Research Practice of the Scale Estimation Method Based on NESMA

Based on the common software scale estimation method, various functional point estimation method and NESMA, a scale estimation method suitable for space embedded software is proposed. By tailoring the estimation process, adding non-functional demand impact factor and fixed complexity weights, reduce the influence of individual subjective factors on estimation accuracy, and estimate the estimated workload of space embedded software as less than 15% different from the actual development workload of space embedded software in the space field.
