The growth of applications developed with the support of model transformations makes reuse a required practice, specially when applied to transformation assets (e.g. transformation chains, algorithms, and configuration files). In order to promote reuse one must consider the different implementations, communalities, and variants among these assets. In this domain, a couple techniques have been used as solutions to adapt reusable assets for specific needs. However, so far, no work has discussed their combined use in real software projects. In this paper, we present a new tool named WCT, which can be used to adapt transformation assets. Moreover, through lessons learned in industry, we address some reuse techniques devoted to adapt these assets.
