Introduction
Today’s products have many advanced features enabled through the use of
software-driven electronics. Automobiles have advanced safety features, automatic
controls and service diagnostics. Home appliances have software-powered
controls designed to provide automated features and energy saving controls.
In order to compete, Manufacturers need to be able to synchronize all aspects of
complex product and process design, pushing all systems engineering and design
issues to the front of the process whenever possible. They must optimize product
performance, integration and quality by unifying interdependent mechanical,
electrical and software subsystems – many of which may be designed and built
by suppliers.
Developing these embedded products involves a set of challenges in coordinating
the disparate engineering disciplines on a single design.
All the above results in products with complex multi-disciplinary design, increased
product data and information to be managed and shared in an organized,
centralized and real-time manner across an extended enterprise.
Hence organizations are in need for a system that can address the rising complexity
of products, need to collaborate real-time, manage product information in a
centralized location and yet make it available to different functional groups of
users across the geography.
Product lifecycle management, or PLM, solutions can provide an ideal
framework for implementing enterprise-wide new product development goals.
Organizations have increasingly realized the need for PLM systems and have also
implemented them.
Embedded product development life cycle
New product development life cycle for embedded products typically involves
the following important phases – Concept, Requirement, Design, Embedded
software development, Mechanical development, Hardware schematics/board
layout, Prototyping, Hardware Software integration, Verification and Validation
(VV), Electronic packaging and may be system integration, Compliance
pre-scanning, System testing, Manufacturing transition, Production and
Support/ retire.

New product development cycle and key functional areas for a typical
embedded product
Typical challenges in Embedded Product
Development Life Cycle
Embedded product development is a difficult proposition: bring together multiple
highly complicated disciplines with little understanding or visibility into their
companion areas. Following listing provides the list of some of the challenges in
the embedded product development life cycle.
Product complexity: Developing embedded software is complex as it involves
interfacing with various sub-system with real time requirements and with minimal
resources to accomplish the same. Ensuring all design requirements are met in
the final system requires close track of requirements across various disciplines.
In addition, it is very difficult to understand the impact of design change across
disciplines.
Isolated functional teams: Software development teams are not integrated
with electronic and mechanical design teams. Early identification of system level
problems is very difficult because of the isolated teams.
Too many product variants: Products are increasingly differentiated on the
basis of their embedded software features.
Distributed design groups: It is difficult to manage the growing number of
distributed design setups. Geographically distributed design teams often face
issues in accessing right information during the product development.
Compatibility: Development teams find it hard to identify which hardware/
software modules are compatible. It is very difficult to identify and manage huge
number of software enhancements/upgrades over a period of time in the case of
longer product life cycles, typically medical, automotive, aerospace and defence.

Unavailability of experienced system engineers: Difficulty in finding and
hiring experienced system engineers/lack of cross functional knowledge
Difficulty predicting product behaviour: Difficulty predicting / modelling
system product behaviour until physical prototypes exists. Understanding the
interdependencies of the software design with other cross functional designs is
often late-stage process conducted only after the software is uploaded to the first
prototype.
● Debugging software problems and issues are not easy in a real
time environment
● Hardware resources like memory (RAM, ROM), processor bandwidth etc re-
quired to accomplish the product development are not abundant and have to
accomplish product with less RAM/ROM. This is not the case in a PC based
software development
● Since the target platform where the embedded software executes is different,
than in software that executes on a PC, debugging is difficult and requires use
of good debugging tools
● When an issue/problem surfaces, generally it is very difficult to find if
it is due to hardware or software etc or is it combinational? This poses
great challenges
● Embedded product generally requires interfacing with multiple systems and
these systems are not readily available during development requiring use of
simulated environment during early phases. If these environments are not
exactly identical to the final environment, considerable challenges faced
during final testing
Software development is often outsourced, but system integration is still the
responsibility of the OEM engineering group
Software lifecycle issues increase today’s service and repair costs
What is PLM?
Product Lifecycle Management (PLM) is a strategic business approach that
applies a set of business solutions in support of the collaborative creation,
management, dissemination, and use of product records across the extended
enterprise spanning from product concept to end of life.
Product Life Cycle Management Solutions provides the enterprises with a
rich environment for the collaborative development of mechanical, electrical,
electronic and embedded software technologies in a single source of product
and process knowledge. PLM helps to establish a common data model across the
engineering domains facilitating individual development teams can retain their
mechanical, electrical, electronic or software focus, while working in-context and

How PLM can help in addressing the chal-
lenges in Embedded Product Development?
The following processes or features help in collaborative design across multiple
functional teams geographically distributed and right product at first time during
the new product development life cycle.
Single source of product and process knowledge
PLM solutions combine existing business systems (Enterprise Resource Planning,
Computer Aided Design, Supply Chain Management, Document Management
Systems, etc.), providing a single source for product information including Bill
of Material (BOM) and supporting collaboration and communication within a
project environment.
It integrates multi-seat and multi-disciplinary design workgroups into a single
environment. It allows concurrent design and design re-use as well as product
visualisation for the entire enterprise.

PLM offers vaulting, versioning control, check-in/check-out and security
protection capabilities enable the enterprise to manage and control this aggregate
knowledge in PLM global repository.
Global Collaborative platform
PLM provides a framework enables associative product development across
multiple functional teams. It also provide seamless collaborative design
environment in case of geographically distributed design groups.
PLM also enables product teams to work with their suppliers, allied partners
and trusted customers in a real-time environment that facilitates the rapid
formation of sourcing teams, concept studies, program reviews, design reviews
and engineering change processes.
Manage software binaries as parts
PLM provides integration with software development tools, e.g. IBM ClearCase,
Rational Rose, etc, ability to manage software binaries/builds as parts and the
appropriate links to the mechanical and electronic component configuration
are established.
Changes to software (and the associated electronic and mechanical equipment)
under configuration control must be approved before being incorporated. This
enables designers, developers, manufacturing, and service personnel to access the
product information and see the complete definition at any point in time. It also
ensures that they work with (and don’t violate) the correct configuration of the
version upon which they are working.
Workflow and CMII compliant Change Management
CMII (Configuration Management II) is a revolutionary business model, which
has replaced traditional change management strategies all over the world. CMII
provides a business process infrastructure that enables Project Management and
Quality Assurance to perform their tasks reliably and efficiently.
PLM tools provide workflow capabilities that enable review and release processes
for enterprise data like parts, documents etc.
PLM enables the organizations to implement change management at an enterprise
level and also ensures that downstream agencies, internal and external partners
and suppliers are fully integrated in this process.
Efficient Product Configurations Management
PLM provides the product structure, BOM views, alternates and substitutes,
effectivities and configuration management functionalities. In addition, it enables
the product development teams to integrate information generated by multiple
applications and create higher level product representations (such as product
models, product definitions, product configurations, and virtual prototypes).
