...Project Scope Creep | | [Type the author name] | [Pick the date] | Colquitt, J. and Lepine, J. (2013) “Stress.” Organizational Behavior: Improving Performance and Commitment in the Workplace, 130-142. The authors focus on the research field of organizational behavior and understanding attitudes and behaviors of individuals and groups within organizations with the goal of improving them and the way the function collectively. The section on stress analyzes the negative impacts that stress can exert on organizations and methods for managing it to minimize its effect. The foundation of the section revolves around the “transactional theory of stress” which explains how stress is perceived and how individuals respond to it, taking into account the effects of both work and non-work influences on the overall organization. Due to the high cost organizations are faced with associated with employee stress, the section analyzes different practices and methods that can be utilized to manage stress and eliminate issues that cause it. Additionally, a number of different companies and their stress management practiced are discussed as well as resources that can be used to aid organizations. This book is an excellent resource and reference tool for project managers as they face a unique set of challenges based upon the nature of projects and the functionality of project organizations. The stress section was particularly beneficial in describing the stressful effects that scope creep...

...Project scope defines the objective associated with project completion with possible resources and requirements. Project scope creep is known as deviation from the planned scope due to unavoidable circumstances/forces. These mainly causes due to change in selected/required technology, modification in applicable rules, increase in knowledge base of the project (Meredith & Mante, 2009). Project Manager (PM) must maintain a consistent focus on the scope of the project along with all the factors affecting positively or negatively on the performance/growth of the project. Project scope should be controlled throughout the project life cycle. Factor indicating the sneak from the scope should be immediate highlighted and appropriate action to obtain the desired / planned outcomes of the project should be triggered if deviation exceed acceptable limit. Delay in recognition of scope creeping factors would change the outcomes at the completion of the project or even can cause stoppage or cancelling of the project. Furthermore, if project faces unavoidable circumstances that make some amendments in project scope inevitable for the continuity of project, then PM must take stakeholders in confidence and properly communicate the unavoidable forces with their affect on project along with proposed changes in scope of the project (Project Smart, 2013). Project manager is responsible for successful completion of the project according to the plan, with allowed resources and within given time....

...block is a set of statements that belong together as a group, and are performed any time the function is executed. When a function is executing, what happens when the end of the function block is reached?When a function is executing, it 'returns' when the end of the block is reached - meaning the interpreter jumps back to the part of the program that called the function, and the program resumes execution at that point. What is a local variable? What statements are able to access a local variable?A local variable is a variable that is declared inside of a function. Only statements in the same function can access a local variable. What is a local variable's scope?A local variable's scope is the part of a program in which the variable may be accessed and is only visible to the statements in the variable's scope. Why do global variables make a program difficult to debug?Global variables make a program difficult to debug because any statement in a program file can change the value of a global variable. If you find that the wrong value is being stored in a global variable, you have to track down every statement that accesses it to determine where the bad value is coming...

...Using Global Variables Global Variables Global variables are used in applications in programming. There are advantages and disadvantages to using these variables. Using global variables has its advantages in some forms of applications, while using them in others would make using them more difficult. Global variables are useful when you need to share a function with all functions in an application. Global variables can be easier to identify in an application by giving them a unique name, so that other programmers can see they are working with a global variable when maintaining your application. On small programs such as widgets or gadgets it may be easier to use global rather than passing around local variables. Using a global variable means that other functions cannot update it. Another advantage to global is that they can be accessed from anywhere in the program. Some are also disadvantages to using global variables. Global variables can create mutual dependencies, with an increase in dependencies the complexity of the code increases. Any function can access a global variable in the program so a change in the program at one point can change values everywhere. Global variable also slow down performance speed a little. Using global variables makes reusing parts of the script impossible. Global variables also make tracking a bug much harder. When declaring a global variable in a flowchart, you would but the variable in the main part of the program, hence the box the...

...Unit 4 Homework 1. What are the five advantages and disadvantages of using global variables? Advantages * It is accessible to all modules in a program * You only have to declare it once outside the modules * It is good to use it for constants you want to keep consistent * It simplifies maintenance, avoids duplication of local constants * It can make a program easier to read in reference to constants Disadvantages * It makes debugging difficult * If modules use global variables it is dependent upon the module and if other modules are presented you have to redesign all over each time. * Any statement in a program can change the variable * It makes a program hard to understand since it can be modified and have to be aware of all other parts of the program that access it. * Global variables are not willing direct into flowcharts 2. How can you declare global and local variables in flowcharts? * Global variables are displayed in pseudo code but not in flowcharts directly In order to declare global variables in a flowchart, you’d put that variable in the main part of the program (the main box where other functions will branch off from) for local variables, you’d put those variables in the box where each separate functions executed. 3. What is the main difference between global and local variables? * A global variable applies to the entire application you are writing as for a local variable it could only apply for the section you are programming...

So if we take the exclusive-or of two integers, the result has a one in every bit position in which the numbers differ, and zeroes everywhere else. public static int hammingDistance(int a, int b) { int count = 0; // bits has a one wherever a and b differ int bits = a ^ b; while (bits != 0) { if ((bits & 1) == 1) // is the low bit one? ++count; bits = bits >>> 1; // done w/this bit } // while something’s nonzero return count; } // hammingDistance() This simplified the loop condition and took one shift out of the loop body. 5 Hamming Distance—Final Version It turns out we can simplify things a bit more through the use of the Java library. public static int hammingDistance(int...

...Derek Taylor 24 July 2015 Homework Assignment & Research Assignment 1.) What is the difference between Application Software and System Software? (Give an example of both) System software is an integral part that aids in the computer’s functioning. It manages the computer resources in ways that they can operate in tandem. System software provides a platform for the execution of application software. Examples of system software are BIOS and firmware. Application software is created for users. They manage their specific tasks to suit their needs like a media player of word processors. Examples of application software are CRM software, ERP software, accounting, graphics, and media software. 2.) What does it mean when we say that an interpreter both “Translates and Executes” Instructions? In the case of the interpreter, it translates and executes each line of codes one line at a time. Thus if the program has syntax errors (violation of program rule) lower down in the code, you never know until the interpreter reaches to that statement. 3.) Explain the “fectch-decode-execute” cycle. In the first step, fetch instruction, the processor fetches the instruction from the memory. The instruction is transferred from memory to instruction register. The processor is ready to fetch instruction. The instruction pointer contains the address 0100 contains the instruction MOV AX, 0. The memory places the instruction on the data bus. The processor then copies...

...Disadvantages and Advantages of Using Global Variables The disadvantages of using global variables is that it has a lack of access control which can hinder security when working with 3rd party plug –ins. Global variables can have unlimited mutual dependencies which can make the program complexed according and integrating modules can also be difficult because other software written may use the same global variable names and your intentions were to use a local variable, creating name – space pollution. For example, if you are using a module and have to link it with another module, you will get linking errors because there are multiples of the same global name and it may not be thread safe. (Wiki.com). Global variables can be modified or read in any part of the program making it difficult to remember its use, according to Wiki.com/c2. The advantages of using global variables is that they are accessible anywhere in the program, they are declared at the beginning of the program by a global command and you can call them anywhere in the code. Use global variables in a public static field so it can be called anywhere in the programming and it will clog name space usage, (programmer.stachexchange.com). Common data can be declared global so you don’t have to use parameter passing. And because you can use it anywhere, use encapsulation to avoid corruption in the program, (yahoo.com). Global variables are in the assignment window while local variables are in the input box is how...

...Unit 4 Research 1: Using Global Variables Advantages of using Global Variables * Global variable belongs to every function in the program. * Avoid passing frequently-used variables between several functions. * A global variable is accessible in every scope. * A global variable can potentially be modified from anywhere. * It can be accessed from any other files using extern. Disadvantages of using Global Variables * Non-locality -- Source code is easiest to understand when the scope of its individual elements is limited. Global variables can be read or modified by any part of the program, making it difficult to remember or reason about every possible use. * Implicit coupling -- A program with many global variables often has tight couplings between some of those variables, and couplings between variables and functions. Grouping coupled items into cohesive units usually leads to better programs. * Concurrency issues -- if globals can be accessed by multiple threads of execution, synchronization is necessary (and too-often neglected). When dynamically linking modules with globals, the composed system might not be thread-safe even if the two independent modules tested in dozens of different contexts were safe. * Namespace pollution -- Global names are available everywhere. You may unknowingly end up using a global when you think you are using a local (by misspelling or forgetting to declare the local) or vice versa. Also, if you ever have to link...
