Labour Issues
Should any member of the Development Team become unavailable for an extended period of time, the project may not be completed on previously forecast dates.
Organizational
In this context Organizational Risk refers to risks that arise due to poor communication, improper implementation of business rules and development processes.
Overconfidence
A common trait in expert professionals is to skip paperwork and work according to an improvised schedule
slide into code-and-fix chaos
Organizational Commitment
Lack of acceptance of the tools and protocols can introduce communication problems, defects, and deteriorated performance
fail to properly document work
take shortcuts
skip meetings
Overwork
If not managed, feature creep may affect staff stress levels resulting in deteriorated performance
Unrealistic Objectives
The Client may have the expectation to replicate the legacy system with newer technologies. Besides the developments in technology, since the legacy system was built, the consumer attitudes and behaviour have changed, and so did the nature of online commerce. Due to the maturing and proliferation of APIs and other services, the current online business model is a lot more modular with a strong trend towards maximum decomposition of monoliths.
Project Management
Scope Creep
Poor communication and unclear project goals can cause large features to be added forcing unsafe schedule compression, and technical debt.
Schedule Planning & Cost Estimates
The necessity to dismantle parts of the legacy system, and to reproduce their functionality in the Product introduces a degree of uncertainty.
Technical
Quality of Technology
Any complex implementation will have defects such as programming bugs and undesired side-effects. Insufficient code quality control resulting from inadequate code reviews or lack of unit and functional testing will increase rework and other costs.
Performance Risks
The current implementation of the website is tied to the legacy technology that acts as a performance barrier for the whole organization. To prevent overloading the legacy system, special considerations have to be made to operate within the tolerance limits of the legacy system.
Complex Technology
For historical reasons the Client stores data, and processes payments and memberships using a separately configured set of legacy technologies. That setup is not consistent with the industry’s best practices. Maintenance of that legacy system, and the requirement to integrate it with the website constitutes an overhead, and reduces the Development Team’s ability to produce accurate estimates.
In accordance with Agile risk management principles, the Project Team commits to making risk management an intrinsic part of project lifecycle by encouraging transparency, inspection, and adaptation in all aspects of the project where risk is present.

Further, a secure back-end that can be used to perform these administrative functions:
Terminé
Back Store
Monitor and control the storefront.
Email Manager
Monitor statistics on transactional email activities.
Content Management (CMS)
An interface allowing the client to create, update or delete articles as well as control other items related to appearance or behaviour of the website.
The completed product will be a website which consists of a public front-end and a secure back-end. The front-end will have the following features:
Responsive Design
The website will employ modern browser technologies to take full advantage and maximize the use of features offered by mobile devices when viewed on mobile phones and tablets.
Storefront
Ability to select packages, and a secure checkout page where customers may enter their payment details.
Contact Form
Separate page
Member Registration
Consider possibility to have the registration form on marketing campaign landing pages, as an app in Facebook, and so on.
A separate page that contains a form with fields for the profile information. Allow possibility for a two-stage registration and use of third parties for authentication (Facebook, Google, Twitter).

It is important for the individuals doing the work to have some knowledge of the business case in order to understand the client’s needs and expectations.
we will acquire a DB of 1e5 customers, and we'll start emailing them in August
we plan to increase traffic 10x in the next 6 months
supplement Social Media efforts; most interaction takes place on Facebook
become the main hub for information, sales, memberships
Social Media
A number of organizations have moved their principal points of contact with public onto social media websites such as Facebook. The nonprofit org does not currently have a Facebook page, but it has a website. Although social media presence is important for the nonprofit, at this point, a website upgrade is a more valuable project than full migration to Facebook.
The Client is constrained to have the project fully completed by October 20XX. Any later delivery will result in lost sales and publicity for the Client.
A Canadian non-profit needs to have its website upgraded. If this project is not undertaken, the client will lose revenue from lost sales and membership.
Why was the project initiated?
Demand
the Client may reevaluate Business Need in view of the project initiation findings
e.g.
add/remove/change features because of high or low complexity
complexity often becomes more visible when we start researching
change deadline if we can deliver a working product with basic critical features 3 months earlier, and then continue adding and improving features
What will happen to the client if project is not undertaken?
Communication Channels
external
Regular meetings with the client allow the Project Team to prioritize work items that will bring the most business value to the client. Frequently scheduled inspection/adaptation sessions with the client assure that the Development Team can respond to external changes with agility. For this project it is recommended that a Review meeting with the client or a client’s representative be held every week when the Development Team will demonstrate, and the Stakeholders will inspect and accept the deliverables that were scheduled to be built during the week. The Stakeholders will apply the Acceptance Criteria that are agreed upon at the Retrospect meeting.
To remain responsive to external factors, and to incorporate feedback from Client quickly, Project Team is committed to maintaining frequent communication with Client in capacities outlined as best practices for Agile projects.
internal
meetings
Initial
Project Team recognizes value in Agile approaches, and will implement high-bandwidth communication between team members by aligning with meeting structure and frequency according to the best practices of Agile management.
Detailed
Retrospect. The Development Team will meet at the end of every week to review and adjust the Acceptance Criteria, and to assess the team efficiency during the previous week. This meeting is timeboxed at 3 hours.
Daily Stand-up. The Development Team will hold daily Stand-up meetings that will be timeboxed at 15 minutes.
Planning. The Development Team will meet in the beginning of each week
Efficient self-organizing teams require high-bandwidth communications in order to maintain optimal levels of agility and responsiveness, and to take full advantage of each others’ specific skills. Team meetings are collaboration tools, they constitute key opportunities to cultivate and practice transparency, inspection and adaptation. Therefore, the Development Team will ensure proper communication by holding at minimum the three regular internal meetings described below:
phone
chat
Infrastructure
equipment
development computers
two monitors
facilities
Syspark offices
Syspark makes its office available for the Development Team to perform work on the deliverables, and to hold meetings. The Development Team will determine the most efficient location and configuration to perform their work. The team should be able to explain how its choice improves efficiency.
