Short answer
MadeByCat ran the UX/UI work and website renewal for ERN Holding, ERN Taahhüt and ERN Enerji as a single program: three sites delivered simultaneously on MadeByCat CMS under one program and project management, and launched together. ERN Batıyakası followed later as a separate project. The sites went live in 2026.
Client context
01ERN Group brings together businesses across energy, construction and real estate.
Business challenge
02The ERN Holding, ERN Taahhüt and ERN Enerji websites were to be renewed at the same time, as one program rather than three separate projects.
MadeByCat role
03UX/UI work and website renewal for ERN Holding, ERN Taahhüt and ERN Enerji, delivered on MadeByCat CMS under one program and project management; ERN Batıyakası delivered later as a separate project.
One program, three simultaneous launches
04ERN Holding, ERN Taahhüt and ERN Enerji were not treated as three separate jobs. They ran in parallel under one program and project management, with shared decisions taken once, and went live together.
UX/UI across group and company level
05The UX/UI work for the ERN Holding, ERN Taahhüt and ERN Enerji websites was carried out by MadeByCat, within the same program as the site renewals.
MadeByCat CMS
06All three renewed sites were delivered on MadeByCat CMS, as part of the same program.
ERN Batıyakası — a separate follow-on project
07ERN Batıyakası was taken on later as its own project and brought to life separately from the three-site program.
Solution
08Renewed ERN Holding, ERN Taahhüt and ERN Enerji websites launched together on MadeByCat CMS, with ERN Batıyakası delivered later as a separate project.
