Phases of web development

The process of developing web application and websites which works using the internet is known as web development. Web developers need to use scripting languages at both the server and client end. A content management system is necessary to create a static website (one page) to a full-blown web application. Website development includes the coding of the application logic, designing the user interface, incorporation of database and managing the user queries, hosting the website on the server, and maintaining and updating the website.

Question

### Project Activity Analysis

A project has been structured to include the following list of activities along with their required times for completion:

| Activity No. | Activity | Time (weeks) | Immediate Predecessors |
|--------------|----------------------|--------------|------------------------|
| 1 | Collect requirements | 2 | - |
| 2 | Analyze processes | 3 | 1 |
| 3 | Analyze data | 2 | 1 |
| 4 | Design processes | 4 | 2, 3 |
| 5 | Design data | 3 | 2, 3 |
| 6 | Design reports | 2 | 4, 5 |
| 7 | Design documents | 5 | 4, 5 |
| 8 | Prepare final document| 1 | 6, 7 |
| 9 | - | | |

#### Instructions:
a. **Draw a network diagram for the activities.**
- Create a graphical representation showing the sequence of activities and their dependencies.

b. **Calculate the earliest expected completion time.**
- Determine the minimum time required to complete the project by analyzing the paths in the network diagram.

c. **Show the critical path.**
- Identify the longest path through the network diagram, which determines the project's shortest possible duration.

d. **Evaluate the impact if activity 6 were revised to take six weeks instead of two weeks.**
- Assess how increasing the duration of activity 6 affects the overall project timeline and the critical path.

#### Graphical Explanation:
The image provides a tabulated list of project activities, necessary for constructing a project management network diagram. Each activity is assigned a time duration (in weeks) and depends on one or more preceding activities.

- A network diagram or flowchart helps visualize the order of activities.
- Calculations on the diagram show paths to estimate the earliest completion time.
- The critical path highlights the sequence with no flexibility in timing, directly influencing project completion.

In addressing the given tasks:
- Drawing and analyzing the network diagram includes creating nodes (for activities) connected by arrows depicting dependencies.
- Calculating the earliest completion involves summing the durations along different paths and identifying the longest one.
- Revising activity 6's duration requires updating the network diagram and

This is a project description to develop a "course registration system". At the beginning of each semester, students get a course catalogue containing a list of course offered along with required information such as professor, department, and prerequisites. The system will allow students to select four course offerings for the coming semester. •Professors will be able to access the online system to indicate which courses they will be teaching. They will also need to see which students signed up for their course offerings.
