1. Introduction
• Software development organization are nowadays
looking for new ways to improve their performance.
• However, there is a proliferation of different
development methods working in different areas
and organizational levels:
 hard for industrial enterprises to link their strategic
business goals to appropriate improvement activities,
and for the researchers to combine prior work to steer
further relevant research
• Propose a holistic framework for systemic Lean
Software Enterprise research and development.

2. Related Work and
Foundations (1/2)
• Lean research inferences for software enterprises

LIMITATIONS for
Software Enterprises
Lean Enterprise
Thinking (Sect.
2.1)
 What is it that makes a
lean enterprise?
Lean Production
(2.2)
 How does production /
manufacturing operate
there?
Lean Product
Development (2.3)
Lean Software
Development (2.4)
Lean
Transformation
(2.5)
 How does new product
development join?
 How to emulate
physical production?
 How to conduct
programs of
organizational change?
 systemic valueorientation
 workforce-based
mindsetting (culture)
 JIT
 automation with a
“human touch”
(Jidoka)
 Set-Based Concurrent
Engineering
 flow and “wastes” in
software development
 continuous
improvement
(problems, excellence)
 concepts and terms of
‘Lean’ and ‘Agile’
currently not all exactly
defined
 material flows replaced
with knowledge flows
 equipment replaced
with knowledge work
 intangible nature of
software creation
 lack of solid underlying
reasoning and analysis
 no established
pathways for software
organizations to follow

• Lean methods, practices, and tools are
means to achieve those software
project goals. People use them.

3. Research Model
• On the other hand, there may be some
impediment factors preventing from
applying the means efficiently.
• Many interrelated factors are necessary
enablers for making all that happen
effectively in practice.

4. Empirical Studies
Case study research
instance (Figure 3):
Certain support observed:
• r1: There may be (observable) wastes
in successful software projects.
• r2: The Kanban method does not
eliminate all wastes.
• r3: People can identify (“see”) wastes
when questioned (retrospectively).

Some new propositions (for further study):

r3
People / Team
• p1: The Kanban method contributes
positively to project success.
• p2: Wastes hinder project performance
(value flow).
• p3: The Kanban method eliminates
(avoids) certain wastes.
• p4: People tend to favor the Kanban
process model.

5. Conclusions (1/2)
• Proposed a tentative framework for roadmapping
and conducting research and development on Lean
Software Enterprises:
•
not a prescribed universal model
•
product development and firm performance effects:
•
value flow
•
specific needs and performance goals of the company
•
operational R&D cycle:
•
enterprise modelling
•
effects

5. Conclusions (2/2)
• Future work:
•
What all different areas of business competence
should a Lean Software Enterprise model address at
each level?
•
Which particular realizations of different Lean Software
Enterprises require business- and technology-specific
implementations?
