Running head: HOMEWORK 4
Chapter 7-Task 1
Assumptions
The addressed Software together with the internal software and parts of the software’s required
will cost about $5000 each that it totals to about 10000$. Software testing is also required since it
is estimated to cost about $2200 and the business plan to cost about 1100$.
Furthermore, the travel costs are also estimated at a total of $2500 in a trip. Both the hotel and
accommodation is also estimated to not exceed $1000 as the car hire is expected to be cost $500.
The estimated number of trips is 10 and is also designed to ensure that the groups receive regular
updates with anything needed in face to face events organized.

Task 2
Chapter 7-Task 3
Chapter 7 – Task 3: - Assume that you have completed three months of the project. The
BAC was$130,000 for this six-month project. You can also make the following assumptions:
PV = $60,000 EV = $55,000 AC = $50,000
a.
What is the cost variance, schedule variance, cost performance index (CPI), and schedule
performance index (SPI) for the project?
Planned value=$60,000
Earned value=$55,000
Actual cost=$50,000
Cost variance =CV=EV-AC
CV=$55000-50000=$5000

HOMEWORK 4
Schedule variance= SV=EV-PV
SV=55,000-$60,000=-$5000
Cost performance index (CPI) = CPI=EV/AC
CPI=$55,000/$50,000=1.1
Schedule performance index (SPI): SPI=EV/PV
SPI=$55,000/$60,000=0.92
b.
How is the project doing? Is it ahead of schedule or behind schedule? Is it under budget
or over budget?
The project I will costs$50,000. This project is $5000 behind schedule and it under
budget by $5000.
c.
Use the CPI to calculate the estimate at completion (EAC) for this project. Is the project
performing better or worse than planned?
Estimate at completion (EAC)
Estimate to complete (ETC)
Cost performance index (CPI) = CPI=EV/AC
CPI=$55,000/$50,000=1.1
Estimate to complete (ETC) = (BAC-EV)/CPI
($120000-55000)/1.1 = 59,090.91
Estimate at completion (EAC) = AC+ETC
EAC=50000+59090.91=109090.91

d.
Use the SPI to estimate how long it will take to finish this project.
Schedule performance index (SPI) = SPI=EV/PV
SPI
55000/60000=0.917
Estimate time to complete = Original time estimate/Schedule performance index
= 6/SPI
= 6/0.917
= 6.543
= 6-6.543=-0.543
The project was schedule for completion in 6 months but will overrun by 0.543
month.

Explanation
Simplicity
The website appearance is largely regarded as the most important
aspect and the piece of information rendered needs to be found by
the users easily. Additionally, the website must be effectively
designed as simple as possible and to be understood by the
individual users without any difficult experience.

Conversion Optimized
The required content will be availed in English for various websites
5
HOMEWORK 4
as the global treps website must be equally available for all kinds of
persons. Moreover, the conversion of the message mostly relies on
the destination together with the content to be converted into other
languages on the basis of the requirement to the users.
Accessibility
The persons who mostly lack experience in browsing and those
with disabilities in equal measure must have the ability to use the
website with the main goal of this website creation.
Chatbot
The visitors to the web can interact with the chatbot and
conversationally, the interaction will be affected. The different
forms of queries of the visitors can be clarified through interacting
with the chatbot and for every query by the visitor, the response
will be programmed as expected.
Downtime
The website should not exhibit any down time since it needs to be
frequently available to individual users. Website loading should be
quickly performed.
Chapter 8-Task 2
Feature
Measurement
Simplicity
The website is also designed as simple and every individual can
effectively understand the features of the website. Hence, the
registration of people can be effectively conducted easily
without difficulties due its simplicity.
Accessibility
The exhibited website can be accessed by people with
disabilities as well and by most people who are not having any
6
HOMEWORK 4
browsing experiences. It is also successful as there are over two
registrations from the disabled persons.
Chatbot
The existence of the Chabot is mostly conducted by many
individuals and most people seem to clarify their queries with
such application.
Downtime
The website downtime is perceived as low and many people
visit the website each day. There further exists many successful
registrations on daily basis and the downtime of the website is
not largely affecting the visitors in the website.
Conversion Optimized
The different features of the conversion and optimization
process seem significantly helpful for the user and it is also
remains useful to undergraduates. There also exist about over 8
successful registrations by such undergraduates every day and
the feature seems helpful to such people.
