SECOND-GENERATION PARADIGM


Product Line Management Figure 1


Second-generation product line management (2G PLM) introduces a new factory model, whereby products are created from feature profiles and an automated product line factory, generating all variants of products and programs from a consolidated set of core assets.

across development and sustainment,” said COL Mike Flanagan, PM TRADE.


The LT2 product line architecture, stan- dards, assets, and environment have been used by more than 16 major Army and DoD live training programs, with more than 130 systems fielded. (See “Support- ing the Warfighter.”)


Second Generation Product Line Engineer- ing (2G PLE) techniques will ensure that the PM TRADE software product line strategy maintains the combat edge and builds resilience in our forces by provid- ing state-of-the-art training systems using a Consolidated Product Line Manage- ment (CPM) paradigm. This enables an automated production line process that optimizes productivity


and cost,


nates duplication and divergence, and provides scalable and efficient means of production. With CPM/2G PLE, the


112


Army live training domain has made an investment in an advanced product line systems engineering capability and is reap- ing substantial benefit.


SUCCESS BRINGS CHALLENGES This widespread usage of LT2 products presented challenging repercussions. The first-generation software product line reduced stovepipe development and the initial cost of developing new products in the LT2 family. However, with


this product-centric an issue as perspective


and increasing demand, managing the multiple customer variations could have become


the portfo- elimi-


lio continued to evolve. Product teams could pull individual components and add features unique to their individ- ual solutions.


With each new baseline created, cost and effort would begin to grow


the


exponentially for merging software fea- tures and patches from the products back into the core assets and then out to other members of the product line.


“We recognized early on that as the num- ber of


successful deployments in the


LT2 product line grew, the associated exponential


growth in cost and com-


plexity for maintaining the integrity of the product line would become difficult to manage,” said Mike Dillon, CTIA Project Director. “To optimize produc- tivity and cost, we needed to eliminate duplication, divergence, and the resulting merging. Our most effective way ahead would be to implement a product line approach that provides scalable and effi- cient means of production.”


With these challenges identified, PM


TRADE is implementing Second Genera- tion Software Product Line Management
