A computer-implemented method for generating a risk assessment regarding a software implementation project includes accessing a previously specified importance value and maximum score for each of a multiple of risk factors. The importance value for each risk factor reflects experience of an implementing entity regarding the extent to which the factor may negatively impact a software implementation project if the factor is not adequately addressed, the importance value and maximum score for each factor being multiplied to define a potential weighted score for the factor. An actual score for a particular software implementation project is received for each factor based on an analysis specific to the particular project. An actual weighted score for the particular project is generated for each factor by multiplying the importance value and actual score for the factor, and a relationship between the potential weighted score and actual weighted score for each factor. A risk level for the particular project is assigned to each factor according to the relationship between the potential weighted score and the actual weighted score for the factor. The risk level for each factor represents an assessment regarding the extent to which the factor may negatively impact the particular project if the factor is not adequately addressed. A risk assessment is generated for the particular project including one or more of the assigned risk levels for the particular project for one or more corresponding factors.

An automatic focusing imaging module comprises an imaging lens, an image sensor aligned to the optical axis of the imaging lens, a color separating processor, a controller and a shape memory alloy driver. Light passes through the imaging lens to be imaged on the image sensor. The color separating processor expresses an image sensed by the image sensor through three-primary colors respectively. The controller carries out MTF calculation on the image sensed by the image sensor, and current shooting object distance is determined according to a calculating result. When the current shooting object distance is larger than a preset standard value, the controller conducts defocusing fuzzy modification on the image sensed by the image sensor. When the shooting object distance is smaller than the preset standard value, the controller controls the shape memory alloy driver to drive the imaging lens to focus. The automatic focusing imaging module can obtain an image which is clearly focused no matter whether the object distance is larger than the preset standard value or not.
