This document discusses several project scheduling and management techniques including Gantt charts, PERT charts, critical path method, critical chain scheduling, and using project management software. It provides descriptions and examples of each technique. Gantt charts track task progress visually on a timeline. PERT uses statistical analysis to estimate activity durations. Critical path method identifies the longest sequence of tasks. Critical chain scheduling accounts for limited resources by removing buffers and adding buffers to the project schedule. Project management software can help facilitate communications and schedule analysis if used properly.
Tools for project management is described some of the commonly used tools such as gantt chart, pert chart, logic network, product breakdown structure, work breakdown structure is defined briefly.

The changes required in the IT project plan for Telecomm Ltd would.docxmattinsonjanel
The changes required in the IT project plan for Telecomm Ltd would entail specific variation in the platforms used in the initial implementation plan. Initially, the three projects that were planned for implementation included; the installation of business intelligence platform, the implementation of Statistical Analysis System software technology, and the creation of an effectively network infrastructure. In this case, the changes would include an addition of an ERP software to ensure the performance of the workforce within the Telecomms Ltd employees.
ERP is an effectively coordinated information technology system that would ensure the company’s performance is enhanced. To understand how the implementation of a coordinated IT system offers a competitive advantage of a firm, it is essential to acknowledge three core reasons for the failure of information technology related projects as commonly cited by IT managers. In this case, IT managers cite the three reasons as; poor planning or management, change in business objectives and goals during the implementation process of a project, and lack of proper management support completion (Houston, 2011). Also, in the majority of completed projects, technology is usually deployed in a vacuum; hence users resist it. The implementation of coordinated information technology systems, such as ERP would provide an ultimate solution to the three reasons for failure, and thus would give Telecomms Ltd a competitive advantage in the already competitive market. Since the implementation of systems like ERP directly provides solution to common problems that act as drawbacks regarding the competitiveness of firm, it is, therefore, evident that its use place Telecomms Ltd above its rival companies in the market share (Wallace & Kremzar, 2001).
The use ERP, which is a reliable coordinated IT system entails three distinctive implementation strategies that a firm can choose depending on its specific needs. The changes in the projects would be as follows: The three implementation strategies are independently capable of providing a relatively competitive advantage for many companies. These strategies are: big bang, phased rollout, and parallel adoption. In the big bang implementation strategy, happens in a single instance, whereby all the users are moved to a new system on a designated (Wallace & Kremzar, 2001). The phased rollout implementation on the other hand usually involves a changeover in several phases, and it is executed in an extended period. In this case, the users move onto the new system in a series of steps (Houston, 2011). Lastly, the parallel adoption implementation strategy allows both legacy and the new ERP system to run at the same time. It is also essential to note that users in this strategy get to learn the new system while still working on the old system (Wallace & Kremzar, 2001). The three strategies effectively change the information system of Telecomms Ltd tremendously such that it positiv ...
New approach for solving software project scheduling problem using differenti...ijfcstjournal
Software Project Scheduling Problem (SPSP) is one of the most critical issues in developing software. The
major factor in completing the software project consistent with planned cost and schedule is implementing
accurate and true scheduling. The subject of SPSP is an important topic which in software projects
development and management should be considered over other topics and software project development
must be done on it. SPSP usually includes resources planning, cost estimates, staffing and cost control.
Therefore, it is necessary for SPSP use an algorithmic that with considering of costs and limited resources
can estimate optimal time for completion of the project. Simultaneously reduce of time and cost in software
projects development is very vital and necessary. The meta-heuristic algorithms has good performance in
SPSP in recent years. When software projects factors are vague and incomplete, cost based scheduling
models based on meta-heuristic algorithms can look better at scheduling. This algorithm works based on
the Collective Intelligence and using the fitness function, it has more accurate ability for SPSP. In this
paper, Differential Evolution (DE) algorithm is used to optimize SPSP. Experimental results show that the
proposed model has better performance than Genetic Algorithm (GA).

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Gantt chart
Introduction
invented Henry Gantt in 1910. Since the invention, Gantt
chart has come a long way.
A type of a bar chart used for illustrating project
schedules.
can be used in any projects that involve effort, resources,
milestones and deliveries.
Allow project managers to track the progress of the entire
project.
Can keep a track of the individual tasks as well as of the
overall project progression.
Can also be used for tracking the utilization of the
resources in the project. These resources can be human
resources as well as materials used.
4. The Use of Gantt chart
for project management purposes
First of all, the project should have a sufficiently
detailed Work Breakdown Structure (WBS).
Secondly, the project should have identified its
milestones and deliveries.
Gantt charts can be successfully used in projects of
any scale. When using Gantt charts for large
projects, there can be an increased complexity when
tracking the tasks.
This problem of complexity can be successfully
overcome by using computer software packages
designed for offering Gantt chart functionalities.
5. Tools Available of Gantt
chart
Dozens of Gantt chart tools can be used for successful
project tracking. These tools usually vary by the feature
offered.
The simplest kind of Gantt chart can be created using a
software tool such as Microsoft Excel.
If the project is small scale and does not involve many
parallel tasks, a spreadsheet based Gantt chart can be the
most effective type.
Microsoft Project is one of the key Gantt chart tools used
today.
There are many other Gantt chart tools available for free and
for price.
6. Program Evaluation and Review
Technique
Introduction
Before any activity begins related to the work of a
project, every project requires an advanced,
accurate time estimate. Without an accurate
estimate, no project can be completed within the
budget and the target completion date.
Developing an estimate is a complex task. If the
project is large and has many stakeholders, things
can be more complex.
PERT (Program Evaluation and Review Technique)
is one of the successful and proven methods among
the many other techniques, such as, CPM, Function
Point Counting, Top-Down Estimating, WAVE, etc.
PERT was created by the US Navy in the late 1950s.
7. The PERT Basics
PERT is all about management probabilities. Therefore, PERT involves in
many simple statistical methods as well.
Sometimes, people categorize and put PERT and CPM together. Although
CPM (Critical Path Method) shares some characteristics with PERT, PERT
has a different focus.
Same as most of other estimation techniques, PERT also breaks down the
tasks into detailed activities.
In this map, a node represents each event. The activities are represented
as arrows and they are drawn from one event to another, based on the
sequence.
8. The Three Chances of PERT
1. Optimistic Time Estimate (TOPT)
This is the fastest time an activity can be completed. For
this, the assumption is made that all the necessary
resources are available and all predecessor activities are
completed as planned.
2. Most Likely Time Estimate (TLIKELY),
Most of the times, project managers are asked only to
submit one estimate. In that case, this is the estimate that
goes to the upper management.
3. Pessimistic Time Estimate (TPESS)
This is the maximum time required to complete an activity.
In this case, it is assumed that many things go wrong
related to the activity. A lot of rework and resource
unavailability are assumed when this estimation is derived.
9. The PERT Mathematics
BETA probability distribution is what
works behind PERT. The expected
completion time (E) is calculated as
below:
E = (TOPT + 4 x TLIEKLY + TPESS) / 6

11. Critical Path Method
Introduction
Critical path is the sequential activities from
start to the end of a project
helps to find out the shortest path or critical
path to complete the project successfully.
If there is a delay in any of the activities under
the critical path, there will be a delay of the
project deliverables.
based on mathematical calculations and it is
used for scheduling project activities.
This method was first introduced in 1950s.
12. Key Steps in Critical Path
Method
Step 1: Activity specification
Step 2: Activity sequence establishment
Step 3: Network diagram
Step 4: Estimates for each activity
Step 5: Identification of the critical path
Step 6: Critical path diagram to show project
progresses
13. Critical Chain Scheduling
(CCS)
Critical chain scheduling is a method of
scheduling that takes limited resources into
account when creating a project schedule and
includes buffers to protect the project
completion date.
Critical chain scheduling assumes resources do
not multitask because it often delays task
completions and increases total durations
15. Buffers and Critical Chain
A buffer is additional time to complete a task
Parkinson’s Law states that work expands to fill the
time allowed. In traditional estimates, people often add
a buffer and use it if it’s needed or not
Critical chain schedule removes buffers from
individual tasks and instead creates
A project buffer, which is additional time added
before the project’s due date
Feeding buffers, which are addition time added
before tasks on the critical path
17. Reality Checks on Scheduling
Should have realistic schedule goals
Review the schedule
Preparation of detailed schedule
Seeking stakeholders’ approval
Don’t plan for everyone to work at 100% capacity all
the time
Alert top management well in advance if there are
schedule problems
Involvement and commitment from all team members,
top management, the customer, and other key
stakeholders
Progress meetings with stakeholders
18. Working With People Issues
Strong leadership helps projects succeed more than
good PERT charts
Project managers should use:
Empowerment
Incentives
Discipline
Negotiation
19. Using Software to Assist in Time
Management
Software for facilitating communications helps people
exchange schedule-related information
Decision support models help analyze trade-offs that
can be made
Project management software can help in various time
management areas
20. Words of Caution on Using Project
Management Software
Many people misuse project management software
because they don’t understand important concepts and
have not had good training
You must enter dependencies to have dates adjust
automatically and to determine the critical path
You must enter actual schedule information to compare
planned and actual progress
