In particular:
  +
* Every component apart from class and lab participation carries up to 30% extra credit.
  +
* Class and lab participation involve class and lab attendance. You can skip up to 4 classes and up to 4 labs without any justification -- please notice that the number do not sum up, meaning that this does not mean that you can skip 5 classes if you skip only 3 labs. However, if you skip more than 4 classes or more than 4 labs you are required to have a justification approved by DoE for all your missed classes or missed lab, including the first 4, otherwise you will fail this component of the course and consequently the entire course.
  +
* Students aiming for a C, have only to pass Class and lab participation and the intermediate mini-oral (after week 2).
  +
* Students aiming for a B also have to sustain the final oral exam.
  +
* Students aiming for an A also have to do the project.
  +
* Failing any attempted component of the course implies failing the entire course and go to the retake.
  +
* The final grade is computed summing the points taken in each part and considering the table above, so it could be that, for instance, a student aiming for an A but not getting enough points in each of the component would then get a C or a B.
   
  +
For this reason it is strongly recommended that each student, based on her/his desire, load, condition, etc decides at the beginning of the course which grade to aim at.
−
</div>
  
−
Each component apart from the weekly tests will be assessed on a scale 0-10, where 6 is the minimum passing grade. In case of exceptional work a 10 cum laude will be assigned, with a numeric value from 11 to 13 at discretion of the instructor. The homeworks will be initially graded on a scale 0-2 weekly and then the overall grade will be assembled on a scale 0-10.<br />

The grading, though, is not a simple linear combination of the components above. In particular:
  
   
  +
=== Recommendations for students on how to succeed in the course ===
−
* failing any part of the evaluation will trigger a failure in the entire course,
  
  +
The goal of the project is to read the book and understand what is the takeaway for software engineering, considering three fundamental aspects: a) the process to follow, b) the product being built c) the structure of the team and its organization. The projects will be executed in weekly iteration on traceable files.
−
* the weekly quizzes will be averaged on the (n-4) best performances, where the 4 will be used to consider any kind of absence of the student, without requiring any additional documentation; if the student has legitimate reasons to be absent more than 4 times, then supporting document should be provided for all her/his absences,
  
−
* if there are not failing components, the final grade will be computed as a weighted average of the components above approximated at the highest second digit and then rounded to the closest integer.
  
   
  +
The projects will be partially graded weekly (30%) and part at the end (70%). Moreover, at the end you will need to give a 5-minute presentation of your work.
−
Note that the questions for the exam are taken from the textbook.
  
   
  +
During beginning of the project you will create the overall GQM of the project and you will be initially evaluated based on it. After setting the GQM, you will also create the vision of your project with a roadmap. Based on the roadmap, you will start to have the reviews of your project increments in terms of the a) progresses toward the completion b) accurate planning based on the defined GQM, and c) quality of the work. Weekly grade ranges from 0 to 2 points.

Intended Learning Outcomes (ILOs)

What is the main purpose of this course?

This course exposes the student to the core concepts behind Lean Development in Software Engineering, beyond myths and legends, emphasizing how it relates to the general principles of Lean Development. It discusses the different possible software processes, how they can be tailored, enacted, and measured. In addition, a significant part of the course is centered around the application of lean to software development to knowledge intensive areas not necessarily connected to software.

ILOs defined at three levels

Level 1: What concepts should a student know/remember/explain?

By the end of the course, the students should be able to ...

  • creative nature of software production as an act of creativity of the human mind,
  • the substantial differences between tame and wicked problems,
  • the core concepts of measurement in software engineering,
  • the fundamentals of Taylorist/Fordist approaches to (software) production,
  • the basis of lean and agile software development,
  • the “dark” side of agility,
  • the importance of knowledge and knowledge sharing in producing software,
  • how to create an ad-hoc process for a development organization.

Level 2: What basic practical skills should a student be able to perform?

By the end of the course, the students should be able to ...

  • when a problem is “easy to solve” provided enough effort is put to such solution and when it is not,
  • what is a measure in general,
  • why it is important and how we can define and perform measurements in software engineering, especially in lean and agile development environments,
  • how to organize the development process to collect metrics non invasively,
  • the difference between pulling and pushing in (software) development,
  • the fundamental principle of agility,
  • the risk intrinsic in the dark side of agile,
  • how to organize an agile development process based on the definition of overall Goals, associated Question, and milestones based on Metrics,
  • an environment based on experience, like the Experience Factory.

Level 3: What complex comprehensive skills should a student be able to apply in real-life scenarios?

By the end of the course, the students should be able to ...

  • Compute the fundamental software metrics to track the evolution of a project,
  • Organize the aims of a (software) development organization in terms of Goals, Questions, and Metrics,
  • Create a tailored (lean and agile) development process for an organization producing software,
  • Define a path to insert and manage such (lean and agile) development process into an organization producing software,
  • Structure the experience gathering during inside an organization to based on it the future strategic decision of such organization,
  • Relate the various proposals for Agile Methods to the overall principles of Lean Management,
  • Define a suitable (lean) process for a new organization, a process to introduce and institutionalize it, and an approach to measure the outcome of such introduction and institutionalization.

Course activities and grading breakdown

Activity Type Percentage of the overall course grade
Class and lab participation (including class quizzes) 25
Intermediate mini-oral 25
Final Oral Exam 25
Project 25

In particular:

  • Every component apart from class and lab participation carries up to 30% extra credit.
  • Class and lab participation involve class and lab attendance. You can skip up to 4 classes and up to 4 labs without any justification -- please notice that the number do not sum up, meaning that this does not mean that you can skip 5 classes if you skip only 3 labs. However, if you skip more than 4 classes or more than 4 labs you are required to have a justification approved by DoE for all your missed classes or missed lab, including the first 4, otherwise you will fail this component of the course and consequently the entire course.
  • Students aiming for a C, have only to pass Class and lab participation and the intermediate mini-oral (after week 2).
  • Students aiming for a B also have to sustain the final oral exam.
  • Students aiming for an A also have to do the project.
  • Failing any attempted component of the course implies failing the entire course and go to the retake.
  • The final grade is computed summing the points taken in each part and considering the table above, so it could be that, for instance, a student aiming for an A but not getting enough points in each of the component would then get a C or a B.

For this reason it is strongly recommended that each student, based on her/his desire, load, condition, etc decides at the beginning of the course which grade to aim at.

Recommendations for students on how to succeed in the course

The goal of the project is to read the book and understand what is the takeaway for software engineering, considering three fundamental aspects: a) the process to follow, b) the product being built c) the structure of the team and its organization. The projects will be executed in weekly iteration on traceable files.

The projects will be partially graded weekly (30%) and part at the end (70%). Moreover, at the end you will need to give a 5-minute presentation of your work.

During beginning of the project you will create the overall GQM of the project and you will be initially evaluated based on it. After setting the GQM, you will also create the vision of your project with a roadmap. Based on the roadmap, you will start to have the reviews of your project increments in terms of the a) progresses toward the completion b) accurate planning based on the defined GQM, and c) quality of the work. Weekly grade ranges from 0 to 2 points.

The overall project success will be evaluated as following:
