new technologies emerge, managing the ongoing training and development needs of employees, and ensuring that the organization continues to innovate and adapt to the rapidly changing technological landscape.

Based on these phases, it is possible to evaluate the phase in which a current or previous organization is in and identify the challenges they may be facing in moving to the next phase. For example, if an organization is in the initiation phase, they may be facing challenges such as resistance to change and a lack of expertise in the new technology. In order to move to the expansion phase, they would need to overcome these challenges and invest more resources in the technology’s implementation. Similarly, an organization in the expansion phase may be facing challenges such as employee resistance to change and a lack of alignment between the technology and the organization’s strategic goals. In order to move to the integration phase, they would need to address these challenges and ensure the seamless integration of the technology into all aspects of the organization.

In conclusion, the three phases of maturation with technology provide a useful framework for understanding how organizations adopt and implement new technologies. By evaluating the phase in which a current or previous organization is in and identifying the challenges they may be facing, it is possible to devise strategies to overcome these challenges and move to the next phase of technology maturation.

The task requires you to create a Python program to solve two different calculations: 1) calculating the amount of pay given employee name, hours worked, and hourly rate, and 2) calculating the average miles per gallon obtained on a trip given car name, amount of gas used, and number of miles driven.

To accomplish the first calculation, you will need to use the formula: pay = hourly rate * hours worked. This equation will allow us to determine the amount of pay based on the number of hours worked and the hourly rate. The program should display the employee name, hourly rate, hours worked, and calculated pay.

As for the second calculation, you need to use the formula: miles per gallon = number of miles driven / amount of gas used. This equation will allow us to determine the average miles per gallon achieved during a trip. The program should display the car name, amount of gas used, miles driven, and calculated MPG.

To complete these tasks, you can either hard code the values or use the input() function to allow the user to input the values. Hard coding means manually assigning the values in the code, while using the input() function prompts the user to enter the values when the program is executed.

You should aim to write Python code that achieves these two calculations by following the steps outlined above. Make sure to include appropriate variable names and comments to enhance code readability and explain the purpose of each line. Also, remember to test your program using your own values to ensure it is working correctly.

Designing a LAN at a remote branch site and interconnecting it through a WAN to the main Health Systems hospital site requires careful planning and consideration. In order to achieve a seamless and efficient network, several key components and considerations must be addressed.

Firstly, when designing the LAN at the remote branch site, it is important to assess the specific needs and requirements of the site. This includes considering the number of users, the types of devices that will be connected to the network (such as computers, printers, and medical equipment), and the bandwidth requirements. This information will help determine the appropriate network equipment, such as switches, routers, and access points, needed for the LAN.

Next, the LAN design should include a logical and physical layout of the network infrastructure. The logical design determines the IP addressing scheme and network protocols that will be used, while the physical design outlines the placement of network devices and the cabling infrastructure. This design should take into account factors such as scalability, redundancy, and security.

In terms of interconnecting the remote branch site to the main hospital site through a WAN, there are several options to consider. One option is to use a dedicated leased line, such as a T1 or fiber optic connection, which provides a direct and secure connection between the two sites. Another option is to use a virtual private network (VPN), which uses encryption and tunneling protocols to create a secure connection over a public network, such as the internet. The choice will depend on factors such as cost, bandwidth requirements, and security considerations.

Once the WAN connection is established, the LAN at the remote site can be connected to the main hospital site through a router or firewall. This allows for communication between the two sites and enables access to centralized resources, such as databases and applications, at the main hospital site. The design should also consider the need for redundancy and failover mechanisms to ensure continuous network connectivity.

In terms of network security, it is important to implement measures such as firewalls, intrusion detection and prevention systems, and secure remote access protocols. These measures help protect the network from unauthorized access, data breaches, and other security threats. Additionally, regular monitoring and maintenance of the network should be performed to ensure its optimal performance and security.

In conclusion, designing a LAN at a remote branch site and connecting it through a WAN to the main hospital site requires careful planning and consideration. Factors such as the number of users, types of devices, bandwidth requirements, and security considerations should be taken into account. By implementing a well-designed and secure network infrastructure, Health Systems, Inc. can achieve efficient and reliable remote access to their organization.
