Gordmans is developing a mobile app to reach its target customers of mothers aged 25-49 with household incomes of $50,000-$100,000. The app will extend Gordmans' existing Oracle retail system to mobile using Oracle ADF, which supports both online and offline mobile apps. It has the potential to reach 19.5 million existing smartphone owners. The project timeline is 6 months and costs $538,000 initially but is expected to generate a net benefit of $4 million in the first year, with an 8.3% ROI and payback period of 12 months. It poses low risks and has a positive NPV and profitability index, indicating it is a good investment.
