Motivation - Software Development Scenario 1
Small software Developed alone As a passionate hobby For the own needs of the developer No major consequences of bugs No schedule pressure No limitations on effort usage Software will be maintained by nobody or the developer himself
Motivation - Software Development Scenario 2 Large software Developed by a team Developers’ daily work Used by many different users Software is done for a paying customer Every work hour costs money Management wants to follow the project Strict schedule and budget Bugs may cause serious consequences Maintained by others
What needs attention in this scenario?
Motivation - Software Development Scenario 2 Large software (complexity, architectural design) Developed by a team (communication, coordination, team spirit) Developers’ daily work (motivation) Used by many different users (understanding real needs) Software is done for a paying customer (accountability) Every work hour costs money (efficiency, prioritization) Management wants to follow the project (visibility, risks) Strict schedule and budget (predictability) Bugs may cause serious consequences (quality, proof of quality) Maintained by others (maintainability, documentation, training)
Course = Project Work
Groups of 7-9 students Real customers with real topics Duration about 5 months
23.9.2007 – 4.3.2008
Required effort 150h/person (6p) ~10-15h/week
Project Stakeholders
Project group students, who develop the software
Customer 1 or several persons from the customer organization provides the topic and requirements for the system to be built often can also help with technical issues takes the responsibility of the system after the project

Project Topics
Collected from TKK and industry
Lots of alternatives
Customers have prepared topics in advance
Software development projects secondary goals may include e.g. technology reviews
Project scope flexible
Project Topics – Legal Issues
Intellectual property rights (IPR) open source, or customer gets IPRs
Non-disclosure agreement (NDA) some companies require this
Contracts prepared by TKK lawyers
TKK <-> companies TKK <-> students
Public documentation except code and technical specs if the customer requires NDA she
must review documents before publication
Participation fee for industrial customers
commitment course costs
Registration and Forming of the Groups
Register to the course DL We 10.9. 13:00 (Tomorrow!)
Teacher selects the SE experts immediately after the DL
SE experts form trios register a trio by e-mail to the teacher immediately after Fr 12.9. 13:00, teacher forms trios of the remaining SE experts
SE expert trios recruite developers be quick! send e-mail to the teacher immediately when you recruite someone after Fr 19.9. 13:00 teacher assigns the remaining developers into groups
You can try to form a trio today here in T1
Project Topics – Selection Process
Customers present themselves and the topics Tu 16.9. 17:00-19
no contacting before that
SE expert trios apply for topics contact 2-4 customers “sell” your group to the customer
short CV of the group having good developers may help
Ensure the acceptability of the customer and the topic
her commitment to the project her understanding of the domain and
technologies her understanding of the course
context provided infrastructure expected skills from the group
Say “yes” quickly get confirmation from the customer say no to other customers immediately inform the teacher
If all the customers say “no” contact new customers
If you are not sure, try another customer.
Project Topics – Selection Recommendations
What do you want to learn? domain technology getting to know a certain customer’s organization
Too easy a topic? boring no ”bonus” points in the evaluation
Too demanding a topic? unsatisfied customer fulfilling customer’s goals may take too much focus away from other
educational goals of the course
Project Topics – Proposals

Other parties several teachers from SoberIT computer administrators from SoberIT Accenture
Software Process – Framework
Process framework provided iterative and incremental
phasing and schedule fixed enforces certain good work practices and crucial documents allows lots of freedom (and responsibility) for customization
Software Process – Special Challenges (1/2)
Project is done for an external customer understanding the true (and changing) needs-> requirements engineering during the whole project-> managing customer’s expectations
Physical distribution often no common workplace and time for project stakeholders-> special care for communication and project visibility
Temporal distribution only one of several on-going ”projects” for all participants long duration, but only 10-15h of effort a week-> you can’t keep everything in your head-> documentation overhead
Software Process – Special Challenges (2/2)
New team and organization no existing development culture (process) all members do not know each other-> process must be planned from scratch and communicated to everyone-> team spirit
Software will be maintained by other people after the delivery the group is not responsible for the system -> involving the customer’s technical people early-> knowledge transfer via training and documentation-> high code quality
Software Process - Iterations
Software Process – Project Control Variables
Quality ”fixed” high quality recommended some alleviations to carefully selected quality aspects are allowed if that is
what the customer really wants
Calendar time fixed project schedule defined by the course major control points such as iteration demos
Effort fixed 27h/credit/person
Scope flexible adjusted depending on the groups’ skills and knowledge of the problem domain
Software Process – Details
Lecture on the software process framework on 23.9. 16-19 minor changes to current materials may be done before that
Every student in any role should read all process framework materials in the beginning of the project
http://www.soberit.hut.fi/T-76.4115/08-09/instructions/process.html
Mentoring (1/2)
Purpose help the project succeed ensure enough focus on the educational goals
Meetings with the mentor in 3 mentor meetings in 3 iteration demos in 1-2 process reviews in some work sessions (customer meetings, code review etc.)
invitation from the group
Other forms of participation continuously observing the project
status reports, meeting memos, irc, … answering project related questions by e-mail evaluating the group in the end of iterations
points and comments
Mentoring (2/2)
Help the mentor help you! keep him up-to-date prepare for the mentor meetings invite him to some work sessions
increases visibility to work practices
Every project will face problems identify and solve them quickly ask help when needed
Mentor’s rough effort allocation per group ~1h for each meeting (*~9) ~4h for reading, grading and feedback in the end of each iteration (*3) ~3h/iteration (*3) for
observing the project answering e-mails preparing for mentor meeting
~30h TOTAL
Experience Exchange Sessions (EES)
Discussion on problems and good practices related to a certain SE theme project management, RE, QA, architecture
Participants 1-2 students per group, those who are responsible of the EES’s theme teacher and some guest experts
Students should propose topics 24h before each session practical problems and/or innovative solutions from your project
Teacher prepares an agenda each topic is introduced shortly by one proposer of the topic before discussion
Sending 2 proposals and participating to EES gives 0,5p to the group 8 sessions scheduled
3 for project managers, 3 for QA managers, and 2 for architects
Evaluation – General
Both the results and working methods are evaluated
Several evaluators customer
based on all available information mentor ensures the objectivity of customers’ evaluation
mentor based on all available information mentor adjust his scale in evaluation meetings with other mentors
group members may evaluate personal contribution of other group members
Evaluation – Course Grade
Points are given both during and after the project in the end of each iteration
Scale from points to grades is published in the end of the course
Filling the course feedback form by the given DL is mandatory
Evaluation – Iterations (Customer)
Focus on iteration’s results but working methods are
considered, too
Manage customer’s expectations in iteration planning
Evaluation – Iterations (Mentor)
Focus on work practices Conformance to the mandatory
practices plan and usage
Use of other good work practices Continuous process improvement Visibility of use
show them to the mentor avoid unnecessary documentation e.g.
invite the mentor to some work sessions
Scale 8 fulfills some requirements
with distinction and at most a couple of minor complaints
7 meets requirements and at most some minor complaints
6 at most a couple of major or some minor complaints
4-5 some major or lots of minor complaints
2-3 several major complaints 0-1 virtually no results
Evaluation – Project’s Results
Customer compares to the original/updated
project goals
Mentor compares to typical course
projects +/- a few points based on
project’s difficultymanage customer’s expectations in the beginning and during the project
Evaluation – Personal Contribution
Each group member may evaluate each other's contribution raises and deductions of +/-1 grade
the sum must be 0
Proposals can be sent privately to the mentor however, open discussion within the group is recommended
Mentor may change personal grades by +/-1 based on proposals
If the group gets enough points for grade 5, deductions are discarded.
