Process impact: The statement of
user needs documents and explains the actual desires of stakeholders
in roughly their own words. What they
desire is never exactly
what the product
provides. Documenting user needs here,
independently from the
SRS, helps to keep the
SRS precise and makes the tasks of verification and validation more
effective. This document is
not an informal draft of the
SRS, it is different document with a complementary purpose.
Agreed Goals
TODO: Has there been a clear statement of the overall goal of this
project that the stakeholders agree to? If so, paste it here or add
a hyperlink. If not, you should summarize your understanding of the
project goals into a brief statement and try to get the stakeholders
to agree to it. The text below gives three alternative examples,
select one, or write your own.
We were given an initial project
description that is agreed to by all stakeholders.
After several interviews and brainstorming
sessions, we have revised project description that
has been agreed to by all stakeholders.
There are still a few different (but overlapping)
visions of what this project needs to achieve. When a single joint
vision is agreed to, it will be hyper-linked from here.
Environment
TODO: Briefly describe various aspects of the environment where the
software will be used. Describe the environment as it is or
will be, not what you would wish it to become. The text
below gives a few examples.
- What is the system's business environment?
- Each real estate agent works with a set of
potential buyers and sellers. Real estate agents do not share
customer data with other agents, because they do not want to share
commissions. Information on specific available homes changes daily,
and this tool must help them keep up.
- Game players may visit several free web sites to
find information about teams or "clans". There is usually more
information available than they would choose to read, the challenge
is in having the most fun with the least effort. This website must
be familiar to players who have used other sites, but it must also
be better.
- What is the system's physical environment?
- This system is a web server that will run on a
machine in a co-located data center with 24x7 monitoring, UPS,
air-conditioning, etc. Users of this system are typically at their
offices.
- This application runs on hand-held devices that
will often be used while the user is walking from one section of the
warehouse to another. Lighting is good in that environment, but
there are many noises and distractions.
- What is the system's technology environment (hardware and software)?
- 60% of game players have machines with P-II or
equivalent processors, while 30% have P-I machines, and 10% have
less powerful machines. While many users have 17-inch monitors,
15-inch monitors or laptops with 1024x768 resolution are also
common.
- 65% of game players are using Windows 98 or
Me. 30% are using NT, 2000, or XP. The remaining 5% use Mac OS X,
Mac OS 9, or Linux.
Stakeholders / Actors
TODO: List and describe the stakeholders for this product. These
can be named individuals or roles that people play. For each
stakeholder, list/rank their key needs. Consider the expected
technical expertise of the stakeholders and how often they are
likely to use the system, as well as key strengths, weaknesses,
preferences, or other characteristics. Use a greater-than sign to
indicate inheritance among types of actors.
TIP: To get information on types of users, you can talk to actual
users. You may also want to talk to user surrogates (people who
work with users), such as domain experts, technical trainers,
technical support staff, technical writers, supervisors of users,
and your own sales and marketing department. You can find clues in
manuals and marketing materials for competing products.
- All
- All stakeholders share the following key needs:
- Security against abuses by other site visitors
- Convenient access to the site any time over the Internet
- Player
- Players want to have fun. That means a sense of discovery,
challenge, satisfaction, and community. Some players who become
involved in clans will spend a few hours a week, while others will
spend over 20 hours a week. So, they need new content posted often
to keep them interested. Players involved in clans are often power
users and have high expectations for the functionality and quality
of the site, but they may not have much knowledge of computer
science.
Key needs:
- Easily find information about clans
- Keep in touch with members of his/her own clan
- Understand the date and time of tournament play
- Easily report cheaters
- Player > Advanced player
- Advanced players seek more challenges to continue the sense of
discovery. They tend to play over 20 hours a week. They have seen
more of the game details, now the need to see the "big picture".
Key needs:
- View metrics that compare multiple clans
- Understand relationships between clans
- Understand overall schedule of tournaments

Notes from Interviews and Brainstorming
TODO: Keep a log of your requirements gathering. Paste in notes
from any face-to-face or telephone conversations with stakeholders
or from brainstorming sessions with members of the development team.
If the communication took place via email, link to it in the archive
or paste it here.

User Stories
TODO: Write brief user stories to explain how various actors would
interact with the system (directly and indirectly) to accomplish a
real-world goal. User stories are not use cases: user
stories are brief (3-5 sentences) paragraphs that describe one
specific scenario in concrete terms. In this description of user
needs, do not make assumptions about details of the system, instead
focus on the users. Note the source of each user story.
- invited-to-join
- John has gotten pretty good at SuperShooter by
playing on public servers about 8 hours a week for the last 3 weeks.
John has chatted with Bob about strategies and they have enjoyed
some duels. Bob is a member of the RedDawn clan. That clan plays a
tournament on a private server Friday nights. Bob invites John to
visit the RedDawn website and join. (Source: INTERVIEWEE)
- finding-the-tournament
- Bob is visiting his friend. He tries to use his
friend's computer to log onto the RedDawn SuperShooter tournament.
But, he does not remember the exact name of the server. So, he
visits the RedDawn clan website to find that information. (Source:

Performance and Capacity Needs
TODO: Briefly list the stakeholders' desired values for various
aspects of the system capacity. If you have a good idea about
averages or rates of increase, note that as well.
By the end of the first year of service, we should to reach the
following system capacity:
- 50,000 user records in the clan website account database (rate:
50-500 new registrations each day)
- 1000 users browsing the web site any given time
- 1000 gaming clans
- 1000 members of a single clan (average: 8)
- 4 MB max disk space for each clan (average: 0.5 MB)
- 100 game vendors posting advertisements on the site
- 1000 actual advertisements in the database
