Which cost estimation method do you think is the most accurate? Why?
The accurateness of cost estimation process can make or break project success. We should know the strategies that will help us gain control of this key area and ensure future project profitability!
Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project.
The evidence on differences in estimation accuracy of different estimation approaches and models suggest that there is no "best approach" and that the relative accuracy of one approach or model in comparison to another depends strongly on the context. This implies that different organizations benefit from different estimation approaches.
One of the greatest challenges for any company is to successfully deliver on all aspects of a project both according to the client's specifications and within the allotted budget. It is often the case that either one aspect or the other can be accomplished, but not necessarily both. When it comes to controlling costs, it is a critical first step to make appropriate estimations at the outset of a project.
Most organizations use multiple methods for estimating projects. My preferred ones are parametric cost models and analogy. In the case of analogy, it is beneficial to consider the similarities between a previous system and the new system being estimated. This also provides an opportunity to explore the feasibility ...

Estimating Cost Functions for Blockbuster and Netflix

Assessment of cost function estimation methods by using the attached Netflix and Blockbuster Financial Data spreadsheet (attached) to develop cost function estimates for both Netflix and Blockbuster using the following methods:

- Account classification
- High-low
- Regression analysis methods

In regards to account classification, high-low, and regression analysis,Which method do you feel best estimates cost functions for both Netflix and Blockbuster? Why?

Which of Netflix's or Blockbuster's costs could be appropriately estimated using the account classification method? Why?

Which of Netflix's or Blockbuster's costs could be appropriately estimated using the high-low method? Why?

Which of Netflix's or Blockbuster's costs could be appropriately estimated using the regression analysis method? Why?

Are there any other methods of estimating cost functions other than the account classification, high-low, and regression analysis methods?

In general, which cost function estimation method is likely to be the best and why? Under what conditions is, or are, the best method(s) inappropriate?
