Project Management Lifecycle
Project Management Lifecycle
Project Management is a tecnique to manage project effectively , that ensure the project objectives are met within scope,time,budget.Project Management Lifecycle (PMLC) create a systematic path to achive project goals.Project Management Lifecycle (PMLC) breaks down a project task into well-defined phases,each phase have some task that allow managers to monitor progress, allocate resources, and estimate risks at every phase of projects.
The lifecycle consists of five phases: Initiation, Planning, Execution, Monitoring , Controlling, and Closing.Each step has its separate role and significance.
Project Initiation Phase
The first and most critical phase ,here objectives are define first.Establish the purpose of the project and Identify expected outcomes and success probablitiy.
Example: A software company defining the goal of building an Patroll Software for a large Organisation.
Then Feasibility Study is done , cost-benefit analysis conducted ,technology, manpower, and budget is considered,risks is also calculated.Assign a qualified professional who will lead and communicate across teams (Project Manager).
Stakeholders (clients, sponsors, team, end-users) is also assigned in this phase.
Project Charter (objectives, scope, constraints, assumptions, stakeholders) is developed in this phase.
Project Planning Phase
This is the most critical and detailed phase of project management.
Define Scope
Create a Scope Statement that describes project boundaries.create a proper Work Breakdown Structure (WBS) to do the work into manageable tasks.
Develop Project Plan
Create a Project Management Plan covering schedule, cost, communication, risk, quality, and resources.
Budgeting & Cost Estimation
Estimate costs for resources, technology, licenses, and overhead.
Prepare a budget for monitoring expenses.
Schedule Development
Tools like Gantt Charts, PERT Charts, or Critical Path Method (CPM) is used to develop Schedule Development.
Resource Allocation
Identify team members, assign task and responsibilities.
Risk Management Planning
Calculate potential risks (technical, financial, environmental).
Quality Management Plan
Define quality control strategy.
Project Execution Phase
In this phase project is executed , that means work is performed, and deliverables like are created.
Team Mobilization
Assign roles and responsibilities formally and make sure that the team understands objectives and milestones.
Task Execution
Carry out project tasks as per the WBS and schedule.
Develop deliverables like output.
Resource Utilization
Allocate and monitor resources effectively to achive optimum output.
Communication & Collaboration
Have open communication across teams to remove any barrier and hasitation.
Tools like Slack, Trello, Jira are suitable for this phase.
Project Monitoring & Controlling Phase
- Cost variance (CV), Schedule variance (SV).
- Resource utilization efficiency.
- Quality defect rates.
- Monitor risk and maintain risk register.
- Prevent scope creep.
- Corrective Actions if required (schedule, cost, or resource) , any adjustment is necessary.
Project Closing Phase
- Deliverable Handover
- Transfer final products to the client.
- Compile project reports, risk registers, test reports, and financial statements.
- Release team members for new assignments.
- Identify successes, failures, and areas of improvement.
- Formal Closure

Critical Path Method (CPM)
Critical Path Method (CPM)
Critical Path Method(CPM) is a project management technique that identifies the longest path of tasks in a project ,this longest path determines the project duration.Critical Path Method(CPM) was developed in about 1950 for large, complex industrial projects,construction & IT projects. It is deterministic , that means assumes known task times.Where PERT is Probabilistic CPM is deterministic.CPM mainly focuses on time, not cost (cost can be added).
What are Advantage of Critical Path Method(CPM)
1) Produced clear project timeline.
2) Helps prioritize important tasks.
3) Improves resource allocation.
4) Supports cost-time trade-offs (crashing).
5) Enhances control on projects.
6) Enhance accountability of teams.
Limitations
1)Assumes fixed activity duration.
2)Less effective with uncertain estimates.
3)Network diagrams may become too complex.
4)Requires frequent updating.
5)Doesn’t directly handle resource constraints.
6)Can give misleading results if inputs are wrong.
7)Time-consuming for very large projects.
Terminology
- Activities = tasks in a project.
- Events = milestones marking task completion.
- Duration = estimated time to finish a task.
- Dependencies = order in which tasks must be done.
- Network diagram = visual representation of activities.
- Nodes = represent tasks/events.
- Arrows = represent dependencies.
- Path = sequence of activities from start to end.
- Critical path = longest path (in time).
- Non-critical paths = shorter paths with slack.
Here is a simple math on CPM
For A missible projects , here is the breatdown
Activity A : duration 4, start activity
Activity B : duration 3, depends on A
Activity C : duration 2, depends on A
Activity D : duration 5, depends on B
Activity E : duration 6, depends on C
Activity F : duration 2, depends on D and E (finish activity)
Forward pass — compute ES (Earliest Start) and EF (Earliest Finish)
ES of first activity = 0;
EF = ES + duration;
for an activity with multiple predecessors, ES = max(EF of predecessors).
Activity A: ES = 0 → EF = 0 + 4 = 4
Activity B: ES = EF(A) = 4 → EF = 4 + 3 = 7
Activity C: ES = EF(A) = 4 → EF = 4 + 2 = 6
Activity D: ES = EF(B) = 7 → EF = 7 + 5 = 12
Activity E: ES = EF(C) = 6 → EF = 6 + 6 = 12
Activity F: ES = max(EF(D), EF(E)) = max(12,12) = 12 → EF = 12 + 2 = 14
Project duration = EF(F) = 14 time units
Backward pass — compute LF (Latest Finish) and LS (Latest Start)
Activity D: successor is F (LS_F = 12) → LF_D = 12 → LS_D = 12 − 5 = 7
Activity E: successor is F (LS_F = 12) → LF_E = 12 → LS_E = 12 − 6 = 6
Activity B: successor is D (LS_D = 7) → LF_B = 7 → LS_B = 7 − 3 = 4
Activity C: successor is E (LS_E = 6) → LF_C = 6 → LS_C = 6 − 2 = 4
Activity A: successors B and C have LS 4 and 4 → LF_A = min(4,4) = 4 → LS_A = 4 − 4 = 0
Slack
Activity | Dur | ES | EF | LS | LF | Float |
---|---|---|---|---|---|---|
A | 4 | 0 | 4 | 0 | 4 | 0 |
B | 3 | 4 | 7 | 4 | 7 | 0 |
C | 2 | 4 | 6 | 4 | 6 | 0 |
D | 5 | 7 | 12 | 7 | 12 | 0 |
E | 6 | 6 | 12 | 6 | 12 | 0 |
F | 2 | 12 | 14 | 12 | 14 | 0 |
Critical path(s)
Path 1: A → B → D → F (4 + 3 + 5 + 2 = 14)
Path 2: A → C → E → F (4 + 2 + 6 + 2 = 14)

PERT Chart : Program Evaluation and Review Technique
PERT Chart : Program Evaluation and Review Technique
Full form of PERT Chart is "Program Evaluation and Review Technique" ,It is a project management tool.PERT chart is used to plan, schedule, and control complex projects.it was developed in the late 1950s byU.S. Navy during Polaris missile project.
PERT Chart is an event-oriented chart ,it focus on Focuses on events,it represents project activities visually.
1) Each activity is shown as an arrow.
2) Each event is shown as a node.
3) Nodes represent the start or completion of activities.
4) Identifies dependencies between tasks.
5) Estimates minimum project completion time.
6) PERT Chart is useful for projects with uncertainty and helps in decision-making.
7) PERT Chart emphasizes on time , while CPM emphasizes cost.
8) PERT Chart is read from left to right.
9) PERT Chart arrows indicate task order.
10) PERT Chart events are represented by circles/ellipses.
11) Suitable for R&D projects.Identifies dependencies between tasks.
Time Estimation in PERT Chart
PERT Chart uses three time estimates Optimistic time (O),Pessimistic time (P) ,Most likely time (M).
This formula reduces bias and gives weighted average when accounts for uncertainty (For R&D Projects).This makes estimation more realistic and can work wide ranges projects have higher risk.This identify probable completion time and Standard deviation is used for analysis.
Variance (σ²) = [(P – O) ÷ 6]².
Standard deviation (σ) = (P – O) ÷ 6.
Project variance = sum of variances on critical path.
Probability of completion can be calculated.
Formula:
Z = (Due Date – TE Project) ÷ σ
Higher Z = higher probability
Lower Z = lower probability
By PERT Chart
- Risk analysis becomes possible.
- Helps avoid unrealistic scheduling.
- Improves confidence in planning.
- Saves time and cost indirectly.
- Brings accuracy in complex projects.
How To Create PERT Chart
- Identify all activities of the project.
- Define dependencies between activities.
- List immediate predecessors.
- Draw network diagram.
- Place events (nodes) in correct order.
- Represent activities with arrows.
- Ensure logical sequence.
- Assign time estimates (O, M, P).
- Calculate expected time (TE).
- Identify critical path.
- Critical path = longest path in the network.
- Calculate earliest start (ES) for each activity.
- ES = earliest time an activity can begin.
- Calculate earliest finish (EF).
- EF = ES + activity time.
- Calculate latest finish (LF).
- LF = latest time an activity can finish without delay.
- Calculate latest start (LS).
- LS = LF – activity time.
- Find total float (slack).
- Float = LS – ES (or LF – EF).
- Zero float = critical activity.
- Positive float = non-critical activity.
- Negative float = project delay risk.
- Mark the critical path.
- Check project duration.
- Analyze variances and risk.
- Recheck logical sequence.

Availability of skill labor is another important factor of entrepreneurship.Human capital play a vital role for any industry , the availability of educated and skill labor effect the industry health and overall labor policy and productivity of a industry. Educated and skill labor reduce skills shortage problem and the problem of high labor cost and operational efficiency.
Economic stability is another important for set up a new business , inflammation currency stability , interest rate and political stability of is also play crucial role for entrepreneurship. If currency is not stable and country political stability is affected small business.
Cost of inputs & resources is another factor , this includes raw materials, energy, land, and labour.high input costs reduce margins and increase pricing risk, that leads frequent price spikes, supply bottlenecks, seasonal shortages, relocation of production to cheaper regions.
Non-Economical factors
Technology Advancement is also a part of entrepreneurship factor, Technology cal advancement create new industries and improve productivity, create new opportunity and reduce human effort . RND infrastructure Availability of skill labor is another important part of entrepreneurship.
Education is an tool to build knowledge ,education build skill and behavior of the community , it create critical thinking ,financial literacy ,exposure to entrepreneurship and Tec-savy man forece.

Interactive CSS Button Designer Tool – Free & Fast
What is Button ?
Button is an element of HTML. HTML is used to design Web Pages, Websites and Web applications. Here, the button is nothing but an element of HTML. The purpose of a button is to input some commands into the web application. It is generally a command giving an input element. For example, a user wants to "Save" some text, user will press the "Save" button. For example, a user to "Delete" something from a Web application, he will press the "Dele" Button. Buttons play an important role in Web Applications and Webpages. Also, button is used to Redirect Page from one page to another page. The early version of HTML was HTML and currently HTML5, from the beginning of HTML to HTML5, an input type button is supported.
Here is the syntax of a Button
<button type='button' >Click Me</button>
Designing the buttons is a very important part of Web Design. The color and text and appearance of the Button tell the user about the Button. For example, the "Save" button is green, which means the button is safe to use, no harm can be made to the Button. The Delete Button may be in red color to indicate the user, once data is deleted, it cannot be reverted back again.
Designing of a button is done generally by a CSS class. CSS stands for Cascading Style Sheet. The current version of CSS is CSS3.CSS is defined under a style tag, and it can be put on the same page or in a CSS file.CSS3 support transformation, rotation, animation etc. How CSS class is written, here is the example
<html>
<head>
<style>
.YouClass {
background-color: powderblue;
}
</style>
</head>
<body>
</body>
</html>
Very general property of a CSS is with, height, background color, front color, font type, font size ,here is an example of how this basic input are placed inside a CSS.
<style>
.YouClass
{
width :142px;
height :41px;
border-radius: 50px;
border-color: #FFFFFF;
background-color:#813d9c;
cursor:pointer;
text-align:center;
color:#FFFFFF;
font-size:17px;
font-family:Verdana;
}
</style>
Designing CSS for a perfect button is time taking. Designers have to change the attributes of the CSS, save it and open it in the browser and test again and again for making a CSS as per to imagine. Not only time taking but also requires a lot of patience, moreover CSS works differently in different browser, the appearance of an element become change when it appears in different browser, that is another problem of CSS design. To handle it, a lot of experience is required, and vendor-specific code is required for the design. A new developer takes a lot of time and embarrassing situation for the same.
To handle this situation, sonjukta.com presents "CSS Button Generator". This tool helps users to create beautiful CSS without knowledge of coding and deep experience Cascading Style Sheet. This tool allows users to drag and drop and choose option. The tool will create CSS automatically. This CSS is cross-browser comparable.
The main advantage of the tool is Live Preview. The user can experience changes while he is changing the slider. CSS generated by the tool will work uniformly on different browsers. The tool is completely Web-based, no installation is required. The tool is made up of open-source software like JavaScript and Mysql ,so you do not need any kind of license or permission from the vendor.CSS generated by the tool is completely royalty-free, and it is user property. The user can download or copy. This is an addition to his project.
In this tool there are eight tabs , each tab has different different functionality.
The "General Tab" is for the width, height, border, border radius, background color, padding, and margin of the button. These are the general properties of a button.
The next tab is "Text Tab" to control the design of text. For example, text alignment, font color, font size, style, font with font shadow property can be adjusted from here.
Next is "Gradient Tab". Gradient means multicolor background, a button can be multicolor and the color value or color intensity can be adjusted with slider gradient and gradient angle can be interested and Guardian color can also be changed from there.
Next is the "Hover tab". Hover means when a mouse or object is near to the element, the element will change its appearance by changing color or size or both. This property can be adjusted from this tab.
Next is "Padding". Padding is a property where padding can be adjusted, padding top, padding right, and margin can also be adjusted from this tab.
"Image" is a tab where the background image can be adjusted or users can put their own image in the background.
The next tab is "Symbol". "Symbol" is the unique feature of the tool. In the Button, you can insert symbols, there are multiple symbols. You can choose and change their color and please proper position where you need in your button. This is the unique feature of this tool. The button will get "base64" images.
The next is the "SVG" tab. SVG is vector graphics that create images like objects. Users can place multiple SVGs on the button. Users can change the color also.
One point must be noted that the "Symbol" inserted in the CSS does not include any external link for Symbol creation. Either Base64 or SVG are inserted locally. Base64 is an encoding pattern that can encode an image. Once the image is converted into Base64, it becomes a large string. In this tool, the provider uses Base64 encoding to avoid external image sources. It will make CSS a little bit larger, but there is no external dependency, CSS can perform its own. Another technique is SVG. SVG represents an image outline. The full form of SVG is vector graphics. This is created only as an outline. No inner fields are filled, they are only an outline color to represent a symbol of a specific object. This technique also avoids external sources.
Here is an example of image to Base64
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAC0AAAAdCAYAAAA+YOU3AAAAAXNSR0IArs4c
Here is an example of SVG
<svg width="48" height="48" viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
<title>Download</title>
<path d="M12 3v12m0 0l5-5m-5 5l-5-5" stroke="#000" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"/>

Effortless Slider Styling: Create Custom CSS Range Inputs in Seconds
What is Range Input range in HTML ?
Range Input is a control that is present in very early versions of HTML. Input Range is generally used for selecting range values. For example.
I can set a price range from 0 to 1000.
I can set the audio volume.
I can calculate the loan amount or interest rate.
For example, here is a color code range. The color code can be from 0 to 255 Red, Green and Blue. Three color codes are present there. Users have to set them, and users change the color code value, and the final color will be displayed. Thus, the HTML range is essential for Web Development and Web applications.
The basic Syntax of HTML range is
<input type="range" min="1" max="255" value="50" >
For our example, the minimum was zero(o) and the maximum value defined the maximum (255) and step defined the amount of value in each step. Here set one(1). One thing must be noted that the HTML Input Range also supports custom attributes. For example, I have an attribute called 'sonjukta'. An example is how custom attributes can be added to the control and how JavaScript can handle the custom attribute.
<input type="range" min="1" max="255" value="50" sonjukta="brightness-control" id="rangeInput">
<script>
const rangeInput = document.getElementById('rangeInput');
// Access the custom attribute
const sonjuktaValue = rangeInput.getAttribute('sonjukta');
// Example usage: log value change and custom attribute
rangeInput.addEventListener('input', function () {
console.log(`Value: ${this.value}, Sonjukta: ${sonjuktaValue}`);
// Example: Do something if attribute is 'brightness-control'
if (sonjuktaValue === 'brightness-control') {
document.body.style.filter = `brightness(${this.value}%)`;
}
});
</script>
Input Ranges appear differently in different browsers. When you open Mozilla and Chrome, you will notice the two designs are different. That is the challenging portion for a Web Designer to keep the consistency of design throughout the browser. This required pseudocode for vendor specific. Range Input can be horizontal or vertical. Here is an example of horizontal and vertical.
<input type="range" orient="vertical" />
input[type=range][orient=vertical] {
writing-mode: vertical-lr;
direction: rtl;
appearance: slider-vertical;
width: 16px;
vertical-align: bottom;
}
HTML Range Input is basically operated by either mouse or skin touch, is doing not allow typing, only drag and drop. This control works on both desktop, mobile and other devices. HTML Range Input has two parts. One is a Thumb and another is a Slider. Thumb moves onto Slider. In some browsers Thumb and Slider properties, if not adjusted properly, the design is distorted. Here is an example of the same.
So, the designing of the Input Range is very critical. Designers need to handle browser-specific pseudocodes for design for thumb and separate designs for range input and finally merge to create a single CSS. This requires a lot of time to design HTML Range input. This type of problem is a time-consuming matter. Sanjukta.com introduced the CSS Range Input Generator. This is a free and open-source tool to handle CSS generation for Range Input. Every day, thousands of designers create their own designs and happily place the CSS in their projects.
This tool allows creating CSS i, e Cascading Styles Sheet for HTML Range Input and downloading and copying the code. This tool is made of free software like JavaScript, Mysql etc. and open to all. This tool allows Live Preview when you are changing designs. You don't need to check again and again and open it with a browser to see your code and to test multiple browsers and to test multiple devices. The code will create a code which is all browser comparable and all device compatible.
| Browser | Engine | Prefix Used | Example Pseudo-Element |
