This study addresses the topic of continuous planning in the agile and lean software development context. The paper investigates how software companies can achieve various benefits by dividing their product development practices along the three horizons of growth. This approach allows software companies to have different product development and planning practices inside the company, thereby strengthening their positions in well-established businesses as well as creating growth in completely new businesses. Theoretically, the paper draws on the business literature of the three horizon model and on the literature of agile and lean software development. The empirical part is based on a case study with a leading Finnish software company. Altogether, 12 narrative interviews were conducted, involving people with various roles from product manager to chief strategy officer. The research presents a new approach towards continuous planning within multiple business horizons, to address common challenges in managing software product portfolios in different maturity phases.
