PERT vs. CPM in Project Management

Comparison of CPM and PERT – Differences and similarities
There are many sizes to a project, including complex, small, or large. Any project manager must create a plan that will allow the project to be completed within a specified time. Project management tools for efficient project management include PERT and CPM.
CPM stands to Critical Path Method and Pert for Program Evaluation Review Technique.
The Critical Path Method is a method for project management that schedules project tasks. The Program Evaluation Review Technique is a tool for project management that calculates the time required to complete project activities successfully.
Critical Path Method (CPM).

The time management aspect of project management includes the critical path method. CPM is a tool that allows you to create and manage a project schedule. This method calculates the start and finish dates for a project using multiple analytical techniques such as the critical path, critical chain, and resource optimization.
CPM is used for estimating the minimum duration of a project and the minimum resource consumption. This allows for flexibility in project activities and routes. This does not take into account resource limitations.
Flexibility in a schedule can be measured by how long a scheduled activity takes to complete from its start date. This is called “Total Float.” This method can be used to create a negative, zero or positive total floating depending on the constraints.

Understanding the differences between CPM and PERT

PERT and CPM have many similarities in project management. However, the following differences distinguish PERT from CPM.
Program Evaluation Review Technique
Method of Critical Path
Analytic project management is used to determine the exact time it takes for the team to complete the project successfully by managing undefined activities.
An analytical approach to project management that helps in planning the project with a specific start and end date, as well as undertaking the predefined activities.
It is an event-oriented method.
It is an activity-oriented method.
It optimizes project time.
It optimizes resources.
Both critical and non-critical activities can be considered the same.
There is a distinction between critical and non-critical activities.
It is a model for probability.
It is a deterministic system.
It is best suited to non-repetitive events.
It is ideal for repetitive activities in projects.
It does not replicate activities.
It used replicated activities as a way to show the structure of the activities.
Time uncertainties do not cause events to crash.
Structure of activates crashes, as time uncertainties are not present
These are best suited to research and development projects.
These are best suited to construction and development projects.

Program Evaluation Review Technique (PERT)
Program Evaluation Review Technique (PERT), is a method for project scheduling and estimating. It is a probabilistic technique that indicates the expected time to complete the project.
This technique cannot be used to estimate when the project will be completed. It takes into account all uncertainties and all risks. It is a probabilistic network analysis technique that can be used to plan and schedule unpredicted project activities.

PERT vs. CPM-Applications
PERT and CPM share many similarities. They can be used in various areas of network analysis. These are the most common applications of CPM and PERT.
Marketing programs
– Marketing new products
– Establishing new industries.
– Scheduling future projects.
– Large-scale production control.
– Maintenance of resources for a project.
– Planning for the production of new products.
– Management of advertising campaigns.
– Construction, research and development projects
– Maintenance of resources such as financing and staff.

Advantages of PERT vs. the CPM
CPM was created in 1957 and PERT in 1958. Because of their lack of disadvantages, and the large number of benefits, they have been in widespread use for a long period of time.


Optimize resource consumption
– Increases product productivity
– A CPM predicts the impact of activity on a project.
– This tool will help you create a detailed map that includes all details for your project.
– Can be used for reducing the cost and time involved in a project.
– It is easy to measure and organize project tasks using a timeline.
– A PERT Chart helps you to logically process, assign, manage and manage resources.

PERT vs. the CPM – Disadvantages

– Good knowledge is required to understand the generated chart.

Why is PERT important?

PERT is a project management tool that helps to plan, organize, estimate, coordinate and coordinate tasks within a project. PERT stands for Program Evaluation Review Technique. This methodology was developed by the U.S Navy in the 1950s to manage its Polaris submarine missile program.
There are two versions.
PERT Chart – Used for project scheduling
Three point estimation is also known as PERT estimation.
Pert Chart
A PERT chart is a visual representation of a project. It is similar to a network chart. It consists of numbered nodes in the form of rectangles or circles, which represent events or milestones in the project. These nodes are linked by labelled vectors, or directional lines, which represent tasks in the project.
The direction of the arrows along the lines defines the sequence of tasks. The following diagram shows an example of a PERT Chart.
It is important to complete the tasks between nodes 1, 2, 4, 8 and 9 in a specific order. These are known as dependent or serial tasks.
The tasks between nodes 1, 2, and 3, are not dependent on one another and can be done simultaneously. These tasks are known as concurrent or parallel tasks.

Tasks that must be completed in a specific order but don’t require resources nor completion time are called event dependency. These are represented as dotted lines with arrows, and are called dummy tasks. The dashed Arrow linking nodes 6 to 8 is an example.
The numbers on either side of the vectors indicate how much time was allotted for the task.
Although it is similar to Gantt charts, Pert chart can sometimes be preferred over Gantt charts. It is clear and easy to see task dependencies. PERT chart has a disadvantage. It’s more difficult to understand, especially when you are dealing with complex projects that have many dependencies. It all depends on how comfortable the Project Manager is with the tool.
PERT Estimation
This technique is also known as Three Point Estimation. This idea was inspired by the program evaluation and review method (PERT). PERT uses three estimates in order to determine an approximate duration for an activity.
Most likely (tM). This estimate is based upon the duration of the activity, the resources likely to have been assigned, their productivity, realistic expectations about availability for the activity and dependencies on other participants.
Optimistic (tO). Based on the best-case scenario, the duration of the activity is calculated.
Pessimistic (tP). Based on the worst-case scenario, the duration of the activity.
A formula can be used to calculate the expected duration based on the assumed distributions of values within the ranges of the three estimates. Triangular and beta distributions are two common formulas. These formulae are:
Triangular Distribution tE = (tO+ tM+ tP)
Beta Distribution (from the PERT traditional technique). tE = (tO+ 4tM + 6tP)
Three points with an assumed distribution are used to estimate the duration. They provide an estimated duration and help clarify the uncertainty surrounding the expected duration.

Learn about Jenkins Releases
Before we get into how to install Jenkins, let’s first look at the release lines. LTS and weekly are the two release lines for Jenkins. You can choose one or the other depending on your organization’s needs. Both release lines can be found with Docker containers, native packages, installers, war files, and Docker containers.
LTS (Long-Term Support) releases are chosen at an interval of 12 weeks after the regular releases. LTS releases are stable releases that are assumed to be stable for a certain period. These weekly releases are those that are created each week to deliver bug fixes and new features to plugin developers as well as users.
Get Started with the Installation
Let’s now look at the steps required to install Jenkins on a single machine or on a local machine. It is essential to note that the general operations of Jenkins follow a standalone application model with its own specific process with the in-built Java servlet container/application server. You should also know that Jenkins can be run in other Java servlet containers, such as Apache Tomcat and GlassFish, before you get started. However, advanced professionals will find the instructions for setting up such installations very useful. These steps will help you install Jenkins in different production environments.
Prerequisites for Jenkins Installation
Before we explain the installation process, the prerequisites are the most important information in any Jenkins tutorial. Let’s now look at the prerequisites for installing Jenkins.
Hardware Requirements
For Jenkins to be installed on an individual machine, it will require 256 MB RAM and 1GB hard drive space. It is important to note, however, that Jenkins can only be run as a Docker container if it has 1GB of hard drive space. For a small team, the hardware configuration should have more than 1 GB RAM. A small team should have a hard drive capacity of at least 50GB.
Software Requirements
Software requirements for Jenkins installation and configuration include references to Java, the web browser, and the operating system. For Java requirements, all new Jenkins versions must meet the following requirements.
Java 8 runtime environments include support for both 32-bit and 64-bit versions.
Jenkins does not support older Java versions such as Java 9, Java 10 or Java 12.
These requirements apply to all components of the Jenkins system, such as the Jenkins master and CLI agent, and all types of agents. Two JDKs (or JREs) are used by Jenkins project to perform a full test flow. These are OpenJDK JDK/JRE8-64 bits and OpenJDK JDK/JRE11-64 bits. You can use JRE/JDKs of other vendors on Jenkins without any restrictions.
Compatibility with Web Browser
Web browser compatibility is the next crucial aspect of installing Jenkins. There are three categories of web browsers that Jenkins supports. The first is that the first level of web browser qualification for Jenkins aims to fix browsers proactively and provide a similar user experience across all browsers. The second level of the web browser support model for Jenkins’ software requirements is the one that accepts patches to fix issues.
It should also show the best effort to ensure at least one method of performing any action. There are no guarantees at the final level of web browsers within the support model for Jenkins. This implies that Jenkins will accept patches from such browsers only if they’re low-risk. For Jenkins installation, Google Chrome, Apple Safari, and Mozilla Firefox are the best browsers.

How to Install and Configure Ansible

Automation is the most important intervention in the technology field. Automation of redundant tasks in manufacturing or business processes can lead to productivity improvements. Different tools and platforms for automating and managing automated systems and processes are essential. You need to know the basics of Ansible and its functions before you can install it.
Ansible, an open-source automation tool, is powerful and easy to use. It can be used for deployment, management, configuration, and management of software applications on nodes. Ansible can also serve as a configuration management software that administrators and operations systems use to maintain effective control over multiple servers.

Ansible is trusted despite the availability of many well-known configuration management systems like Chef and Puppet. This is due to the Ansible best practices, which are smaller overheads and more reliable. Ansible certifications are more popular among professionals. This discussion will provide insight into the process of installing and configuring Ansible. The report will also provide information on the workings and uses of Ansible to support the discussion.
Understanding the Workings of Ansible
This discussion should begin with the functioning of Ansible. Ansible is able to configure client machines on computers that have installed and configured Ansible components. Ansible uses the normal SSH channels to communicate with remote machines and copy files. Ansible doesn’t require any additional software to be installed on client computers.
Ansible could accept servers with an exposed SSH port, regardless of its stage in life. Ansible could work with any computer that can be administered via SSH. Before installing Ansible, it is important to be aware of the modular approach of Ansible.
The modular approach allows for the extension of functionalities of the main systems to address specific scenarios. Modules can be written in any language. Communication between modules follows the JSON standard. Because of their expressive nature and similarity with other markup languages, the configuration files are primarily documented using the YAML data serialization format.
Ansible allows interaction with hosts via configuration scripts and command-line tools. Playbooks are the name of configuration scripts and are mentioned in nearly every Ansible tutorial. DevOps engineers and system administrators should be involved in managing complex IT infrastructure across multiple sites and on the cloud.
Modern applications that have a front-end service, a database service, or an APO service are complex systems to manage. Complex systems can lead to errors and more time consumption. Ansible offers IT automation to automate the provisioning and deployment of IT infrastructure, as well as managing changes to services configuration.
Ansible’s IT automation approach is largely based on the ‘playbook. A closer look at any Ansible tutorial will reveal that the Ansible playbook acts as a recipe. The Ansible playbooks provide instructions on how to set up your IT infrastructure, deploy applications, and configure services.
Ansible is very popular due to its easy learning curve. An important feature to note before installing Ansible is its agentlessness. You don’t need to install or manage Ansible clients on managed nodes. This functionality makes it much easier to manage Ansible updates.
We have provided a detailed article about How Ansible Works.
Configuring and Installing Ansible
Before you install or configure Ansible, the prerequisites are what you need to be aware of. Ansible installation requires a control system. You should now know that Ansible can be installed on Ubuntu, Debian Linux Mint, Linux Mint or Fedora Linux distributions.
This is due to the fact that Windows machines cannot be used as control machines. Ansible uses SSH to manage remote machines. You must also consider the prerequisite of two or more Ubuntu Servers in order to install Ansible.
Two or more Ubuntu 18.04 servers will serve as one Ansible server. The remaining servers would be Ansible hosts. Each server should have a nonro

How to Improve the Performance of a Project Team

These projects are temporary and only last for a short time. The projects are designed to meet specific organizational needs, such as the development of new products or improving business processes. The success of projects depends on the selection of the right performance team. Project teams are made up of different members such as the client, business analyst and trainer, as well as the stakeholder, project sponsor, project leader, and stakeholder. Team leaders are key to the success of the team. Team leaders who are more skilled in performance management will ensure the success of the project. Leadership is crucial in project management. It is essentially about communication with team members. Project management is an important concept in business. It involves discipline to set goals and achieve them; to ensure that the project is completed on time and within the organization’s capabilities. Project management is an ongoing activity that continues throughout the project. It is the systematic management of resources in a way that the available resources deliver and execute the tasks required to complete the project within a specified time frame. The project manager is responsible for setting and achieving the goals using the best possible use of all resources, including time, cost, and workforce, throughout the project.
These methods can help improve the performance of project teams:
Setting expectations: It is important to understand the expectations and goals of the organization before you start a project. The team must be focused on achieving their goals. If the team is clear about what they are expected to do, they will be more engaged and find ways to improve their work performance.
Monitoring team performance: Organizational productivity can be used to monitor team activity. The best performing team is one that completes tasks within the timeframe and with the highest quality. The team must be able to increase productivity. Monitoring the team’s performance daily is important to ensure that they are working for the organization’s benefit and delivering outstanding results. You can manage the team’s performance by giving performance appraisals and having discussions about their performances. It is important to receive timely feedback on any unsatisfactory performances in order to take the appropriate steps to improve performance.
Training: Project management training is a great way to learn and manage projects while making the most of your resources. Project managers are taught how to use different tools within a project. The training is useful for project managers throughout the project. The training provides a foundation for the team to be able to contribute to various developmental activities.
Team Building Exercise: A project team is a group that works together towards a common goal. Team building is the process of empowering the project team to achieve the goals. A team building strategy that is effective is beneficial to the organization as it promotes productivity, project management excellence, and positive communication among the members. The team’s performance is influenced most by the project manager. A team building strategy can improve the performance of the entire team. The most powerful impact on team performance can be made by a consistent and enthusiastic application team building strategies. This is because the performance of the whole team is dependent upon the group of people, and not on any individual. The main purpose of team building exercises is to guide the team members to work together effectively in completing the assigned tasks.
