The main objective of this study is to examine the phenomenon, Structural change in the gross domestic product of Botswana and possible forecast and recommend for future adjustment. Gross fixed capital formation (% of GDP).

BFTSC was created to capture the trend, seasonal, cyclical and irregular components as automated combined image and to present them in a single plot. The result obtained, model acquired from the components (pattern) extracted using BFTSC was subsequently processed for forecasting purposes and recommendation follows. The real data findings suggested that BFTSC can provide a better time series components identification better than manual process and hence should be taken seriously. Botswana GDP is gradually declining; caution should be taken to improve the GDP such that Botswana can have bounty reserve and can also loan poor and financial weak countries. Improvement Botswana GDP is recommended.
