6. making changes to systems

Why must accounting systems be regularly reviewed?

To ensure they remain effective, efficient, secure, compliant with regulations and fit for purpose as the organisation changes.

What are the main reasons for changing an accounting system?

System weaknesses, fraud or errors, personnel changes, business strategy, new technology, cost reduction, changing information needs and regulatory requirements.

How can personnel changes trigger a system review?

Department mergers, new managers, rapid recruitment or high staff turnover may require revised responsibilities, authorisation levels, procedures and training.

How can business strategy and technology trigger accounting system changes?

Expansion, acquisitions, diversification, new software, hardware or cybersecurity threats may require new processes, reporting and controls.

What financial reasons may prompt an accounting system review?

High operating costs, adverse industry comparisons, poor efficiency, opportunities to reduce waste and the need to improve profitability.

Why are timely and regular reviews necessary even when systems appear effective?

Small changes accumulate over time and may create inefficiencies, outdated controls or weaknesses that could eventually cause errors or fraud.

What is a post-implementation review?

An assessment after a new system begins operating to check whether it meets objectives, identify problems and recommend further improvements.

Give examples of small changes that may improve accounting efficiency.

Online banking instead of cheques, electronic receipts instead of paper, online ordering, revised payment schedules and updated approval procedures.

How can regulatory changes affect an accounting function?

They may require revised accounting policies, software, staff responsibilities, data collection, reporting procedures, internal controls and training.

Give examples of regulatory changes affecting accounting systems.

IFRS 15 revenue recognition and disclosures, payroll Real Time Information reporting, anti-money-laundering checks and waste management regulations.

Why should organisations monitor future legal and accounting requirements?

To identify changes early, budget for them, adapt systems and staff procedures and meet statutory deadlines without last-minute disruption.

What three factors determine the type and scale of change required?

Seriousness of the problem, scope of the proposed change and context, including how employees and stakeholders perceive the change.

What is transformational change?

A major, wholesale change to systems or operations, such as replacing separate accounting functions with one centralised integrated system.

What is incremental change?

A small change or a larger change implemented through gradual steps, such as progressively integrating individual accounting subsystems.

How do transformational and incremental changes differ?

Transformational change makes a major change at once, often with greater disruption;

incremental change introduces improvements gradually, allowing adaptation and review.

What is cost-benefit analysis?

Comparing all relevant costs and benefits of a proposed change to determine whether it is financially and operationally worthwhile.

What are tangible costs of an accounting system change?

Quantifiable costs such as software, hardware, licences, consultancy, staff training, temporary cover, installation, maintenance and upgrades.

What are intangible costs of a system change?

Difficult-to-quantify disadvantages such as employee stress, reduced morale, customer dissatisfaction, reputational damage and disruption to service.

What are tangible benefits of a system change?

Measurable improvements such as reduced processing time, fewer staff hours, lower operating costs, less waste and increased sales.

What are intangible benefits of a system change?

Improved reputation, customer experience, employee morale, working conditions, motivation and quality of management information.

What is opportunity cost?

The value of the next-best alternative forgone when resources are used for a particular decision, such as spending money on software instead of marketing.

What are relevant costs in decision-making?

Future costs and benefits that differ between alternatives and therefore affect the decision; unavoidable or unchanged costs are generally irrelevant.

How is the net benefit of a proposed system change calculated?

Total benefits minus total relevant costs over the same period. A positive result supports the change but non-financial risks must also be considered.

How are initial costs and running costs treated in cost-benefit analysis?

Initial costs are incurred when implementing the change;

recurring running costs are included for each year of the assessment period.

What other factors should be considered alongside cost-benefit analysis?

Fraud risks, SWOT findings, performance scorecards, customer service, staff morale, legal compliance, future reporting needs and long-term strategy.

Why should a proposed accounting system be future-proof?

It should accommodate expected business growth, changing information needs, new regulations, software updates and reporting requirements without expensive repeated replacement.

How should accounting system recommendations be justified to management?

Explain the problem, proposed solution, relevant costs and benefits, assumptions, operational effects, risks, mitigating controls and reasons the option is preferable.

What should an implementation plan include?

Objectives, responsibilities, timetable, milestones, budget, software and equipment, consultancy, training, testing, contingency costs, communication and monitoring.

What are the six main stages of the change process?

1. Evaluate the existing system

2. recommend solutions

3. communicate with stakeholders

4. train users

5. implement the change

6. review its effectiveness.

What happens during the evaluation stage of system change?

Identify system weaknesses, assess their seriousness, determine whether change is necessary and examine whether the current system meets requirements.

What happens during the recommendation stage?

Propose suitable solutions, consider previous attempts, timing, expertise, staffing requirements, likely benefits and potential implementation difficulties.

Why is communication essential when introducing system changes?

It explains the reasons, benefits, timetable and effects of change, allows feedback, reduces uncertainty and helps gain stakeholder support.

Why must staff receive training before or during system implementation?

To develop competence with new software, controls and procedures, reduce errors, meet compliance requirements and minimise disruption.

What happens during implementation and review?

Implementation follows a planned timetable with testing and safeguards;

review checks whether objectives were achieved and identifies any corrective action needed.

What is resistance to change and why does it occur?

Opposition, delays or lack of cooperation caused by fear of uncertainty, job losses, increased workload, unfamiliar technology or loss of responsibilities.

How can management reduce resistance to change?

Communicate early, consult staff and representatives, explain benefits, provide regular updates, offer training and support and involve users in planning.

How can changes affect employees and other stakeholders?

Employees may face new roles, workload or training; managers may receive different reports; customers and suppliers may experience changes in service or transactions.

What are the three main approaches to changing from an old system to a new one?

Direct or transformational changeover, phased changeover and parallel running.

What is direct changeover and what are its advantages and risks?

The old system is replaced on a designated date.

It can be fast and inexpensive but carries higher risk of disruption, errors or failure if the new system is not ready.

What is phased changeover and what are its advantages and risks?

The new system is introduced in stages or departments.

It allows testing and adjustments with less immediate risk, but takes longer and requires coordination.

What is parallel running and what are its advantages and disadvantages?

Old and new systems operate simultaneously so outputs can be compared.

It reduces data-loss and processing risks but duplicates work and increases costs.

What are pilot testing and test data in system implementation?

Test data checks that a new system processes transactions correctly before live use; a pilot introduces the system in one department or small group before wider rollout.

What controls are needed when migrating accounting data?

Back up and cleanse existing data, check completeness and accuracy, reconcile opening balances, restrict access, test transfers and retain secure audit trails.

What should management decide about the old accounting system during transition?

Whether to archive it, deactivate it or run it temporarily in parallel, while preserving required records and preventing unauthorised access.

What are the main practical controls for a successful system transition?

Assign leadership, schedule milestones, choose suitable timing, train staff, provide temporary support, test and reconcile data, manage user permissions and monitor progress.
