Study Notes
Multiple-Feedback Band-Pass Filter
- A multiple-feedback band-pass filter has two feedback paths through R2 and C1.
- R1 and C1 provide a low-pass response, while R2 and C2 provide a high-pass response.
- The maximum gain, A0, occurs at the center frequency.
- Typically, Q values are less than 10 in this type of filter.
Project Breakdown and Scheduling
- Projects can be broken down into tasks that should take about a week or two to complete.
- Bar charts are commonly used to represent project schedules.
- Task duration, effort, and dependencies should be considered when creating a project schedule.
Estimation Techniques
- There are two types of estimation techniques: experience-based and algorithmic cost modeling.
- Experience-based techniques rely on a manager's experience of past projects and the application domain.
- Algorithmic cost modeling uses a formulaic approach to compute project effort based on product attributes.
Cost Estimate Uncertainty and Contractual Terms
- Organizations may increase their price by a contingency to account for cost estimate uncertainty.
- Contractual terms can affect the price charged, such as retaining ownership of the source code.
Project Plan Sections
- A project plan typically includes sections such as introduction, project organization, risk analysis, and hardware and software resource requirements.
- The work breakdown section sets out the project activities, inputs, and outputs.
- The project schedule shows dependencies between activities, estimated times, and resource allocation.
Software Pricing
- Software pricing estimates consider hardware, software, travel, training, and effort costs.
- There is no simple relationship between development cost and price charged to the customer.
- Broader organizational, economic, political, and business considerations influence the price charged.
Factors Affecting Software Pricing
- Requirements volatility, financial health, and market opportunity are factors that affect software pricing.
- Organizations may lower their price due to requirements volatility, financial difficulties, or to gain market opportunity.
- Cash flow is more important than profit in difficult economic times.
