May 21-23, 2018 2018 SESE TourOn Quest for the Grail: Implementing PLE in Large Organizations
AGENDA
The industrial context – A changing world
PLE & Reuse – The starting point
Barriers & Top challenges – Possible solutions
Organization, SE processes & practices… are they impacted?
Conclusion
6
May 21-23, 2018 2018 SESE TourA too familiar picture in all sectors…
Shorter times-to-market
Safer
Higher profits
More reliable
Highly competitive markets
More attractive
Global marketplace
More cost-effective
7
May 21-23, 2018 2018 SESE Tour… in a fast changing world
Significant changes over the past few years
New players – customers, providers, competitors
Market growth spread world-wide
Emerging societal needs & constraints
Accelerated evolution of technology
Key factor: delivering the appropriate product/service with ever shorter
times-to-market and at competitive costs

May 21-23, 2018 2018 SESE TourIn real life…
Problem statement: How can a large, global organization transition from a widespread,
careless practice on reuse to an effective and profitable implementation of PLE?
10
May 21-23, 2018 2018 SESE TourFirst difficulty: where to start
References for a reuse practice for
Reuse: a well
documented practice in
01 engineering complex systems is scarce
and relatively new
SW and manufacturing
02
04
Let common sense be the guide:
Understand where you are (identify
Apply a little systems thinking
current practices) & Decide where
you want to go (how would we like to
go about your business)
03 & start with your own needs

Conclusion
13
May 21-23, 2018 2018 SESE TourSecond difficulty: how to set people in motion
Acceptance and application of PLE principles is difficult in areas
where reuse is performed “unintentionally”
PLE calls for a more rigorous formalization
It is seen as burdensome, rigid & process-oriented
PLE requires upfront investment and forethought
Enterprise transformation
Keywords: Step-by-step & Flexibility
Best approach: a balance between your problem and your maturity
14
May 21-23, 2018 2018 SESE TourNot “one size fits all”
15
May 21-23, 2018 2018 SESE TourThe top challenges / barriers found in industry
“Reuse concerns only final Careless reuse
3 tangible products” 4 (Copy-paste is not engineering)
Cultural Change
2 “I want my product line, too!” Power to the Projects
1
(or Quick wins = long-term losses)
Organization, Governance
& Funding
16
May 21-23, 2018 2018 SESE TourSowing the seeds of PLE success
Anchor PLE in the business strategy of the Organization
Align Business stakes product policies / portfolio management / market
segmentations (customer value) product variability (features / standard
configurations) product architectures building blocks / technology
Formalize and share the purpose of PLE across the Organization
Think whole life cycle & cross-functional
Be transparent on required investments & expected benefits
Sponsorship, communication & people (training)
Far beyond an engineering issue
17
May 21-23, 2018 2018 SESE TourFormalizing reuse practices (framework)
18
May 21-23, 2018 2018 SESE TourMind the technical pre-requisites & enabling factors
Implement configuration Chose applicable variants and
& derivation mechanisms instantiate asset repositories
Explicit What engineering artifacts are
dependencies affected and how
The issues: defining core assets &
Describe product having one single point of truth
variability (not the choice of the language or the
modeling technique for variability)
Stop gambling 1. Use Systems Engineering
2. Perform good SE

24Conclusions
Cultural change Master your assets & focus your efforts
• Embarking into PLE is a long journey • Create reusable assets repositories
• Needs alignment between functions & • Promote the sharing of engineering
stakeholders and support from top assets across product lines / countries
management • Extend variability management across all
Put the company’s money in the disciplines/domains
right place
Mind the gap & the obstacles! Define optimum PL scopes
• IT and tool interoperability
Get more information OUT of tools than
!. • Define “inclusive” Product Lines
• Every single artifact managed as a
what is put INTO tools reusable asset?
• PLE often means a major shift from project • Do not aim at a perfectly stable planning
(single-system) to a more product-centric of variability
state of mind
Plan your PLE organizational transition strategy
