IS2000 - Global analysis

Organisational factors

Organisational factor Flexibility and changeability Impact
O1: Management
O1.1: Build versus buy
There is a mild preference to build The organisation will consider buying if it is justified There is moderate impact on meeting the schedule
O1.2: Schedule versus functionality
Meeting schedule is preferable over delivering some features There is negotiability for several features There is a moderate impact on meeting the schedule and the first product release
O2: Staff skills
O2.1: Experience in building structured design
All in-house developers have these skills. n/a There is a small impact.
O2.2: Experience in object-oriented analysis and design
Half of the in-house developers have these skills It is feasible to hold training There is a moderate impact on achieving good design
O2.3: Experience in multi-threading
One in-house developer has this skill The subject area is too complex to rely on training There is a moderate impact on meeting performance
O2.4: Experience in building multi-purpose systems
Two in-house developers have this skill Training supplemented with software abstraction may alleviate lack of skills There is a large impact on meeting performance
O4: Development schedule
O4.1: Time to market
Time-to-market is 2 years There is no flexibility There is a large impact on design choices in all areas.
O4.2: Delivery of features
The features are prioritised These features are negotiable There is a moderate impact on meeting the schedule
O5: Development budget
O5.1: Head count
There are 12 developers We can hire 1 or 2 permanent or have a large number of contract developers There is a moderate impact on meeting schedule.

A study of these factor tables indicates:

  • There is no flexibility in time-to-market (Aggressive schedule)
  • Deficiency in skills in some areas (Skill deficiencies)

Technological factors


Product factors


Issues / Strategies

  • Aggressive schedule (slides 29-30, lecture 3)
    • Solution: Reuse software, buy COTS components and release low-priority features at a later stage.
  • Skill deficiencies (slides 31-32, lecture 3)
    • Solution: Avoid the use of multi-threading and encapsulate multi-process facilities.
  • Changes in software technology (slide 40, lecture 3)
    • Solution: Use standards where possible, and develop internal standards for COTS components.
  • Easy addition and removal of features (slide 47, lecture 3)
    • Solution: Use the principle of separation of concerns to develop specific strategies to address particular problems with features and the UI.
  • Easy addition and removal of acquisition procedures and processing algorithms (slides 17-20, lecture 4)
    • Solution: Define domain-specific abstractions to facilitate the task of implementing acquisition and processing applications.
  • Real-time acquisition performance (slide 21, lecture 4)
    • Solution: Partition the system into separate components for algorithms, communication and control to provide the flexibility to implement different strategies.
