Three strategies: overall cost leadership (being cheaper), differentiation (offering something better, ideally even unique), and focus. e-commerce: different forms (completely electronic (pure digital), or mixed e.g. "clicks and bricks"), or physical product (bricks and mortar). types (B2B, B2C, etc.),  B2B (Business to Business): 85% of e-commerce volume, uses various mechanisms  B2C (Business to Consumer): smaller, but more complex  C2C (e.g. trademe, eBay)  B2E (E=Employee)  E-Government - can be G2B or G2C (C=Citizen)  E-Business: broader, also encompasses non-selling activities (e.g. collaboration, service, and internal transactions) benefits,  International markets more accessible  Can lower costs e.g. processing orders, no physical presence  Customers get larger choice and 24/7 access issues.     

International reach ... but still complexities around e.g. taxes, importing Channel conflict: online taking business away from physical Privacy (leaks, tracking) Job loss Legal issues: fraud, domain name conflicts, cybersquatting, domain tasting, taxing ecommerce, copyright

 International jurisdiction complicates things  See final lecture in IS block cloud computing: what There is no cloud, it’s just someone else’s collection of computers” why (advantages),  Focus on application, not infrastructure  Promotes resource elasticity (storage, network, processing) [next slide]  Availability and Service Level Agreement  Disaster recovery  Move from capital to operational expenditure (CapEx to OpEx)  Built-in Security protocols

Different types (IaaS, PaaS, SaaS), IaaS: Replacing in-house hosted resources to:  Migrate legacy systems to the cloud  Replace ageing/obsolete infrastructure  Lower physical resource requirements  Hosting web sites with high availability

PaaS: For new application development where:  Data requirements are dynamic  Size of user base is unclear or non-static  Burst” processing behavior is likely SaaS: For providing applications where:  Requirements are standard (e.g., email)  A subscription model is valid (i.e., regular usage)  Rolling out updates and maintenance is difficult

issues/risks.  

Someone else’s computers ... Data ownership? Privacy?

 

Legal jurisdiction? Accountability?

Customer Relationship Management (CRM): a strategy, supported by an Information System.  Identify "touch points", collect & consolidate data, and use it ... uses include operational (for contact with humans ["customer facing"], and with automated systems ["customer touching"]) and analytical.  CRM strategy is one way of supporting Differentiation (be different by offering a better customer experience.

Supply Chain Manufacturing (SCM) systems: information system to integrate a supply chain and use information to optimize.  Advantages include faster manufacturing, reduced inventory (especially if can move from a push to apull model), ability to provide accurate estimates, and ability to track properties of raw materials and processes (e.g. environmental sustainability)  Challenges in realizing SCM: collecting information (ideally automatically, e.g. using RFID), and sharing it between organizations...
